Listen to Cel phones live on the Internet?
An anonymous reader sent us this link (note
that it is a shoutcast feed). Essentially, it is scanning
open airwaves for cell phone calls, and rebroadcasting them over
the Internet. Now I'm curious- is this invasion of privacy legal
or just proof that we all ought to be encrypting everything? What
do you think?
This is why I use GSM.
It's a thankless job, but I've got a lot of Karma to burn off
The Secondary domain is registered to an American company. This does not mean that eggshell.mudservices.com is in the US. I also tried this, and found the same results, but decided that it's impossible for ARIN or the Internic to know exactly where each IP or Domain REALLY points...
Then again, you are probably right. The server probably IS in the USA..
You probably refer to the case of the couple which had a scanner, and were taping it, when they happened to hear Newt Gingrich's call (containing embarrasing details of mudslinging strategy). They turned it over to a Democratic Congressional Rep., and and HE released it to the press, et. al.
Unless this event you occurred happened after the one I describe (and as a result of it, which I doubt), then you are simply wrong. The couple may have been given a light punishment (since it was illegal), but they were hardly the Democratic elite, nor did they target Newt, nor did they tape "all his calls".
BTW. The Democratic leader who released it was largely criticized in the media, and in the court of public opinion, while Gingrich's phone conversation, although potentially damaging to him, was not pursued as a news item since the invasion of privacy issue (and manipulation by opponents who released it) was considered a bigger danger.
> I should have the RIGHT to listen to it if I see > fit. It's MY AIR too is it not?
... it shows up very often, mostly as with a very big "MY" in front of it.
Yes. Still your freedom ought to stop where others starts. This argument about "freedom"
Not intercepting other peoples communication is about showing respect for other beings too. If it is legal, do not do it. If it is not, bad luck if you get kicked somewhere and if someone does not know yet is is possible to intercept calls it must be made really public at least. Any "you"'s here not to be taken personally.
It is your problem to protect yourself. The government doesn't protect you. They only step in after you catch the terminal end of a 7.62x54R boat tail round to the head, by trying to apprehend the schumck who pulled the trigger. If you think the government protects you sir, you need a reality check. And that people don't take any precautions against snipers, speak for your self, I work underground. :-) (of course on a day like today I would gladly trade my at-work-sniper-protection-system(tm) for a nice large window, but alas it can never be ...)
Now, you have only the rights you were nerously allocated by the current democratic system, not what you think you have, no matter how these rights sound reasonable it sounds for your mind. By not appreciating the written law, your gnorance would end you up in jail. There are no slashdot, computers, the Internet, girls, cinema, good food and many many other useful things there. Take it easy.
You are quite WRONG. A right is NOT granted by the government. That would imply it could be taken away by the government. A right is something you are born with. (Like life, liberty, etc. you see where this is going? You can go look it up yourself. The document is rather well known.)
I've also seen it argued that a law that can never be enforced (pretty hard to reliably monitor who's receiving what) isn't really a law, but that gets rather messy.

"There's no secret. You just press the accelerator to the floor and keep turning left." -- Bill Vukovich
First, back in 1995 I had initially thought of interfacing a old motorola flip phone to web, allowing web surfers to control the cell in test mode.
Which means, *I*, the ISP or owner of the IP address could not be held responsible to illegal monitoring of a cell phone call. The web surfer would be the party commiting the violation. The audio stream would go only from the phone to surfer (no broadcast involved).
At any rate, I decided against it. The primary reason for this decision was the stupid shit that I would constantly hear. This was right about the time that the KC cops were getting their encrypted radio system, it was the year KC made it into the list of top 10 murder capitals and most of the monitoring was done within cells that were in less desierable areas of the city. From what I was hearing on the cell frequencies, the stupidity was not limited to joe citizen.
Now when I say "stupid shit", I'm not talking about inconsequention noise of the average human existance. I'm talking about people selling drugs, cops using cells to communicate so their conversations wouldn't end up as part of the perminite record, murders being arranged and all sorts of wild shit that kinda' put a new spin on my view how the world works. After spending about 100 hours listening, I realized that it would be just plain dangerous to compromise the fraud sactanty of the cell phone.
Maybe I was just in the right place at the right time, or maybe people make a lot of assumptions about technology that "liberates" them to say things that they never contemplate saying normally. Whatever the case, it's clear that technology requires a certain amount of "protection" to remain socially paletable at any given instant in time and history.

Sure it's illegal. So what? Did Newt a lot of good to bitch about it being illegal.
You want privacy? Encrypt it.
Just think of it as a condom an the age of electronic AIDS.
No. My digital cell (GSM) was $30. (My company sells them, it was at cost.) It retails for $50 normally, without a service contract, free with one.
Actually, I believe that that was a valid legal defense at the time. The laws regrading that might have been changed but I distinctly recall that at the time, that person mounted a successful legal defense. In addition, I dont know if it is illegal to listen to cell phones in the privacy of your own home or if it is illegal to use such knowledge for personal gain. I seem to have known once, but I have forgotten.

But that is based on a lie. You ARE broadcasting, even if you think it is point-to-point "as far as you are concerned". If you yell to someone across a field, you are broadcasting, even if your intention is that it should be a private conversation. Why should your misconception be legal grounds for incarcerating those who decide to listen?
If the phone service providers assure you that they are protecting you're conversations, and they broadcast it without encryption, or don't tell you they are broadcasting it, they they are lying. Make them fix it! Force them to use encryption! (It really isn't that difficult to do, excluding international regulations)
Legislation won't solve the problem if someone wants to hear your broadcast messages. Now, without warrants and proper standing, such intercepted calls should not necessarily be used as evidence of criminality (You listening Lucy Ann Goldberg, you evil twit?)
I feel your pain. I'm in the dallas area (carrollton) and I get many of the same problems. I have a friend who works for Sprint and he was able to explain the problem to me: as I understand it, the towers for Sprint's "digital network, built from the ground up" were actually purchased from another company. To save money and increase the network area, rather than adding more towers, Sprint turned all the transmitters all straight up as opposed to down toward the ground, resulting in HUGE footprints that all interfered with each-other. Now Sprint denies this whenever I ask them, however If you complain about dropped calls with a full signal indicator, they will generally give you a small air-time reimbursement, however I have yet to see any actual improvements in service. As soon as I get a raise, I'm switching to AT&T or SWBELL.. Those Nokia phones are the shit. Anyone have any input on the quality of those providers?

It is easy to listen to an analog cellphone call. The scanners that are available at Radio Shack may require a few minor adjustments, but instructions are available. Most people believe that the risk of being arrested for listening into the conversations of others is very low. If you are using a cellphone, take reasonable precautions against scanners. So, the reasonable conclusion is that you should not assume that cellphone calls are secure.
Sorry, You've got this backwards. Any cordless phone, (there may be an exception on 900mhz), is LEGAL to listen to, while it is illegal to intercept ANY cell or pcs calls. Most cordless phones operate on what the FCC has branded a public home freq. I don't know the proper FCC regulations on 900mhz though. Any one who says it is legal (in the united states) to listen to cell phone calls does not know what they are talking about.
What will they come for next?
Everytime I use my cell phone I act under the assumption that it is being broadcast to everyone. It is no different than if I was using my amateur radio to communicate with other hams. It is NOT a point to point only media! If you're concerned then we need something like digital spread-spectrum like the kind that comes on alomst ALL decent cordless 900MHz phones these days or we need strong encryption. So, next time you use your cell phone or cordless phone... say hi to your neighbors. I used to listen and I know many people still do.
My Sprint PCS phone has two "privacy" settings, normal and enhanced. I don't know if that means encryption... I'll have to bug customer service and find out.
man ya just gotta luv that slashdot effect man...

To err is human, to really screw things up, you need a robot.
You should be jittery. I don't use them.
My friend and I once built a scanner to listen to the cordless phones around my apartment complex.
Fascinating stuff, and frighteningly easy.
It's a thankless job, but I've got a lot of Karma to burn off
The server is actually eggshell.mudservices.com,
theoretically owned by a company that rents out
accounts on a collection of linux servers to people
for the purpose of MU* hosting. Someone probably
decided to rebroadcast this shoutcast stream on
their account, along with running a mud or
whatever. Doubtless they will be surprised when
mudservices pulls their account, not having
realized that there would be anything wrong with
running a shoutcast server (I think that accounts
on providers like that generally share computers,
depending on how much they pay, so the person is
probably violating some sort of rule in the
agreement they signed)
Most digital phones sold in the U.S. have some type of encryption on them now. Analog, of course, doesn't get that luxury. I guess that is why Analog is dying.
Granted I don't want people listening in to my phone conversations (although 99.99% of the time I don't say anything that I would really care if someone else heard), and thus my cordless phone uses spread spectrum stuff. However, how can you make it illegal to listen to a broadcast that is *everywhere*? What if I developed an organ that allowed me to sense radio transmissions? Would *I* be illegal? The radio transmissions are going right through me and you and everyone else! Banning the sale of recievers that can pick up these frequencies is pointless. I am in favor of the laws that prohibit disclosure, but not the ones that ban listening. I don't want people to listen to me, but I am also aware of how ridiculous it is to say that you can't listen to the signals that are passing through the air all around you. In summary, listen, but don't tell, although that sounds about as ridiculous as don't sense the radiation passing through your body...

In europe, and probably other parts of the world, we already use digital cellphones, on the GSM net. I'm not an expert on this, but as far as I know, you cannot intercept a GSM call, unless you intercept it at the time the call is first made. After that, the encrypted signal key is changed at such a rapid rate, that only the two end-points of the phone-call is able to decrypt the signal again, having the keys. This is all done with a digital SIM card, that each phone has, and which is unique. You can also store phone# and such in the SIM-card, and thus transfer the data from phone to phone. Each SIM also has 4 sets of codes, one pair of regular, and one pair of Unlocking keys (4 and 11 numbers), and a SIM will not work anymore if you enter the wrong number 3 times in a row etc. (You need to use the unlock key to make it work again). :)
It might not be 100% perfect, but it is a secure and good way to do phonecalls throughout europe.
Analouge cellphones ? Thing of the past here
Heh, bad luck for him if he was listening in on an Internet connection...
Not necessarily....I would never have touched the interstate without my cell phone in my trusty-but-you-just-never-know 10 year old Civic. Even in my new car it came in handy on a back country road when a dipshit kid crossed the centerline in a van and head on'ed a little Sentra. Use them responsibly and not while you're driving the kids to soccer practice in the Land Cruiser/Windstar and you should be okay.
I believe that intercepting cell phone calls is illegal in the US. RF scanners aren't allowed to be sold that are tunable to cell phone frequencies and haven't been salable for some time. Scanners sold prior to this prohibition aren't supposed to be used for monitoring cell phones either. However there are lots of people that are quite willing to break the law. Hence encrypting your cell phone traffic is a good idea if you value your privacy.
I liked AT&T... a emphasize liked though... Here in College Station/Bryan AT&T is being "bought out" by Houston Cellular. While I used to have Long Distance for free anywhere in Texas, Houston doesn't offer that, and they charge the same amount. I'm pretty ticked about it, and I am not switching to Houston Cell. Prior to that, I've had excellent service.

Last time I checked, it was illegal to monitor cel-phone calls - although it's possible with a $50 walkie-talkie scanner from Radio Trash. Yes, we probably should be encrypting, but digital cell phones are still really expensive (even after the two-year-service-contract-discount - try $0 for analog when you buy service, but $150 and up for digital even after buying service). Until they come down in price (not soon - still have to absorb the cost of building all those digital towers) it's best to just not discuss anything sensitve on a cell phone. Remember Pulp Fiction? "I don't know you... Prank call! Prank Call!"
Comments welcome.

It was Newt Gingrich being taped, but the legislation was passed before that. It was taped near here in North Central Florida and handed over to our Congresswoman. A lot of controversy was raised as to why they were listening, why they had the equipment (scanners are illegal anyway in cars in FL, except for hams ). Never turned out to be much of anything though. Just goes to show ya....ask my friend who checked his bank balance (DTMF codes sending account and PIN)....yes....let's get encryption
remember the distinguished gentleman from Virginia that proposed a law banning spam some time ago? at the end of that bill was a bit about not letting a prominant local phone carrier use the Internet to broadcast cellular signals
no relation, probably
What about *International* calls? Is it illegal to intercept a cell phone call from Canada from within the US? What about vice versa? Can canadians intercept US phone calls legally? And what about calls from airplanes in neutral zones? And of course, what about intercepting calls from outer space (satellite spying)? It seems like we're in for a lot of international legal problems as countries get closer in terms of travel and more and more connected in terms of communications. Maybe some day there will have to be a system of international law...
It doesn't matter if that link is legal or illegal, its being done, and that could be ME on the other end of it everyone is listening to talking about my SS#, and my vault combination, and other assorted PRIVATE issues. Or it could be the GOVERNMENT people talking about the LATEST AND GREATEST NUCLEAR TECHNOLOGY.
Its no wonder the Chinese got our Nuke technology.. We need to encrypt EVERYTHING is 2048bit keys *NOW*, with NO BACKDOORS, for _EVERYONE_.
My scanner seems to be able to scan the 806mhz - 956 mhz range, but I can't listen to the 175 - 406 mhz range or the 513 - 805 mhz range... Anyone know why? Is this because of the Govt/FCC regulations, or is this a cheap scanner (Radio Shack 50 Channel)?
People need to realize that nothing is totally private. Anything which has a distance greater than zero between point A and point B has the possibility of being intercepted somehow. Thus, the focus must shift to making it as difficult as possible to decode the intercepted transmissions.
Dude, they block the cell regions on scanners... t
depending on the model # they can be re-enabled
Unfortunately, I can't read that page. But I can tell you its easy to take an old Motorola bag phone, read the "Motorola Bible" about the test mode, and you have a scanner. Look it up on the search engine of your choice and start listening. You can also transmit and adjust power levels too. How do cellular technicians track this kind of abuse?
Needless to say, this is why I got a digital phone. It might not be secure, but its not as easy to eavesdrop! The only complaint I have is the audio quality is barely audible, especially when talking to another digital cell phone. Is the poor audio quality just my location or does it plague certain types of phones?

Welcome to the #DwC Frequently Asked Questions guide. Here
you'll find the answers to most of the common questions asked
regarding #DwC.
Q1 -- What is #DwC?
A1 -- #DwC is the place where you can find listeners of [DwC]'s
scanner broadcasts. [DwC] utilizes his scanner to
intercept cellular telephone conversations.
Q2 -- How does #DwC broadcast to me?
A2 -- [DwC]'s scanner output is hooked up to his computer's input.
Through the use of SHOUTcast (www.shoutcast.com) streaming
MP3 technology, this sound data is encoded into a form which
can be played by players such as WinAMP, x11amp/xmms, mpg123,
and others.
Q3 -- What kind of equipment does [DwC] use? Can I stream to [DwC]'s
servers also?
A3 -- [DwC] scans the airwaves with a Uniden/Bearcat BC200XLT scanner.
At this time, no other scanners or broadcasters can use [DwC]'s
servers or relays.
Q4 -- What are some of the relay servers that I can connect to and
listen with?
A4 -- The relay servers are changing and new ones are being added often.
To find current open servers, visit #DwC on EFnet (servers are
listed below.) You can usually find a list of some of the open
relay servers in the channel topic. You can also visit the #DwC
website at http://dwcefnet.cjb.net.
Q5 -- How come [DwC] doesn't change the frequency even though I
flooded the channel with "CHANGE THE CALL!!!" for two minutes?
A5 -- The frequency scanner is set to automatically scan the airwaves.
When a call ends or the signal becomes too low, the scanner
will stop broadcasting that frequency and scan for another one.
Q6 -- HEY! Can I have ops in #DwC???
A6 -- No.
Q7 -- Please? I promise I won't be mean!
A7 -- No.
Q8 -- What exactly is a "relay"?
A8 -- A relay server connects to the main broadcasting server and
then re-broadcasts the audio stream. This prevents the main
server from becoming overloaded with clients.
Q9 -- How come when I try to connect to a relay I get the message
"401 Service Not Available"?
A9 -- The 401 error means that the main server has stopped
broadcasting. This can be due to a number of things, such
as the server being temporarily disabled. If the main server
is disabled, all relays connecting to it will stop broadcasting
also. If your relay goes down, PLEASE DO NOT ASK in the
channel "HEY DID EVERYONE ELSE'S JUST DIE ALSO?!?!?" This
floods the channel and is EXTREMELY disrupting!
Q10 -- Can I run a relay server?
A10 -- Running a relay server requires time and effort on your part.
You should have at the bare minimum a cable modem connection.
No, a 56K modem is not good enough. Make sure you set the
maximum number of clients for your server to a suitable number
for the speed you are on. Even a T1 can support only about 32
users; if too many clients connect, the broadcast becomes
choppy for everbody. If you meet these minimum requirements,
send a
Other things to remember --
- If you repeat text/flood in the channel, you will be kicked
and/or banned.
- If you advertise/spam in the channel, you will be kicked and/or
banned.
- If you use excessive CAPS in the channel, you will be kicked
and/or banned.
If you have any questions to add see us in #DwC.

According to the whois server at ARIN, the nameless IP address on the web link reverse maps to:
Internet Unlimited (NETBLK-IUINC4-FASTNET)

Since this is within US borders, the Communications Act of 1935, prohibits the divulging of private radio transmissions without consent of the parties involved. Even the sweeping anti-freedom amendments to the Act in 1986 and 1994 aren't needed to point this web site out as being illegal.
Free speech does not allow one to break the law.
If he's doing it as an act of civil disobedience, it's still illegal, even if he's morally right. The law and the right thing to do are not always equal.
My son told me about listening
to phone calls on the upper
channels of UHF. He probably
read about it on the Pesky Internet.
We have tried it several times. It does
work.
They do it all the time whenever they access an https site. Sometimes, they even know it's secure because the browser pops up an information box telling them.
I do wonder if it isn't possible to have digital phones at least automatically encrypt when connected to a (compatible) digital phone.
Of course, then one has to consider encryption technologies that can survive the phone-D/A-slight analog noise-A/D-phone sequence that many cell phone calls go through. Not a trivial matter.
Like I said, encryption is a good idea. I don't expect cellular conversations to be safe, at all, from anyone with dishonorable intentions. But, what is the use to anyone of publicly broadcasting my messages? Forget stolen information, that could just be downright embarrassing, plus it opens up my private information to people who might not have found a way to get it before. This broadcasting site is just ludicrous.
--Carl
Rainbow Technologies is one of many possible places to start for real encryption.
IIRC, digital cellphones use spread spectrum technology which is an effective pseudoencryption method for protecting against casual dial spinners.
Crap. The current laws are like saying a guy can walk into a room and yell at a certain volume, and anyone who listens to him is breaking the law. We have a half-assed communications system... we need to FIX it, not make silly laws about it.

As a matter of reference, all cellphones(analog) have scanners built into them, though you have to set the channel, you can easily skip from channel to channel till you find something interesting. It is part of a diagnostic and programming mode all analog cell phones have.
It used to be that as long as it traveled through the air, and onto (and into) your property, you had the right to monitor any and all radio communications, and that includes phone conversations. You were prohibited from divulging what you heard to anyone, but you could listen to your heart's content. That all changed a few years ago when the old-guard cellular industry successfully lobbied Congress to pass a law criminalizing monitoring radio waves that carried cellular phone calls.
This was a major blow to freedom! For the first time ever, the "land of the free and the home of the brave," "with liberty and justice for all" had gone and done what only the Godless Communists were supposed to do. Thank God the Internet came along!!!
Regardless of the correctness of this new law, rebroadcasting transmissions heard third-party is a definite no-no. And it really has nothing to do with invasion of privacy. It's more about protecting big business than protecting personal conversations.

>...Newt Gingrich's call (containing embarrasing details of mudslinging strategy).
Actually if you read the unedited transcript, you find Newt discussing his previous censure with his lawyer and several republican congresscritters, but according to democratic newspeak, discussing his case with his lawyer is a violation of his censure.
Ya gotta love politics...
I know about that... But AFAIK, the 800 - 900 mhz frequencies were the cell phone ones. For some reason, they work (without modification). I was interested in what frequencies the scanner couldn't get and why... Thanks anyway.
Sorry for the following if it offends anyone. If signals from some source, public or private come on my property or through my body then I *do* have the right to do what ever the hell I want with that signal. Be it monitoring, descrambling, or nothing at all. If you don't want people listening to your transimissions in any intelligeable form then FUCKING ENCRYPT IT. If you can't think of a way to do this then you don't deserve any privacy. As for satellite and cable TV, I know of no one who respects these people. They simply deserve none whatsoever. They transmit this bullshit over a large spectrum and then have the audacity to ask me to pay for it? Hey, fuck you. Find another way to pay for it instead of getting big gov to make everything illegal so you stay in business. I truly wish everyone had the brains to be "TV pirates" then these corporations would have to find a reasonable way to make money. If you can pick it out of the air, then it is yours.
The CPA prohibits monitoring cellular frequencies, as well as cordless phone frequencies, baby monitor frequencies, intercom frequencies, etc.
But does piping the audio onto the net count as monitoring? Aren't the people listening to the audio feeds in fact the ones in violation of the CPA? Does the CPA prohibit a mechanical device such as the receiver/server that puts the feeds onto the net? My guess is that this is a loophole.
The Communications Privacy Act is a rediculous st unt on the part of the government to make cellular phone manufacturers happy. Anyone can listen to the prohibited frequencies without much trouble.

nuthin' but chunks!
'cuz those are TV freqs... Most scanner manufactures assume you already have a TV, I guess...
Yeah, what he said! Radio waves know no boundaries (excepting maybe RFI shielding...) They propagate according to the laws of physics, not Congress, or any other legal body.
That means when you talk on your cell or cordless phone, you are BROADCASTING. Making it illegal to listen to signals that are all around us violates basic common sense, is technically inept and a horrible legal precedent.
Can anyone present a good reason why the responsibility and legal burden of radio privacy should fall on the *listener*? Especially in this day and age when encryption is relatively cheap.
Bottom line is, it wasn't cheap *enough* for the cell phone companies, so they have permanently scarred our legal landscape with stupid laws that try to ensure their customers' privacy by mandating that you and I plug our ears. This of course allows those same companies to now tell their customers that their conversations are safe and private. The Internet equivalent to this silliness would be decreeing it illegal to read a special hierarchy of Usenet newsgroups containing private messages in cleartext, and then mandating that all newsreaders be rendered incapable of reading those sacred groups.
Meanwhile... Last time I checked, it was illegal to curse on a cell phone, by order of the FCC. Would that perhaps be because they understood that radio is inherently a broadcast medium and that anyone might just tune in? How does that fit with a law that prohibits one from listening to an unscrambled analog broadcast?
It used to be quite easy too. Anyone with an old TV that goes up to UHF channel 84 can tune cell bands. Many older scanners receive cell or can be readily modified to do so. Now it's getting difficult to buy even high-end RF test equipment that doesn't have the cell band blocked out. stupidstupidstupid! Although, "unblocked" radios are readily available from distributors in Canada, where apparently the cell phone companies have been unsuccessful in purveying such collossal legal stupidies.
What really frosts my shorts is that at some point, analog cellular will be long gone, but this #$@#! law will live on, leaving a f$#$ing crater in radio reception capabilites for years to come.
Why do I care? Well, it's certainly not because I get my jollies listening to people talk on the phone. Most of what you would hear on a scanner is about as exciting as watch paint peel and it's been a few years since I bothered with it in any meaningful way. As an occasional scanner listener and ham (N3HAZ), it's a matter of principle and "technical purity" for me to expect that laws covering technical matters have at least some tenuous basis in rational thought.
Harumph!

...remind me to say hi to all the people listening on #DWC.
I don't know about you, but I find this all very interesting, from a legal, social and a technical point of view. There are so many questions opened by stuff like this that I just can't help but be awed by them all.
Personally, (IMO) in the end I think that DWC is doing us all a favor by raising the issues brought up by this. Cell phones are not a new thing, and it just goes to show how naive most people are towards technology.
It's amazing how gullable we all are.

Come on guys, give me a break.
I wanna snoop too!
Right. Part of the reason for this is that a wide variety of household devices use the same portion of the spectrum. Cordless phones and cordless baby monitors, for example. Since I don't want my telephone conversations rebroadcasted on the neighbor's baby monitor, I use a 900Mhz cordless phone. It's digital and encrypted.
I'm not plotting a coup or conducting drug deals, but I still value my privacy.
Wrong. While scanners in Canada can listen to any
frequency being broadcast (I know, I own one) - the courts have likened it to overhearing a conversation on a street corner - it is strictly forbidden to rebroadcast a radio communication which was not originally intended as a broadcast, without the involved parties permission. So this person is clearly breaking the law.
on sony japanese radios (the ones sold in japan -- not in the US) you can listen to the police, cordless phones etc. directly. they have a broader FM range than do the radios sold in the US (these are the normal AM/FM/SW band radios..not a special scanner radio)..
Okay, I'll concede that point. I guess we can't legislate this away, nor would that be right given the nature of cellular broadcasting. Not that the yelling analogy is great -- I *can't* ignore someone yelling, while it's pretty easy not to scan for cell phones. Still, someone ought to give the people making these public broadcasts the message that that sort of thing isn't acceptable (not to me, anyway). It's not like they're provinding a "public service", or anything. If they can't be shut down forcibly, they ought to do it voluntarily. In my opinion, at least. I just can't see a good reason for listening to other people's phone calls...

PCS == GSM, only PCS uses 1800 MHz instead of 900MHz.

If you yell to someone across a field, you are broadcasting, even if your intention is that it should be a private conversation.

I guess we're just going to have to agree to disagree on this one.
I accept your arguement, but do not agree with it.
When I shout to someone, I am forcing all those within ear shot to listen. When you transmit something on a narrow frequency band, the excuse of "I couldn't help but overhear" looks a little shaky.
The bottom line, as I see it, is that if you have to take any action, make any effort to overhear me, then you are purposefully eavesdroping, and so are invading my privacy.
I should probably add that, on reflection, I realise that outlawing it probably wouldn't be enforceable. However, just because something isn't illegal, doesn't make it right.
(Conversely, there are pretty strong arguments for certain illegal acts to be legalised. The US crypto export rules strike me as moronic, as do the ones concerning the export of supercomputers. Large sections of the Criminal Justice Act here in Britain should also be ripped out and burned...:o) )
Tim
It's official. Most of you are morons.
I can't believe no one noticed this:
"Wouldn't you be outraged to find your conversation broadcast?"
All cell phones broadcast conversations - how else could it work. I think a better question would be
"Wouldn't the general public be outraged to learn that cell phones broadcase conversations into public airwaves?"
Cell phones are the equivelent of shouting across a room full of people. The problem is that most people *assume* that they are safe (the salesperson would probably tell you it was secure but most don't even think of this). How many people assume that email is private? should it be illegal for SA to read "private" email that is spooled on their machines?
Sooo many people refuse to give their credit card over shttp but they will on a cell phone. The public needs to understand just how insecure cell phones are and cell companies need to take responsibility to inform customes and take action where needed (ie offer real encryption for those making sesitive phone calls)

1) Some wealthy teenager gets caught listening to cell calls.
2) His parents can afford a really great lawer that playes the censorship card to convince the jury that her/his client was just listening to a public broadcast (which he/she was)
3) Cell companies, in a effort to keep public trust, implement encryption. However, because all the noise the US gov. has made about strong encryption - the cell companies just use trivial encryption that is easily broken (ie xor with some constant value, etc).
4) Someone on the net develops and releases code that can decrypt this trivial encryption.
5) Cell companies, again in an effort to keep conversations secret, lobby and get a law passed in Congress prohibiting the unauthorized decryption of "private" data. However, since it is *possible* (but not very usefull) to decrypt a message in your head or on paper - this will have set the precidence for making laws agains certian types of thought.

There is (IIRC) language in the communications act as amended that says something about the intent of the communicating parties. It is unlawful to intercept communications intended as point to point. Communication intended as a broadcast is not protected (obviously it is legal to listen to your local FM station!). It is also legal for non-licensed persons (all of this is in the US, beyond basic ITU rules regarding amateur radio, I know nothing of these things in other countries) to listen to, for example, two CB'ers or two radio amateurs talking because these are known and intended as broadcast media.
Also IIRC it used to be legal for licensed amateurs to monitor the entire spectrum, including the then RT bands (pre-cellular radio telephone), and, by extension, cellular and cordless phone traffic, but these privledges were specifically revoked in one of the sets of amendments somtime in the last 10 years. (Don't remember when).
Personally, I have always felt that if you want to keep something secret, keep your mouth shut. I do not think that anyone communicating by radio using some simple form of modulation (AM, FM, PCM, USB/SSB, etc.) should have any reasonable expectation of privacy. You can pass all the laws you like, but you can't prevent the interception of signals.
I'm an amateur radio operator. I drive around with a dual-band transceiver in my car (145MHz and 440MHz). Hams on these bands use FM modulation, just like a bunch of analog devices including (non-digital) cell phones. In urban areas there are so many transmitters all over the place that I often experience a phenomenon called "intermod" (intermodulation) which occurs when two radio carriers with wide separation in frequency happen to "beat" at the frequency I am monitoring (the difference between the two transmitter's carrier frequencies is equal to the frequency I am monitorning). If the conditions are right, my radio will then rectify the carrier and the demodulator will try to make audio out of the mixed signal. Often the result is gibberish, but often I hear two crystal clear conversations. This is an accident of physics. I doubt I could be prosecuted, since design of my radio tries to avoid this (lots of band pass filtering and such) and I had no intent to monitor anything I ought not to monitor. Nevertheless, I often hear ten and fifteen seconds of "private" conversation.
BTW, every time someone else buys a minivan and a cell phone, the problem gets worse. More transmitters on more frequencies equals more combinations that yield intermod. RF pollution is a semi-serious problem! (Cell phones are better for this than many systems, because the transmitter power levels are so small compared to more traditional methods of area-wide radio).
So, while the laws are pretty tight, you still shouldn't expect privacy. Even so, rebroadcasting cell phone conversations are something I think they would try to send you jail for...
I don't give a crap WHAT the law says. If you want to keep your conversation private, that's YOUR problem. Go digital, go analog scramble, I don't care. It's your problem.
You know what? I think people are way taking life for granted. They don't take *any* precautions against snipers at all. Well, terrorists and criminals can shoot you anytime, and just because they can do (which is illegal of course), doesn't mean they should be allowed to do so, right? Going with your line of argument, they would point out that it's YOUR problem to protect yourself, get an armor suite, bodyguards, don't go out at all.
Now, you have only the rights you were generously allocated by the current democratic system, not what you think you have, no matter how these rights sound reasonable it sounds for your mind. By not appreciating the written law, your ignorance would end you up in jail. There are no slashdot, computers, the Internet, girls, cinema, good food and many many other useful things there. Take it easy.
Okay, I know nothing about this, but is it even legal for people to connect to this site and listen to what is being rebroadcast?
Just another reason why NOT to use cell phones (not to mention that they cause brain tumors), or even wireless phones.

Speaking as a man who has body armor... No, his arguement is akin to this... Let's say that it becomes illegal to view a nude body that doesn't belong to your child or spouse. If you walk around naked, must it be my obligation to look away or should you put clothes on?
I say it's the latter.
While we're at it, let's make it illegal to be rude. Let's make it illegal to have blue eyes.

If I make a fone call, I don't expect to be monitored, but then again, I don't expect not to. Whenever you speak into a phone, it's not just the person on the other end that hears you, it's also the phones on both ends and all the conductive media in between. If your conversation is soooooooo important, don't go using a technology that broadcasts what you say in all directions.
Personally, I find it pretty amusing...
Yes, most PCS phones broadcast encrypted digital signals.
However, how good the encryption is, is another matter altogather.
If it's not a criminal offense to listen in on the airwaves, is it one to actually then decrypt the transmissions?
____________/\ ____________ \/
This particular site is just using common or garden analogue scanners. American/Canadian mobiles are still analogue (can you imagine that! No international roaming, loads of static- it must be like still living in the 80's).
If US/CA citizens are stupid enough to broadcast their private conversations on an open channel, that's their look out. They can have all the laws they like but it doesn't change the fact that analogue transmissions are no more private than standing on top of a hill and shouting (and what kind of idiot would draft a law that makes it illegal to own a pair of ears?).
I too live near Cheltenham and I take your point about GCHQ. However if GCHQ have a need to listen in to anything, no matter how it is transmitted or encrypted, they will. GSM or GPO, PCN or PGP it makes no difference. The most obvious way of doing this is by being present at the time of encryption or decryption, or by stealing the key physically, NOT by doing the maths. That's why we still pay our spies- to break in to places, plant bugs, and steal things.
The question is... do they WANT to be listening in to your or my lives? The answer I'm afraid is that they have loads more important things to do.
I know enough people there to know that, on the whole, they're an okay bunch of people. Sure there must be more than a few maneovolent bad apples but on the whole, they're good guys.
If you are going to worry about people hacking GSM or PCN then you are going to go very, very mad.

Thought I'd pop in a few facts on GSM.
First of all GSM is not encrypted, the codes mentioned above are just for accessing the SIM card and GSM-network. GSM is, however, hard to intercept, because it uses severely compressed data, and because GSM-network cells are quite small, so a lot of hand-off's and frequency changes take place.
(a hand-off is when you move from cell to cell, essentially from one network antenna to another network antenna)
NMT is a thing of the past in Holland. The phone companies have stopped offering NMT services, moving all their clients to GSM. Losing NMT isn't a big loss tho, the better sound quality and the ability to travel thru numerous countries without losing your network connection make GSM a far superior system.
Actually there is a GSM network in the U.S. covering some of the major cities. (NYC comes to mind). Unfortunately the U.S. network operates on different frequencies from the rest of the world so you still need a different phone there.

Hi evilandi - love the name! :D
It's not living in GCHQ's back garden (I can see the top three floors from my back bedroom) that make me scared, I know they've got better things to listen to than me discussing how many tins of cat food I've got to get on my way home, it's people who get an Orange, or the like, and belive that the conversation is secure. Belive it or not, I've overheard people quoting their credit card numbers over both analogue (I'm also a ham - M1AXR) and whilst overhearing in cafes.
I make it a point not to discuss anything that I wouldn't be prepared to shout across a crowded room over any form of telephone. I'm not paranoid, and I've got nothing to hide but that won't stop me taking every reasonable step to ensure my privacy.
yes, www.dotcomforwardslash.com is my real URL.
Think about it -- if you're making a phone call, cellular or not, do you *expect* to be monitored?
Gee, here I am speaking into an unencrypted radio transmitter. Uh, yeah, I guess I do expect to be monitored. Kinda like if I stick my hand under a running lawnmower I expect to get it whacked off.
Wouldn't you be outraged to find your conversation broadcast?
That's what the phone was designed to do. Broadcast my conversation. Hopefully to a cell site, but just as the lawnmower doesn't know fingers from grass, the transmitter doesn't know a scanner from a cell site.
Humanity has a long history of taking advantage of people who don't understand the basic underpinnings of a technology (there are still folks trying to push "free energy" machines). Ignorance gets you burned - evolution in action.
one can listen to cordless phones on AM radios, if one is close enough

That was the purpose of the Wireless Privacy

It's mentioned a few place including here:
http://www.zdnet.com/intweek/print/970804/inwk0
GSM most certainly is encrypted, and quite strongly too. It uses the A1 stream cipher, which is considered strong, which uses a ~50-bit key. The top 10 bits are blanked, which weakens it. The GSM phone also incorporates the A2 cipher, a weakened cipher easily cracked, and A0 where encryption is turned off.
All three algorithms are built into all GSM phones, and the country of use determines which one is turned on at any one time. I can't remember the key exchange algorithms, but I don't think it's easy to intercept.
I have a Sprint PCS phone, made by Qualcomm and wrapped in a Sony case. Digital to digital calls sound OK, except for the lag. Hard to carry on a conversation with lag.... And this is even to other Sprint PCS customers, although I'm not sure if that even matters.
If that radio signal passes through my body I have a right to receive it (bcause I'm already receiving it.), I don't give a crap WHAT the law says. If you want to keep your conversation private, that's YOUR problem. Go digital, go analog scramble, I don't care. It's your problem.

My old TV picks up cellular phone calls all the time. It's hard to see how it could be illegal for me to tune into channel 4, sit back, and listen to a cell phone call from johny jockstrap asking mom for more tution money cause he blew his on crack. If that's illegal then tapeing somebody's conversation with a hand held recorder is illegal too. Hell, evesdropping on somebody else's conversation would be 'invasion' of privacy.
The data is in the air, regardless of wether it's RF (cell phone) or audio (vocal conversation). When you broadcast your thoughts to everybody, your rights to privacy end.

Well it looks like the servers just went down a couple minutes ago. I bet someone called the wrong (or right depending on your point of view) person and the government caught up with whoever was doing it.
I work at a _very_ large cellular component company, and we squeeze 6 digital call's into 1 frequecy. This is why phone companies like cellular to much more
The DOC in Canada and the federal government have decided NOT to regulate the internet as a broadcast medium.
This seems to be a no-brainer to me. It doesn't surprise me that listening to cell calls is illegal, but real criminals with something to gain from this sort of eavesdropping aren't putting up a web site advertizing what they're doing. If someone really wants to listen to unencrypted broadcast traffic (whether it was intended as point-to-point or not) they will. The solution is not another unenforceable law; instead people need to take reasonable precautions when they're using part of a public spectrum. I agree that it is ethically wrong to intentionally listen in on a cell call, but the bottom line is that the real bad guys are not going to stop, and there isn't a good way to catch them right now.

Hey. It works for the Army.
I'm fairly sure this was made illegal by a law passed recently (after some congressman's cell calls were taped? I can't remember).
But it does make a good point about the need for encryption, doesn't it?
This feels closer to "art" or "civil disobedience" than an illegal act... Actually, if the "artist" billed it as an art form commenting on the silliness of the crypto restrictions, would that make this protected speech?

Correct me if I'm wrong, but is this not the broadcast done from the Holland, MI area (yes, where /. is from) done by some of the people who hang out on EFnet's #linuxwarex? I heard some scanning like this done by someone there about a year ago, except that was streamed with RealMedia stuff...
Legal or not, this sort of thing should not be happening. There should be some idea of reasonable expectations out there. Think about it -- if you're making a phone call, cellular or not, do you *expect* to be monitored? Wouldn't you be outraged to find your conversation broadcast? Well, to those who would broadcast others' conversations, think about the other guy for once. Besides, if someone on a cell phone calls someone on a normal phone, the other guy's privacy is threatened and he doesn't even know it.
I hope whoever is doing this gets shut down, pronto...
I think broadcasts like this are a great argument for encryption, though, even if it should be unnecessary. I know it'll be a long time before I talk about my world-domination conspiracies over cellular telephone.

My prof at UW in my new media communications class (CMU 300) stated that listening in to a "wireless" (PCS or cell) conversation is legal--supposedly because it traverses public airwaves. (Fortunately, most PCS services are encrypted.) On the other hand, listening in to a home "cordless" phone conversation is illegal, because it constitutes a tap on a wire line connection.
no you can't buy these anymore. Grove won't sell them. I don't even know if GRE still makes them. These units are now considered illegal for use under that pinko commie bill that congress passed - any device, whether internal OR EXTERNAL that modifies the radio in any way is illegal.
Grove quit selling them over a year ago. I know, I bought one when they announced they were going to quit.
If you go to #dwc on effnet, you'll see that the scanner is in Vancouver, Canada. Cell phone scanners are not illegal there.
I don't have Shoutcast, so I was not able to listen in on this. My prediction is that within a few hours, the Slashdot Effect will call so much attention to it that the site will be removed.
This isn't too big a deal for me. Granted, I value my privacy and don't want to be intruded upon but it would not surprise me if I found that people were listening in. When people first found out that it was easy to listen in on cordless-phone conversations people were concerned but that didn't deter the masses.
This is just one more thing to remind us that there are no guarantees of privacy. If more people knew what paper trail was associated with their card purchases and how companies sell customer/patient information, privacy would be much more valued.

That's one way to do it, but it's a fair bit of work, and never foolproof.
The other option is to make sure you never say/write/transmit anything that you wouldn't want the rest of the world to hear/read/etc.
Perhaps as difficult for some people as the former, but certainly a viable option.
Personally, I have nothing to hide.
Stupid people will be persecuted to the fullest extent allowed by law.
I think it was Newt Gingrich...and after his cell phone conversations were listened in on, he got hauled up before the ethics committe. I could be wrong, too.
I would imagine that laws are rarely illegal (which I believe means "in violation of a law")...you'd have to have either a law banning a second type of law (where an instance of the second type of law would be illegal), or two conflicting laws (in which case, both of the laws would be illegal). Now *unconstitutional* laws are a different story.
But you see, it IS being broadcast.
Scanners in Canada can listen to any frequency they can receive in addition to their intended purpose. This is why scanners always seem to have a 'weather' button. They are weather scanners..
Sprint is GSM in the DC area. Or maybe they have licenses for both CDMA and GSM, since my GSM phone roams to Sprint when I'm up there. BellSouth, which is NOT GSM in Georgia, does have GSM coverage in northeast Tennessee.
Yeah, it was a Washington (ST) rep, Jim McDermott (sp), who did it. He got in trouble by the House as well...
What license part do Cell phones operate under the US? I guess I'm of the "if you don't want people to hear it then encrypt it" routine. Security by obscurity, ala stupid laws like in the US for Cell phone conversations, are...well...stupid.
Does that then make it illegal to go around sniffing for and listening to old portable phone sets? Those aren't technically cell phones, which I thought the law specifically named as being "protected". Does it ban me using a parabolic mic to listen to otherwise "private" conversations from public areas (what is the fix for this, learn to code verbally in Navajo or Aramaic)?
Several people have posted messages to the effect that once you transmit your conversation, it's in the public domain and fair game. Several other people have also pointed out that certain combinations of hardware and conditions make it possible to accidently receive these "private" communications. These have been used to argue that you should either encrypt your transmission, or accept the consequences.
I disagree.
I do believe that there is a difference between actively scanning the airwaves, looking for conversations to listen in on, and passively having them "thrust" upon you. However, I also believe that, no matter how you come by the information, you certainly shouldn't try to use it.
Of course it shouldn't be illegal to own a TV that, under the right conditions, picks up peoples's 'phone conversations. That's like overhearing a conversation down the pub, or on a train, etc. What should be illegal is recording that conversation, or using your knowledge of it for your own purposes.
Actively trying to intercept a transmission, however, is an invasion of privacy, and should be illegal. Just because I've transmitted the conversation, does not mean that I intend it to be for just anyone to listen to. As far as I am concerned, I have made a "point-to-point" transmission from my 'phone to his.
I see the situation as being akin to that of email - okay, so I know that it doesn't go directly from my computer to the addressee's, and that it can be intercepted on it's journey there, but it shouldn't be.
It saddens me to think that the day may well be fast approaching when we must all encrypt every communication we make, or risk it being somehow exploited and used against us, or even just held up for all the world to see.
Tim
It's official. Most of you are morons.
If I recall correctly that the ultra-secret group that got together to determine the algorithm used a 32 bit key... but the first 16 digits were zeros...
That was shown by some grad students a few months back, anyway.
Good Fast Cheap. Pick any two.
As you probably remember, a couple of big Democrat party contributors rigged up two scanners and a tape recorder and followed house speaker Newt Gingrich around and recorded all of his cell phone calls. I think they finally plea bargained down to a $500 fine, and no felony charge. Of course, if you are alittle guy, without friends in the White House, you get sent to the big house.
This may be a good time point out that www.policescanner.com is still going strong.

Fuck the system? Nah, you might catch something.
A GRE down converter, a device which takes freqs
between 800-900mhz and makes them 400-500, makes
it real easy to listen to cell phones on any scanner. These can be picked up for right around $100 for most places that sells ham/scanner gear.

Not that I would like it happening to me. Actulay, stuff like this is why I still don't have one. I get jittery about my cordless phone at home...
-------------------------------------
Digital has been plagued with bad digital to
digital voice quality for some time, especially
TDMA ANSI-136 (AT&T, SBC and others). They
squeeze three digital calls into the same space
used by one analog call, so you have a bit rate
about 8 kbps. Since most systems do A/D - D/A -
A/D - D/A a lot of information is lost.
Twoo things are happening that makes this better,
better vocoders through so called ACELP and some
systems also try to eliminate the extra D/A - A/D
steps.
CDMA technology is supposed to be better, thanks
for more dynamic use of the spectrum (this is
Qualcomm phones, Sprint PCS, Ameritech, Airtouch)
GSM (Powertel, PacTel owned by SBC) has a higher
bit rate, about 13 kbps and has better vocoders
as well, so usually the queality is better.
Just short a couple of pins on the external connector on a cool new PCS phone and *presto*, you have a scanner for the unscannable PCS band. So what if the signal is digital? The phone has the circuitry to decode it. This is not an issue confined to traditional analog cellular.
It doesnt matter at all... just post the link on /. It'll be hit so much no one will be able to access it.
yeah, its a scary idea... but shouldnt we expect these things to happen by now?
Privacy? i wish.....
Stop the chinese before they have the tech. (and 100million soldiers) to try to take over the world.
Just finished a law course on this subject.
The analog cell phone user can not expect privacy broadcasting their conversations unencrypted. With encryption, one would have a 'reasonable' expectation of privacy and intercepting such a conversation would be illegal in Canada.
So...
...rebroadcasting a transmission in any form is illegal in the U.S., regardless of whether it's a cell phone or any other type of transmission IF you're not licensed to do so.
I believe...
...that *listening* to cell phones should be legal. It *was* legal at one time; the only reason it is no longer legal is because a government official got caught doing something illegal by someone listening to his cell phone call. Now, it's illegal... go figure...
Also note that listening to *cordless* phone calls IS legal (46 and 49 MHz band), unless something has changed in the past couple years since I last owned a scanner.
Originally, when radio was created, it was intended that everyone should be able to listen to anything they wanted over the airwaves. I believe this should most certainly still be the case.
However, if you use a cell/cordless phone, or other radio-transmitting device (baby-monitors... loads of fun those things are, when they're in the parents' room), you should be aware of the fact that SOMEONE MAY BE LISTENING. Watch what you say, or use a scrambled digital phone.
I would just like to point out that its still goin strong, over 2 days now. We have approx 7 mirrors runnin now. Every now and then a mirror goes down, but for the most part they're always up. So whoever thinks that the gov has caught up to the scanner is wrong, its still goin strong...............
Let me point out some very important things here:
1. There is no way to prove that those broadcasts are real. As far as you know, it could be two people faking coversations to make it sound like it is real.
2. The source of the broacast is canadian. For some reason people are blaming the rebroadcasters. What did they do? All they are doing is rebroadcasting a transmission. How do you know it wasnt a music station that just started playing cell phones one night? Are the rebroadcasters at fault for that? please.
3. Not much to talk about if the tranmission ORIGIN is in a country with no laws for that, so people try to blame the rebroadcasters cause the rebroadcast server is in the US. give me a break.
4. The government could care less, and the FCC is too slow.
Just like the cocaine that was up on e-bay. It wasnt e-bays fault they were selling drugs, they were just the innocent middle man.
keep it going!
Here in Australia, the old, unencrypted analogue cellular network is being shut down at the end of the year; for the past few years, digital (GSM) phones have been promoted pretty much exclusively, with very competitive deals. (You can get a $10/month contract, with a free (albeit low-end) handset from any carrier.) Plus, here you don't pay for incoming calls, so everybody and their dog has a mobile.
:-/
We may have idiotic politicians passing cretinous censorship laws and killing the local Internet industry, but at least we get cheap, relatively secure digital mobile service...
Actually there is a US law specifically dealing with cellular phones. It is illegal to intentionally intercept a cell phone call. Scanners that can intercept the 900-912 mhz range are now banned, but ones bought before the ban are still legal, and you aren't permitted to monitor cellular regardless of what device you have. Don't know the law's name or section number specifically, but I'm sure if you look you will find it in the federal communications code.
