Motorola Plans Wi-Fi Cell Phones
Otto writes "This AP article over at CNN talks about Motorola's plans to create a cell phone that can seemlessly switch calls between cell networks and VoIP over WiFi, when it sees WiFi available to it. Thus reducing on call costs. Personally, I think it'd be cool just to have a cell phone that could use my own WiFi at home and be cellular when I'm out in the rest of the world."
How long would it take for someone to write a Windows program that made it as easy as executing it to listen in on people's conversations over Wi-Fi? Lots of public hot spots don't use WEP, you know.
Now cell phones will be wireless too!

The article talks about all these low cost WiFi hotspots. We have a local college where you must be a student or faculty, a Borders where you can pay T-Mobile $30 a month, and that's about it. Or maybe they are talking about crusing the neighbourhood looking for unsecured home wireless connections? Hmmmmm!
Here's a possible extention to this idea... allow the participating WiFi sites to announce the availability of a VoIP link back to the cell-provider's network, basically allowing anybody who roams by to borrow the WiFi as a mini cell tower, and letting the hotspot owner pocket a few pennies of savings on their bill for helping the stranger.
This could become a low-cost way of extending a cell network into rural areas where it's hard to put up a traditional cell tower due to zoning hassles, but virtually anybody could mount a WiFi antenna on their roof next to their TV antenna.
Isn't this going to cause problems say when you walk by a company with lax wireless security and you unintentionally connect to their network and steal their services. Not saying I care but some one has to.
just because your a schizophrenic doesn't mean people arn't really out to get you
Yes!
Hopefully this would finally be a way to escape the "at-home dead zone" when I try and use my mobile down in the basement and I can get rid of that silly land-line once and for all!

Is a cell phone that you could just plug into the wall when you're at home, and it would get both power and connection from there. In fact, I'd imagine someday people having one cell phone in their pocket, and maybe a "wired cell phone" in their homes, which would run off wall power and be more reliable since it wouldn't need a radio signal.
I wonder what kind of protocol it could use.. maybe firewire protocol over wi-fi, converted to frames that could be sent over a wire like ethernet. There could be some kind of power-over-ethernet to supply it with DC. Then it could run out to the street, where it would go into a tower and be converted into real wi-fi signals, except encapsulated in GSM data so it could use the existing cellular infrastructure. No that's no good, coverage is spotty. Maybe satellites could be involved. Could be expensive. Maybe it could run over DSL? Hey there's an idea!
Modern technology allows so many simple and elegant solutions to today's problems!
Gotta run, I'm working on my latest invention: a way to take ebooks and permanently output them onto sheets of paper. I think this will revolutionize the ebook industry!
Yet another way for people to snoop my phone conversations. I seriously doubt any encryption you could implement on a mobile phone's processor for transmitting voice would be more than trivial to crack. SSH yes, mobile banking, yes, but no way is there you can encrypt my voice conversation.
Suddenly the concept of wardriving has become a lot more interesting. "VoIP wireless hotspot" suddenly becomes synonymous with "Blackmail hole".

This could seriously hurt cell phone service providers. With the growing popularity and widespread adoption of wi-fi everywhere, I wouldn't see a need to even have a provider. This is of course the phone is able to seamlessly jump from one wifi network to another - but then comes into consideration of reliable signals yadda yadda... It was only time for this to happen.

Cell providers already have "mini tower" equipment they can set up in their stores to assure that they never have an embarassing dead spot at their own retail location. They even set those up at business sites to assure an otherwise uncoverable corperate campus gets hit with signal.
I guess it was only a matter of time until they converted such units to a home game model...
You missed the point:
The last people who want this to work are the big carriers.
(looking up IDTs stock price...)
ring tone downloads at 54Mbps!
Just FYI, Ericsson and others have had dual-mode DECT/GSM phones since the late 90's and adoption has not been spectacular.
These phones allow you to roam indoors on a DECT local digital connection to your landline and roam outside (or in large buildings) with seamless handover between DECT base stations. They also doubled as GSM but I don't think the handover was automatic, see:

I don't get it at all. While I think it's a great idea to have WiFi phones on a campus (I had a crazy business plan for that 5 years ago!), I just don't see the point in the rest of the world. If I have a cellphone, I don't need WiFi. And unless WiFi coverage is ubiquitous, I wouldn't want a WiFi-only phone. I have a Treo 600 with unlimited data & 800 peak minutes a month plus unlimited n&w and mobile 2 mobile & phone insurance. I pay about $34 (a really good deal, but anyone could get that deal for $40-45 with some work).
The point being, I ahve absolutely no need or desire for WiFi for either data or voice. A fat pipe would be nice for streaming audio, but I could live with a lower bitrate. Unless Motorola can make this 100% transparent, it will be such a colossal & immediate failure that New Coke, Audrey & Teledisic will look succesful by comparison. If they can make it 100% transparent, I doubt it will have any application outside of buildings with awful cell coverage; it just doesn't make any sense as a moneysaver, since most providers (e.g., SprintPCS) have excess capacity now.
Actually a lot of cell phones have huge processing power that goes totally unused, not to mention that this would be on NEW devices. Think your 10 day standby time is good on a cell phone? There are wireless digital handsets in use in hospitals and universities that get 70 - 80 days of standby (even 150), why? Because they don't have the fancy processors and memory modern game play'n, websurf'n voice dial'n cell phones do. When you're sitting on the can playing Push-Push you're using more CPU than it would take to compress a voice stream.
Encrypting a stream text or voice doesn't much matter it's about data rate not content, when you get a lag in an SSL terminal in virtually every case it's not the cryptography that's causing the delay. Modern public/privet key cryptography scales pretty well for various data rates. The rate of your digital voice conversation on your cell phone is pretty low (which is why it sounds like crystal clear 8 bit crap).
Not to mention that you'd only need to start a new encrypted once and a while (to your provider not the WiFi Network) and NOT every time you make a call. Who cares if someone listens in on your traffic on the WiFi if it's just gibberish going to the Cell company any ways? Or did you think by any means your cell company would let you move to VoIP and connect to anyone OTHER than them?
Puleeze these people practically invented sinister strangle hold service.

A simple passive repeater is no problem to install in a dead zone such as a basement.
A high gain antenna on the roof pointing to the cell tower is connected to an omni antenna in the basement. This provides signal in the dead zone.
A small dish works great as it can be pointed to the tower providing high signal strength to feed the basement antenna. Be sure to use antennas cut to the freuency your cell provider is using. Use a large diamater low loss cable or all system gains will be lost in the first 15 feet of the cable. In extreme cases, eliptical waveguide may be used but it greatly adds to the cost of the project. To prevent cable loss, keep the cable as short as possible. Many houses have high attenuation because of masonary walls or aluminum backed insulation in the walls. A roof mount dish coupled with about 6 feet of wire to a ceiling mounted antenna are sometimes all that is needed to couple the signal from outside into the living space covering even the basement with good signal.
The truth shall set you free!
Is there a market for a device like this? Am I the only one that thinks that voice over IP/WiFi is complete crap right now? I tried Vonage for a week. Hated it.
Why? Because there were gaps and pits in conversations... awkward silences due to missed packets... missed incoming calls... et cetera. Don't get me wrong... I think the tech has promise, but as it stands right now, VoIP is not ready for primetime.
Furthermore, the broadband providers need to get their shit together, too. DOCSIS nor xDSL are very reliable and I use a relatively respectable provider (RR). It seems that the move to VoIP is being based more on trying to save a quick buck, for customers and providers alike, and less about QoS, rock-solid reliability, and future practicality.
I mean REALLY... what good is side-stepping the CLECs in the name of lower costs when they're the ones we ultimately have to route calls through to call POTS lines from time to time?
Look... I know there are some of you out there who really love VoIP, but I'm worried that five years down the road, the teleco infrastructure will be worse off. Economics are slowly encouraging people to move to an ad-hoc network which was not originally designed to do what we're asking it to do... handing telephone calls. This same network is polluted with worms and viruses. Do you think customers want to lose their dialtone because some asshat decides to release a Windows exploit?
But then you could use the GSM signal as backup! Right. Now what about the people living in rural areas? They count just as much as the rest of the country.
I could go deeper, but I'll stop unless someone encourages me to add more.
