Japanese Firms Claim 170Mb/s Service Via Powerline
valdean writes "Sony, Mitsubishi, and Panasonic have created and launched a new technology to transport Internet and media signals around the home via the electricity network at speeds 3x that of Wi-Fi. It's even fast enough for HDTV. The introduction is only dependent on government authorization."
I thought they just said it would be impossible to go over 100MB/s :/
"We think our technology is better."
Nothing new there...

"Who is the Greatest Man Alive?" - If you ask Gary Niger, he'll tell you it is most definitely Osama Bin Laden.
The Gay Nigger Association of America (GNAA) announced today further victory in their current program to bring about total breakdown of the AOL customer relation system.
AOL Corporate Policy has been changed after GNAA (Gay Nigger Association of America) special operative Gary Niger's constant abuse of their "secret question" program designed to provide a futile illusion of security for the mongoloids and sodomites that comprise their customer base.
The "custom question" option, allowing users to create their own question, has been removed following the efforts of Niger and other fearsome Gay Niggers from the GNAA's top secret "Black Ops" divison.
With the removal of this option, trolls are now forced to use pre-approved AOL "secret question" options when signing up for fraudlent accounts for the purpose of downloading gay pornography and meeting up with the clandestine "homo thug" underground.
"I don't know why it changed, exactly. Corporate HQ didn't tell us," said Tracy, an AOL representative. "It happened two or three days ago."
Tracy was unavailable for further comment, as she was masturbating furiously under her desk - claiming that "Ten guys were on the phone and (she) had to take them all on."
An AOL executive, speaking under the condition of anonymnity, said the change in policy came after widespread employee unrest, culminating in an incident of mass sodomy taking place in the Ogden, Utah call center.
Gary Niger and other members of the GNAA "Black Ops" division continue to use the "custom question" trolling technique with various punjabis in the Bangalore, India call center - who haven't gotten the memo yet.
Meanwhile, GNAA Command is working on the creation of new methods of trolling to work within the confines of this new standard, still flush with victory.
Nick Berg's head was unavailable for comment at the time of this release.

Asked why the three companies came up with their own technology and risked yet another format war in the consumer electronics world, Chmielewski said: "We think our technology is better."
Translation: We patented our version. Ka-ching!
Learning HOW to think is more important than learning WHAT to think.
that has to give the ok. If it was the Chinese government we never would have heard of this development in the first place.
That is 170Mb/s when tested over a dedicated power line... The speed will bottle-neck all over the network when used with an unknown number of users. But it is good to know that a direct dedicated point to point line can handle such speeds. Means, depending on the architecture of the network and the locations of the end points the users could see as much as 10Mb/s of that each.
Electrical power lines are not surrounded by a ground shield. I hope they came up with some security to go along with their high-frequency data mover.

HANOVER, Germany (Reuters) - Three Japanese consumer electronics giants have created a new technology to transport Internet and media signals around the home via the electricity network, Panasonic said on Thursday. Sony (6758.T), Mitsubishi (6503.T) and Matsushita-owned (6752.T) Panasonic have set up the SECA powerline alliance.
Desktop Duel
Preview the major OS updates from Apple and Microsoft. Is OS X reason to switch? Plus, the latest Linux goods.
They have developed a system to transfer 170 Megabits per second of data through the power lines of a home, Panasonic researcher Ingo Chmielewski told journalists at the electronics trade fair CeBIT.
He said the technology is already available and introduction depended on government authorization.
The speed is three times faster than wireless technology Wi-Fi and is fast enough for high definition television signals. Unlike wireless alternatives, the powerline technology performance is stable throughout the home. SECA will compete with existing technology from the HomePlug alliance of 50 companies, including Japanese group Sharp (6753.T). The two systems are not compatible.
HomePlug's current standard is only 14 Mbps but it is thought to be working on a faster version.
Sony is also a member of HomePlug, according to the consortium's Web Site and it was unclear if it would be part of both. Sony was not available to comment.
Asked why the three companies came up with their own technology and risked yet another format war in the consumer electronics world, Chmielewski said: "We think our technology is better."

With that speed, it would only take around 1/170th of a second till the first MB of "... IN JAPAN!" memes hits /.
I first saw network over home powerline products quite some time ago (probably not at these speeds, however). I seem to recall the usual issues about dirty power, the fridge kicking in, et cetera et cetera. Does this deal with those any better?
The World Wide Web is dying. Soon, we shall have only the Internet.
The Internet was originally intended to be a communications network that the American Department of Defense (DOD) would use in the event that the Russians destroyed a significant part of the military communications network. I suspect that the DOD will find this new Japanese technology to be quite interesting.
Fortunately, the Japanese developed the technology before the Chinese. So, the Western world is safe -- for now.
Vietnamese people are backstabbers. Don't trust them, ever!
It gets high speeds inside the home, enough for HDTV, but why would I want to broadcast an HDTV signal through my home's powerlines when I can get it just as well through normal cable or satellite?
Japan begins to take away the last great thing America has -- innovation and creation of new technologies.
Great! Now, we should take a hint from the rest of the world and follow three easy steps:
(1) Wait for [Japan] to develop new, high-speed-over-powerline technology.
(2) "Borrow" technology for use in American homes.
(3) Profit!

Does this work like cable?
Cities in Japan are densely packed with business and residential users. Sharing 170Mb over the densely populated region may not be so advantageous (there you probably have a better bang for yen with DSL type networking). However, it'd be great for those who live in the remote area and have to do a 2+ hour commute every day. With the huge bandwidth, they can really telecommute. That is the kind of action that Japanese firms need to make to alleviate the social problems going over there, I'd guess.
Yeah, I know, I may be just a full of it.

I'll take 3. I wonder how much this service is per month? And I wonder what the distance is on this deal, if it's like DSL (a short range) or if it's like dialup with its virtually infinite distance.
Will this technology induce extra RF interference in other appliances? It was considered a negative possibility everytime Broadband over Powerlines has been mentioned in the past. Does being localized to a home reduce that? Is it actually localized to the home or can it spread from a home to outside powerlines then onto another home?
*Imagines the next form of "War-Driving"*
From what I've learned, Japanese engineers have the enviable ability to invent something to fit their needs, even though the development cost would have to be recouped in sales. The stories I hear about developers here in America tell tales of requirements of immediate or near-immediate profits. *coughCarlyFionacough*

Do you want to be surrounded by those kind of EM emissions? Low frequency EM is known to be bad (tm), using your house as a big emitter seems stupid to me.
You fail it. HAHA @ FAILURE!
Why not just introduce a service using live vipers and chunks of broken glass? It couldn't be more hazardous than letting common users fuss around with power lines.
Household power wiring is not designed to be an RF transmission line. Are they going to follow the path taken by BPL and Homeplug, that is to shit all over the HF spectrum since nobody important is using it?
Mea navis aericumbens anguillis abundat
It's Yahoo. I doubt they can't survive a slashdotting.
Why not just say x times faster than DSL or Broadband? I think more people understand those kinds of data rate comparisons. And it's the same type of physical layer.
I don't get it.
Well, it's Japan and they like many types of pr0n... cartoon pr0n, bukkake, schoolgirl pr0n...
Get your Unix fortune now!
This isn't the same ol' "Broadband over Powerlines" that we've seen before. We're not talking about an ISP service here. It's a local home network, like a wireless hub. You'd still need to provide internet access. Plug your net connection into one socket, and your terminal into any available outlet in your home, et voila: Internet access anywhere in your home an outlet exists. No worries about walls blocking the signal. The obvious downside to this being, you have to be leashed to something to maintain your access; provided they don't make it wireless for "the last foot". Of course, that would nulify much of the usefullness of such a network.
If they implement this here, kiss your 2 way radio's good-bye. The radio interference those large powerlines give off when they are all jacked up with Broadband is nasty.
Authority questions you. Return the favor.
I have three major concerns with this.
1: Noise between your network and your neighbor's network that are both on power lines coming from the same transformer on the pole, with no transformer inbetween. 2: Noise on the mains from the network equipment interferes with your power-level sensitive equipment. 3: Noise on the mains from equipment (possibly malfunctioning) on the mains that interferes with the network equipment.
Video Production Support
I knew you could.
Just one more thing to run down the same pipe.
Before long, everything we have in our households which involves a form of communication will run through a common pipe and a major dependency will present itself. One well-placed "accident"...and...I think it's obvious.
The only self-protection (powerwise) is fuel cells capable of supporting your house[1]. But that only presents an opportunity to prevent a blackout in your house. (and prevent a brownout because you can flush your toilet) Does that mean you can't communicate? (seriously) - would the fact you have some form of power prevent you from sending any type of signal across the same lines?
[1] My vision is instead of keeping just one at your house is to avoid a single cutthroat dependency is to create a minigrid with a handful of your neighbors. If you or your neighbors have a fuel cell power outage, you can stay afloat until repairs can be made.
Yeah, we wouldn't want anyone plugging stuff into the power outlets, would we?
Oh wait...
I will not RTFA.
I don't need to RTFA.
I already know this technology is bad with out RingTFA.
So, no, I will not RTFA.

If it is from Japan, there has just GOT to be a robot involved somehow.

I love reading stuff like this.
All I can think of is the bosses of our local telecomms incumbent reading this, instantly loosing control of their bowels, the splash of the explosion showering their faithful lieutenants in gooey excrement.
I'm in New Zealand. We pay $70/month for 2mb down 196K up. Its sketchy at best as interleaving pushes pings to about 70-90ms. No unbundling of the LL, and a government that takes it like the Goatse guy from the incumbent, better service is a far off dream.
Please, dear jesus, let alternatives like BB over powerlines work.
In post Patriot Act America, the library books scan you.
Some time before the summer rolls around im supposed to get internet threw my powerline and i live in the us. Unfortunately im going to get those kinda of speeds
do you seriously think yahoo news is going to get slashdotted? no, i didn't think so either.
Geeks getting 1 terabyte of porn in less than 1 minute. Yes, it really is a pathetic world we live in.
It is important to note that this technology would only work inside your home. It would never make it past the transformer at that speed, if even at all. Transformers, by their very nature, kill off any signal that would be sent down the line. Now if you could have a bypass, with a rather large resistor to cut back the outside voltage, then we might have something. Since that's not very practical, don't hold your breath.
For home networks that wanna, say, stream HDTV from a media server with something like MythTV, that sounds pretty sweet.
bash: rtfm: command not found
Now I have to firewall my exterior power outlets?!
Great!
So, power lines are to become the antennas that
broadcast new interference that can make use of
the HF bands impossible for Radio Amateurs and
others, alike...
That's like creating large waves on all of the
bodies of water that amateur Sailors use for
their happy hobbies.
Who wants such intrusive & offensive technologies!?!
I - for one - wouldn't... Say NO to BPL (ie,
Broadband over Power Lines) - even for the
Japanese - ie, if it has to displace so many
happy, helpful, self-educating radio hobbyists.
Would YOU want to support such a technology?
"'not even if it helped the Space Program"
"Chinese researchers have developed a technology to access the Internet via power lines, which is expected to rapidly increase Internet usage in China.
1 29 _89568.shtml
Developed by the Fujian Electric Power Testing and Research Institute and known as 10MBPS digitized power line (DPL) the technology enables computers to access the Internet via an USB power line communication adapter.
With a modem, it also allows data communication to be made via a power line between computers and any electrical equipment, such as computers, TV, DVD and even heating devices, making remote control easier.
Lin Han, president of the research institute, said that the technology is superior in speed and stability to similar technology in foreign countries . "It works well with a voltage range from 180-240 volts, with a maximum data transmission speed of 10MB per second.
According to the institute, the technology is now ready for commercial use. When mass produced, the special modem required will cost around 500 yuan (60.24 U.S. dollars), which is about the same cost as conventional modems.
The institute still has to go through a series of formalities before commercializing the technology. "

When there is a disaster, and they need to use ham radios, I hope they enjoy the interference. Sad that they are not remembering that lo tech sometimes is needed - and this interferes with lo tech radio wave transmissions.
now, that will finally kill my x10, already barely working due to interferences.
will have something to say about this.
by TheSpoom (715771) Uncaring Linux user here. I have nothing to add to this but please continue. *munches popcorn*
so my walls that i sleep near will be buzzing with more data emitting more radiation then my cell phone now.
A "Ham" operator I've known has been involved in petitioning against licensing technology to use the power lines for communication. He says it bleeds badly into the amateur radio bands; as if amateur radio doesn't bleed into any receiver not using any *pass filter.
In other new, I can hear faint transmission signals from John and Ken, Dr. Laura, and Rush Limburger on a land-line telephone if I concentrate enough. And worse, this neighbor of mine is adamantly against my tele-phonic receptance of slashdot servers; the echo is toooo annoyying they say.
I think everyone should be communicating be opening a can of Alphabet Soup, arrainging the encoded message, and consuming the information. Much more efficient and all. OT: And my Krishan brother says if he was president that he would make a law that anyone getting a Driver License may only use a miniature motor-scooter to ride for daily commuting to a worksite and back.

This was technology that Europe invented (in a tweeks different alternate form). It was killed because it was found that it interferes too heavily with terrestrial radio communications. The internet over power lines then shifted to North America. A great way to cover "the last mile", internet over power lines!!! -except that it was eventually killed because it was found that it interferes too heavily with terrestrial radio communications. Now we have HEY, A GREAT NEW TECHNOLOGY, INTERNET OVER POWER LINES!!!!!!!! Wanna bet that it gets killed because of 1. Very heavy interference with terrestrial Radio communications and 2. Complete lack of security because your neighbours can pick up your data signals on their tv, radio, cell phone, pager, walkie-talkie, cordless phone, baby monitor... ???
...at least if T3 servers can upload as fast as shown here.

Stop being so arrogant. Yahoo isn't some feeble online company with a penny-pound server. It's going to take a lot more than a patrol of online geeks to "Slashdot" one of the world's largest online corporations.
My digital rights don't need management.
hey stupid, if there's a disaster and the lines are down, there won't be anything to cause interference.
You only need an adapter.
Sheesh, you know that a disaster can be localized right? If they need to communicate across an area that is untouched by the disaster (ie everything is still running) to an area that has been decimated (ie nothing is running) - you are still going to have trouble.
It is called a tesla coil. There is various folklore that in 1878 or something, electrical distribution to homes could have just as easily been done using tesla coils as wire. Look up the person Graf Von Tesla (sp?).

Muslims walk out of Dell plant in row over sunset prayers
AP , NASHVILLE, TENNESSEE
Sunday, Mar 13, 2005,Page 11
Thirty Muslims walked off the job at a Dell Inc plant after alleging the company refused to let them pray at sunset -- the latest dispute over prayer between an American business and its Islamic employees.
The Muslim workers, who were packaging Dell computers through a temporary labor agency, are taking the dispute to mediation, both sides said on Friday. Most of the employees are from Somalia.
Abdirizak Hassan, executive director of the Somali Community Center of Nashville, said the workers walked out of the company's Nashville plant last month because they were not allowed time for prayers.
The question of how to integrate Islamic prayers into the US workplace is becoming far more common, with many companies using a "tag out" system to accommodate the prayers, said Ibrahim Hooper of the Council on American-Islamic Relations. The policy allows workers to step away a few at a time for sunset prayers.
Muslims are required by their faith to pray five times a day. Most of the prayer times are flexible, but the sunset prayers must be said at dusk.
Byrne Mulrooney, a spokesman for labor agency Spherion Corp, said the company was still trying to determine what happened. He said the Fort Lauderdale, Florida-based company has a good record of accommodating its Muslim workers.
Dell spokesman Mark Drury said company officials are looking into the Feb. 4 incident. He said the Round Rock, Texas-based company has a "tag out" policy, and wants to know if Spherion was following it.
The mediation will be handled by the city's Human Relations Commission. Kelvin Jones, executive director of the commission, said his staff has interviewed the workers, who are expected to file formal complaints by early next week.

Of course that's also that many fewer people being exposed to the ads that helped pay for everything that went into the article being written and posted at the original site in the first place, but we're all too cheap to buy any of that stuff anyway :-)
I see even classic Slashdot is now pretty much unusable on dial up anymore.
Ok here is a theory. With IPv6 supposedly the next big thing, do you think that this might aid the introduction of new internet capable devices. Considering the new internet technology supports 430 quintillion addresses per square inch. So, why not use every bit of wiring already in existence in a house? Yeah it may only be good for in the house, but isn't that good enough. No it's not for the LAN games of the future.
Would be nice to have a chip in every light bulb. No need for a special socket, or rewiring, just buy the latest light bulb technology. Oh, you'll see it, I'm sure it will be in the stores some day. Does it really matter what this chip does? It could make the light bulb turn on. But why not throw a chip into everything if you can. Why not make everything better than it is now? It wouldn't make life any better, but who the hell cares when you got all these new fangled contraptions. If all it took to have a wired connection was to plug in the power then it would be more feasible that devices would take advantage. The current proliferation of technology certainly points to this possibility.
That is the American 110V version. The Japanese use other voltages.
Anyway, the BEST one you can get, uses 660V 3-Phase. It works even faster.

It totally destroys abilities to use HF frequencies that are vital to long distance communications.
I have reason that you approached the situation in bad faith; have you ever considered that HF use by radio operators is a lawful activity slandered as causing damage to future interests of FCC-subsidized commercial communication future interests invested by corporations? Put that thought in your pipe and smoke it.
Amateur radio operators put alot of time, effort, and money into their hobby, and when something like this comes along, that can cripple them, who can blame them for fighting against it?
I don't slander lawful and courteous use of God's radio-waves as licensed (immoral activity). Your deem of a "Radio License" as "Hobby" falls on deaf ears to lawful men that do not engage in commercial press; limit your operation to freedom of press. When you slander and attempt to convert your actions to licentiousness by confessing the subjective words commercially into merchant domain, and bear witness maliciously against people with lawful use of radio-waves, it does not rest any attempt to censor or waive such as reasonable seizure of duties as rights subject to waiving as privileges and timely shared or equal use; the people != corporations.
FCC conducts religion; it is a corporation holding a testament given by its corporators. If you estoppe your slander of converting lawful activity into legal/legitimate form or licentiousness, then you'll have no difficulty exercising such special activities and common rights to foreward your happiness.
Try it on for size: rid your communication by the mark of the beast by announcing a THIRD-PARTY INTERFERENCE into a transmitting utility not blessed by the FCC. Kings endure courteous outcome; why the license?
It was just last week that my brother a prince retourned from a "boat show" convention with a foreign tributory title of nobility in the ill-form of a "Junior Fishing License"; You imagine that there are wicked religious fanatics and enthusiasts slandering and unlawfully converting the duty to timely exercise domain over God's fish equate to a "game" or "sport" and not as a lawful and righteous activity in the course of events to survive and preserve the future of fish; but I say not to acknowledge such conspiracy until it becomes worthy of a rebuke and necessary correction when it becomes a force in bad-faith contending default to assumed competitors by vandalism and mischief from enforcement "officers" and the like "COPS".

While you might only need 19.5Mbps, that assumes only one channel/TV, and assume you aren't do anything else on the network. Most homes have to contend with multiple TV's, plus little Jenny video chatting with her friends, and little bobby is downloading MP3's over P2P, while mom is using Vonage to make a call. You need a bigger pipe to support all of that.
The real question that now needs to be asked is what sort of QoS is provided to insure no dropped packets for VoIP and HDTV?
I want them to figure out how to power my microwave from my television cable line.
Why?
Because in the future, you will get your electric bill from your cable company and your internet access from your electric company, that's why.

The strange part about the article is.. WHO are theese HomePlug consortium guys? I mean, cmon, 14MBPS?
;)
Microlink had WiFi speeds for over a year now, announced 85mb/s over power line this year on cebit (afaik). They also provide various other modes of transfer (usb and audio for example)
More info here: (sorry, german page is updated, english not so much)
Products page
85MB/s plug
seamless router (tell me you knew about the ethernet/powerline)
Looks like HomePlug will be one of those "projects" aiming to keep back technology for profit.
There is another thing that gnaws at me with this technology. With existing power infrastructure trough the house, this kind of tech could be used as concealment for more vital computer data.
Everybody who's been raided anytime for warez or whatnot (*AA), can appreciate from where im coming. I dont remember people taking Hi-Fi systems, speakers, monitors (ok, they might have taken those), however I do remember them taking everything "computer" in the line of sight. only problem is if they take the adsl modem/router too, that can be a bit tricky to replace.
Usually you got power pretty much everywhere but across the floor, and sometimes its pretty ouf of sight, like some boards on the ceeling. Would make a pretttty nice place for a near silent server with a couple of TB incriminating data
If nothing else, you can hide a noisy box far away this way if you dont have an ethernet infrastructure in your house.
Only Russia has the time machine technology that could be used to travel to three years ago to retrieve this technology-- and they aren't interested in sharing.
Irritable, left-wing and possibly humorous bumper stickers and t-shirts
It will be most interesting to se how they plan to evade the EU EMC directive on this one.
Spewing HF and UHF energy out on the power-line is something you can't do in a residential context. (Just think of the emissions being transformed backwards through the power grid.)
the /. headline is misleading. It's a LAN solution, not a broadband Internet service. The word "service" should not appear in the title.
if the power wiring is not segmented (for fifty users, it will likely come in two to six easily RF-separable sets of circuits, typically one set per floor), if each of the three phases are RF-connected and not filtered (unlikely), and if every single resident uses the service.
In real life and assuming reasonable terms, about half of your tenants will take you up on it; the three phases will be separable, and your fifty residences will be in three floors of seventeen units each. This gives you six residences per phase per segment, or three actual users per phase-segment. More likely this would happen to a block of 600 units on five floors with about 30 actual users per phase-segment, or about 6Mb/s each.
Then we add the killer term: on average.
If two of those users are watching the same video feed, they share 12Mb/s for it (and with a compressed video stream would be struggling to use more than about 2, thus freeing up anouther 10Mb for the others). If another happens to have their PC off while they're at work, their 6MB is 100% available to the other 30, ie, 0.2Mb extra each (pecking away at email, IM, IRC or HTML browsing will also use close enough to zero bandwidth, out of 6Mb, for most accounting purposes).
Got time? Spend some of it coding or testing
marketing was near as thick as AOL's yet I only know one person who ever installed any of the X10 stuff.
Is there really any need for 170mbps over the line cord?
Um, new? Is this at all similar to what Cinergy (and probably others) has been experimenting with since March 2004?
Well I heard of this a few years ago now and it does seem interesting. But i seem to remember there being some problems with this technology and AM radio, in fact i think a couple of years ago there was so much interference that AM is doomed with this. I dohope they have sorted this issue. How else are we going to be able to keep up with the cricket otherwise.
There is no way I'll be using this technology in the near future after having 3 seperate computers crap out on me at my parents house in large part due to dirty power throughout the house. Can anyone tell me what sort of effect this will have on unprotected appliances in the home over a long period of time?
Flamebait??? Rude, yes. But also funny. Do the mods have no sense of humor today?

can carry your voice. That doesn't mean that it is the greatest technology in the world. Personally, wireless is the way to go.
I can do 100Mb/s over ordinary CAT5, and it costs $60 for a 1000' box. Why the hell would I want to use the electric wiring in a home for networking?
Heres a message for them - "Go back and figure out how an ISP can use the outside wiring to deliver last-mile broadband, bypassing both the cable and telephone companies. Then you might have something newsworthy"
Many HAM's have portable stations installed in automobiles - not dependent on anything that a disaster might put OOC (eg, electric utility).
How short our memories. This idea pops up every few months. Somebody gets the idea that because wire is wire, you can piggyback twisted-pair ethernet like signals over the power wires. And you can. In the lab. With no surge surpressors on the line. No light-dimmers. No Touch-lamps. No taxicab radios in use nearby. and 500KW TV station within 5 miles. No subways or streetcars closer than a block. No biker bar nearby. Works about good enough to convince the latest incarnation of venture capitalists. Yep, works real good.
Just what I always wanted, yet another source of radio spectrum noise. No small issue, we're talking disruption of a service that most people aren't even aware of and is insignificant until there is a major disaster.

There are current Powerline products out there.
Though the speeds are pretty dismal (up to 14mbps) they work WONDERFULLY in homes in which wirelss is simply not an option, no one cares to transfer large files between computers, and no one wants to poke holes in walls.
Everyone is right about the security problem, though Netgear, for example, ships a utility that places a password on the connection. I've honestly never tested it in my line of work, but it purports to stop rogue powerline adapters from plugging into open outlets and gaining Internet access.
I, for one, welcome our Sony/Panasonic/Mitsubishi-170Mbps-Powerline-Tech overlords.
If Nalgene water bottles are outlawed, only outlaws will have Nalgene water bottles.
How else can I use my neighbor's service to download pron and HDTV?
haha
This is not a revolutionary new idea. It's been discussed for several years because of this problem. Also, please note from the article this is not a replacement for you cable modem or DSL (or verizon fiber). It's a replacement for your wireless router or cables draped down the stairwells inside your house.
I'm really enjoying these trolls about the threat of China. A new trend or had I missed this one? :)
:P
Keep it up!

I've played around with ehternet over powerline in the "typical" Japanese residential environment and I'm not impressed.
You would be surprised and shocked (no pun intended) at how many folks the Japanese manage to squeze onto a single transformer. You'll get some really weird shit happening that harkens back to the day of worring about the physical network span of your thick-net coaxial ethernet cable.
I'll belive the corporate press release (*EXACTLY* the same as an American corporate press release) when a usable product materializes that will work as advertized with 30% of the folks in my 7 story mansion have it installed (along with the other 10 buildings of similar size that all run off of the same transformer).
Internet over powerlines has already been done in Ontario and in 2003 Quebec was testing it - they prob have it now as well...but the speed that this new LAN offers is quicker.

Hydro-Quebec to test internet over power lines
Last Updated Mon, 24 Nov 2003 11:04:19
MONTREAL - Hydro-Qu?bec is planning to offer high-speed internet service over its power lines to compete with similar services from cable and telephone companies.
The utility already uses signals over its power lines to control stoplights, but now it wants to adapt it to offer internet access.
Some experts say such a service could be up to five times faster than high-speed cable internet service.

No, no, no. The signals do not go outside the home. They're talking LAN not WAN. The signal strength of the transmitter is probably in the order of a few milli-watts - don't panic, it won't interfere with some ham radio operator 2,000 miles away (maybe next door, the the carrier frequency is going to be in the 2-9 GHz range, so unless he is chatting with someone on Venus, it probably won't hurt). I would imagine there will be transmitters/receivers plugged into the power outlets that have different channel settings on them. If you are getting interference from your neighbor, then switch channels. Those same transmitters/receivers will filter out any powerline spikes/appliance cycling/etc. Nothing really new here (this technology has been around for many, many years), just more bandwidth. I worked on a design back in the late 70's to send data over the power feed of a borehole navigator. Been there, done that. Remember X-10? Same principal, but more bandwidth.
Perfect is ALMOST good enough.
muslims and other slimes can go fuck themselves. if a business doesnt want to subject itself to this bullshit, fuck the muslims and everyone else who cant live by the rules.
employment isnt a fucking right, and a privledge that an employer can grant you if its feels like it.
this will only help to secure more hatred for them. they are annoying, poorly washed and evil.
long live normal secular peoples who respect work and good living.
Spanish DS2 PLC chipset developer provides more than 200 Mbps:
"The DSS9XXX-based series of PLC modem devices share the same physical layer characteristics, allowing seamless integration of access, in-building and in-home media networks. Advanced OFDM modulation provides the ability to cope with all of the powerline channel impairments while using high-density constellations that provide a throughput of more than 200 Mbps."
