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."
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.
It's Yahoo. I doubt they can't survive a slashdotting.
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.
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.
i think the reason they're comparing this to wifi is that people use wifi so they don't have to run wires. your home is already wired for electricity in most cases all over the house, but wiring it (cleanly and nicely with a wall plug) for gigabit ethernet is going to cost you.
"Chinese researchers have developed a technology to access the Internet via power lines, which is expected to rapidly increase Internet usage in China.

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. "

maybe, just maybe, you might want to read the article next time before you go on a rant. this technology has nothing to do with broadband over powerlines. this works over the premise wiring in your home or building.

Check your history books for a company called Gridcomm around the 1986 time frame.
Now if you could have a bypass, with a rather large resistor to cut back the outside voltage, then we might have something.
Actually, they are using bypass capacitors for BPL.

the /. headline is misleading. It's a LAN solution, not a broadband Internet service. The word "service" should not appear in the title.
