| More Power, baby! The amount of power necessary to illuminate those LEDs (and at at BPL frequencies far above 60 Hz) would certainly make the entire room a very nice RF radiator.
Yeah it's possible, just like your IR remote control transmits data, but there certainly is something odd with this entire concept.

| Re: More Power, baby! It's a computer simulation. No actual LEDs were harmed in the drafting of this press release...
Kavehrad will detail the Penn State system and its performance in simulation in a paper, "Hybrid MV-LV Power Lines and White Light Emitting Diodes for Triple-Play Broadband Access Communications," at the IEEE Consumer Communications and Networking Conference in Las Vegas, Nev., Tuesday, Jan. 10. His co-author is Pouyan Amirshahi, a doctoral candidate in electrical engineering.

| "In the Penn State system, white LEDs are positioned so that the room is lit as uniformly as possible. Since the LEDs are plugged into the room's electrical system, broadband data, voice or video delivered via the power lines can piggyback on the light that fills the room to reach any wireless receiving devices present."

| Re: Rx - Yes / Tx - ???? I would imagine that the LEDs are pulsed (actually, "occulted", meaning they're mostly on with brief periods of being off) at a very high frequency that enables communication, both from the infrastructure to your portable computer and (during predetermined "off" cycles) from your computer back to the room's infrastructure.
LED's already operate at very high frequencies to drive fiber communications, so some of the same possibilities probably apply, though perhaps at a lesser capacity as the "white" mixed spectrum LEDs are usually a generation or more behind the longer wavelength, lower frequency red LEDs.
In any event, as most people can't even see the flicker of a 60 Hz fluorescent bulb, nobody's going to notice any flicker above a kilohertz, much less something in the MHz or GHz ranges....

| you connect a incandescent lightbulb to your pc or that pc monitor has a frequency, yeah right? Or maybe upload is over a dial-up lline heh
So every room would have to have a receiver built into the lighting or maybe the pc transmit out the power cord but then why not just run it over power lines without the lights.
I think this is bogus. | |

Rockville, MD | what the article really says "...its performance in simulation..."
Once we improve the simulation and when those leds become available in 7 or 8 years, we might have a working, commercially viable system in about 10 years. | |

| but problematic.. No nighttime broadband? Why not use wifi or wimax once inside the home? If gigabit were possible, why wouldn't it be implemented already. It could help finance the rebuilding of the power grid, making it more reliable. Would certainly piss off telcos like sbc and bellsouth who can't or won't upgrade their networks fast enough. | |

| Just Me Maybe it's just me, but I seem to have read about 'Gigabit' internet before. Only the article turned out to be a separate way of creating a gigabit LAN and had nothing to do with connecting to the internet.
This seems to be such an article. They may have (theoretically) achieved those speeds in a simulation based on a wireless LAN they built (possibly within one room or a building). This somehow does not seem to prove anything about increasing bandwidth over real-world power lines through BPL. Falsely-led hype?

This somehow does not seem to prove anything about increasing bandwidth over real-world power lines through BPL. Falsely-led hype? Indeed. Home power wiring is much different from overhead power lines outside. Too many people confuse in-home BPL with Internet access BPL. They often use the same technology and chipsets, but it's apples and oranges when it comes to bandwidth capabilities.
The previous Penn State study/experimental model on BPL released last year showed that BPL could achieve speeds of 1 Gbs under ideal conditions, and you'll often see people saying BPL will beat out cable and dsl due to this. However, if you applied the Penn State BPL model to submarines, they could go at speeds that would break the sound barrier....if you eliminated the water and put wings and jet engines on the submarine  | |
