Standard 802.11b access points use 100 to 200 milliwatts, not 1 watt.
So that is like, .0001 or .0002 watts right?
It's 1 watt EIRP that they are limited to. |

| .5 milliwatt?
Is that at one frequency or spread out over a spectrum? MY 1 mw 916.5 MHz weather station transmitter has a hard time getting 100 feet through the walls. Wonder what type of beam forming they are using? 1 degree beams?

| The lower radiation the better I guess
I know it's not a big deal, and that 1 watt is extremely low compared to an 1100 watt microwave oven, but considering many people these days spend most of their lives within range of one or many access points, I'll welcome less radiation. Now if they could just do the same for cell phones  |

Re: Actually
Actually, I believe 100 or 200 milliwatts, is more like .1 watt or .2 watts. Since 1 milliwatt is .001. so 100 x .001 = .1
Someone please correct me if I am wrong. |

I believe that they want to go to .5 milliwatt. This is a ridiculously low power output. Something doesn't seem right here. Perhaps these power ratings are all typo's. |

| It's using
VHF, it's using a TV spectrum that has probably not been really used in more than a decade. I don't think many devices are there except some 900Mhz cordlesses, maybe some 47Mhz cordlesses, and the like. I don't think in the UHF/VHF frequencies there is much going on right?
Please correct me if I am wrong.

| You are hereby notified that you are wrong and corrected.
VHF contains numerous services including public service, GMRS, the reviled ham radio band, broadcast, remote telemetry and tons other.
UHF is full of land mobile services, as well as the above. It is very very busy.
See for yourself here:

...and it wants its outrageous and bogus claims with its associated white elephants back.
Here's the rub; in order to have that kind of bandwidth at such a low power, the instantaneous power at any given point in the modulated spectrum will require incredibly sensitive receivers. Those are not built with common parts. Furthermore, to be that wide and that sensitive makes them very prone to interference; either fundamental or mixing products. Solving that also isn't very simple nor very cheap.
It might work at ranges of a mile out in a cornfield in Nebraska. Definetly not going to happen in New York city. |

Now if they could just do the same for cell phones CDMA technologies. Get urself a nice Verizon or Sprint wireless service.

Re: Actually
I agree. There seems to be something fishy about a power output claim that is so small that it sounds more theoretical than measurable.

actually VHF/UHF is pretty congested in most areas, 900mhz is not VHF btw...
800~900 is extremely congested with commercial and public safety systems, 800 especially (thanks nextel!)... uhf is mostly land mobile radio systems like taxi companies and lots of public safety also... things like FRS/GMRS are also in UHF...

Re: 1999 Called...
i agree, they are doing .0005 watts on vhf... i key my 6w vhf handheld and blast everyone offline for miles? 
i dunno it just dosent really add up... i dont doubt you can go miles with .0005w of VHF, providing you have very directional/parabolic antennas or something...

I'm anxiously awaiting reports that someone successfully built and tested the flux capacitor.
Edit: Apparently it's "capacitor" not "capacitator". Syllables got the best of me that time. |

Why? They transmit ALL THE TIME vs GSM which transmits in bursts. |
