Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Sorry to sound like a jerk, but isn't this what you're paid to do?
TV Band/whitespace Devices are not in-between. They are "on top of" existing TV channels: 2 to 51.
White space devices work in the "white space", in the same bands as TV channels 2 to 51. FCC will not certify a device if it has any chance of causing co-channel interference.
We've done multiple studies at the University of Kansas and in order for a 802.11 basestation operating at the standard 15 dBm power to cause interference to a DTV receiver it would have to be within a couple meters if operating on adjacent channels. 802.22 (similiar signal) is the most likely candidate for using this spectrum.
Check out the IEEE Dynamic Spectrum Access (DySPAN) conference proceedings on many hardcore studies on the effects of these devices. Phil DT-6 is in the low-VHF band (2-6) which is more susceptable to various noise. This is why the FCC recommends not putting digital tv signals there. They have lower max transmission power constraints also.
Um, no. You know the "F" is for Foreign? It has never had jurisdiction over domestic communication.
Yes, I understand the "F" is for Foreign. Did you know that two "Foreign" persons can actually communicate within the US? This is considered a domestic communication because it is within the US, yet is still covered under FISA because the end users are "Foreign". So yes it has jurisdiction over domestic communication.
