what a second...

i thought the cable tv networks were all fiber? RF can't interfere with fiber optics. i think i'm being lied too... .

this is such BS. they perform tests and come up with results that, surprise, support their view. if it really does interfere, then publish a couple papers to a IEEE conference, journal, or similar. i'm just looking for some peer review done by a third party.

maybe i haven't read enough of the complaint PDF, but it does strike me a little odd that it was more of a test of "lets do our best to try to make the picture fail" than "hey, let's make a 'whitespace device simulator' and see what happens to the picture". this is based mostly on: using a directional antennae (i'd expect the antenna for a whitespace device to be omnidirectional unless you are far far away from an access point), the simulated whitespace device is just additive white gaussian noise (although it may be similar, couldn't they ask google/microsoft for some basic specifications on their whitespace device? this may help prove or disprove the cable company's view depending on many factors). I also get the feeling of there some 'smoke and mirrors' going here.

Concern is not Cable head-end or distribution network it is poorly shielded customer devices. Interference would affect customers that use RF link to connect set-top box or Cable to TV or other A/V gear.

Those are the same leaky cable modems that interfere with all of my radios.
