I am against this for the sole reason that it interferes!
I remember the article on broadband reports several years ago that showed that tests concluded that cable tv systems were having interference problems with white space devices. Also who knows these devices could interfere with ajacent channel assignments and is no use in markets like LA, Dallas, Philly, NYC, Chicago, San Francisco, Houston, etc. that have a ton of low power channels that are using almost all of the spectrum from 2-51 that is not on ajacent channels from neighboring markets. Also how would this survive the planned reduction of OTA TV allotments from 2-51 to 2-31 I think white space is dead there as we will have channels fighting for 2-31 yet alone have any open space for white space channel devices we would be better served if the FCC auctioned a block of spectrum to companies that would use it as a WISP than to give it to white space.
