Has anyone been following the 'White Space' debates?

I'm not sure what kinds of 'devices' will be transmitting but presume they will be related to data networks and video receivers.

So, where geographically can these devices operate without causing additional interference problems? Judging from the current difficulties related to spectrum management during the DTV transition, population centers are just not suitable.

Are the TV channel allocations going to be 'cast in stone' after Feb of 2009? Will concern about interfering with the devices hamper the allocation of channels to upstart TV stations wishing to operate where white space exists?

Will these be Part 15 devices. If so, the proposed built-in scanning must be effective because consumer users, who know nothing about radio interference, will assume the devices are appliances.

Certainly, in today's technological enviornment, spectrum cannot be wasted through under-utilization.

Nick,

I think that placing choke on the antenna would defeat the purpose of an antenna.

Being curious, I searched for Tower Guy's cardiac monitor incident. It happened during the late 90's just as he reported. Consequently, the FCC created a new radio service for medical telemetry systems. But, I wouldn't be surprise if 'legacy' systems still operate in the TV band.
