With the final transition of television from analog to digital soon upon us, the FCC has scheduled for consideration at its November meeting two items that will address the use of the television spectrum after the transition – one designed to improve television reception, and the other viewed by television broadcasters as a threat to that reception.  The potential positive development is Distributed Transmission Service ("DTS").  The other proposal – which is far more controversial – is the proposal to authorize "white spaces devices" that operate wireless devices within the portion of the spectrum that will still be used by television stations after the transition.

DTS is the proposal that would allow television stations to use more than one transmitter to reach its service area.  Like the use of FM on-channel boosters, a DTS system would permit stations to use multiple transmitters located throughout their service area, each broadcasting on the same channel, but operating at a lower power than the traditional television station which usually operates from a single high-powered transmitter.  The idea is that, in digital, signals distributed from lower power transmitters spread throughout the service area might be less susceptible to signal impediments from terrain and building obstacles than would a single high-power transmitter.  The FCC proposed adoption of this system several years ago with little opposition, but it has languished.  Some have suggested that the experience in Wilmington, where some people who lived far from the center of the market were having over-the-air reception problems, gave new impetus to DTS as one way to provide better service to these more remote areas.…
