Request reopens matter laid to rest just six years ago.
The FCC has reopened the difficult question of technical standards for radio receivers.
Everyone agrees that poor receivers impair efficient use of spectrum. In particular, receivers that respond to a wider swath of frequencies than necessary can receive interference from unwanted signals close by the intended signal. Just ask LightSquared, whose plans to use mobile satellite frequencies on terrestrial towers failed because its signal was close enough to GPS frequencies to overpower some GPS receivers.
Less selective, more interference-prone receivers are cheaper to manufacture. Market forces are not much help because a more selective (and hence more expensive) receiver is rarely of immediate benefit to the purchaser. The improved receiver does benefit other users seeking to operate on frequencies nearby, as better GPS receivers would have benefited LightSquared. But the manufacturer gains no competitive advantage to offset the higher price. So manufacturers, especially of consumer equipment, tend to supply the least selective (and least expensive) receivers that will work in the current spectrum environment.
A situation like this, where market forces act against the public good, is a classic set-up for regulation.
The FCC tried. Just over ten years ago it issued a Notice of Inquiry on whether to include “receiver interference immunity performance specifications” in its rules. After sifting through sixty-odd comments, and then waiting a few years, the FCC terminated the proceeding in a terse one-pager.
Now the issue is back.Continue Reading...
