The FCC announced this week the first trial of a database for its white space broadband initiative. White space broadband rules were adopted by the Commission last year in order to provide an opportunity to test whether broadband could be delivered wirelessly in areas of the television broadcast spectrum that are unused. Because those unused frequencies vary in different parts of the U.S., a database of occupied frequencies is required to prevent white space devices from interfering with television broadcasts, cable headends, wireless microphones among other uses of this part of the spectrum.
Spectrum Bridge is the company that has developed the white space database the FCC is testing starting on September 19 and running for 45 days. The FCC and Spectrum Bridge are allowing the public to participate in the trial, via this web site.
Obviously for white space broadband to become a reality, the technology to prevent it from interfering with licensed use of the same portion of spectrum must work flawlessly. If a neighbor's white space broadband access has a deleterious affect on your television signal, then this technology isn't ready to proceed to market.
