Wireless Access Via "TV Whitespace" Coming Soon?

Progress is an interesting thing. You may recall that television took a step forward in early to mid 2009, as decades old broadcast signals were once and for all retired when the industry switched from analog to digital. By doing so, a wide array of frequencies were released to the open air for other use. Speculation as to what would become of the spectrum of frequencies that once held our favorite TV channels has been standard technology news. As of late, the potential has been realized, and testing has begun on "TV white space" wireless data networks in parts of the country.

Since the switch there have been a few stories buzzing around related to the up for grabs upper 700Mhz spectrum known as "TV white space." In 2008, The FCC agreed to make the space available for unlicensed use after coming to a unanimous decision on its future application. Such a move prompted Google, Microsoft, HP and other big players to query its technical appeal for Internet access.

In recent news, it has been reported that in the city of Wilmington, and in the county of New Hanover, N.C., wireless services based on the spectrum are now being tested in what is being dubbed as a "smart city" deployment. Spectrum Bridge, Inc., a wireless communications solutions provider whose website announces "the world's first TV white spaces network" (in Claudville, VA) has been involved with the project with TV Band Services LLC. A summary of project details are outlined in Spectrum Bridge Inc.'s official press release which may be found at their web site. The current Implementation of the project describes devices such as Department of Transportation (DOT) traffic cameras real time traffic data for safety and law enforcement purposes. Other uses include public WiFi access in community parks, and environmental monitoring controls which are usually accessed and managed by vehicle and foot.

One of the major concerns with using the white space for communications has been the potential for interference and signal strength in various areas. As the technology is now in its early implementation and infancy stage, it will be interesting to see how it matures over time. Compared to current wireless access technologies, a competitive price-point could be very appealing, making it a welcome guest in any community.
