North Carolina city ventures into spectrum white spaces

Print More

Wilmington, N.C., was the first community in America to discontinue analog broadcasting. Now it’s the first to test a municipal WiFi network using white spaces between DTV channels, reports Broadcasting & Cable. So far the city has been using white-space wireless cameras for traffic and surveillance in a park and highway; soon cameras will also check water levels. And there’ll be public WiFi in a park and school. The city is being assisted by Spectrum Bridge, a real-time online marketplace for radio spectrum. That firm is supplying a spectrum database to prevent interference with local TV stations.
