WRAL-TV has been granted special
temporary authority to test TV white-space technology in areas of North
Carolina. The STA application says WRAL will be working with Carlson Wireless
on the pursuit. Carlson Wireless, based in Arcata, Calif., has several active
white-space projects, including a commercial white-fi network in California’s Sierra
Nevadas and field trials with Google for a medical network in South Africa.
WRAL, the CBS affiliate in Raleigh, N.C., owned by Capitol Broadcasting, was the first station in the country to start broadcasting in high-definition, and was first up with a mobile emergency alert system.
The STA application—callsign

with WRAL and Carlson to provide proper spectrum allocation. Carlson separately
has a similar STA already approved by the Federal Communications Commission.

A more limited white-fi network trial was conducted in Claudville, Va., in
October of 2009.
