Another Microsoft white spaces device fails

Another "white spaces" prototype submitted to the FCC by Microsoft stopped working this week, but Microsoft said the device did not interfere with spectrum allocated to television, which was the purpose of the testing. Two months ago, the FCC had to take another Microsoft-backed device out of testing because of power issues. The National Association of Broadcasters, which opposes white space devices, pulled no punches:

"In baseball, it's three strikes and you're out. How many strikes does Microsoft get? If they can't get the device to work in the lab, how are they going to get it to work in the real world?" NAB Executive Vice President Dennis Wharton said in a statement. "Considering where we are in the lab testing process...we think that it's more prudent to continue with the other non-Microsoft devices that are currently going through testing," a Microsoft spokesperson said.
