Microsoft Fails Again With White Space Tech Device

A device submitted by Microsoft for US Federal Communications Commission (FCC) testing of wireless 'white spaces' technology has stopped working and been taken out of the process.

The wireless prototype, which was not made by Microsoft, unexpectedly stopped working on Wednesday, Microsoft said on Friday. In February, the FCC took another Microsoft-submitted device out of testing because it had power problems.

Microsoft said the problems that took the two devices out of testing were unrelated to interference and that the units were experimental, not production devices.
