"White Space" Proponents to Try Again at FCC

Well....we didn't have to wait that long to learn the answer to the question I posed in a previous post concerning the TV "White Space" device testing proceeding, and, I don't think anyone will be very surprised as to what it is.

Microsoft filed a letter with the FCC today claiming that the scanner in one of two WSD prototypes submitted was damaged and "operated at a severely degraded level." The scanner in the wireless device is supposed to sniff for broadcasts in spectrum before transmitting in the band and switch to another band if the first one is occupied. The FCC found that the prototype did not consistently detect TV broadcast signals and could cause interference.

Also, this past Friday, the FCC extended an invitation to interested parties to participate in an on-site visit to the FCC Laboratory in Columbia, Maryland to observe and discuss the test set up and procedures for evaluating the performance of these devices.

The meeting will occur on Thursday August 16, 2007 at 1 PM at the Commission’s Laboratory in Columbia, Maryland. Parties interested in attending should send an e-mail to, identifying the organization and how many individuals plan to attend (space is limited). At the meeting, Commission staff will provide an overview of the tests, answer any questions, and consider suggestions for any further testing to evaluate the performance of TV White Space Devices. Directions to the Laboratory can be found at

Make your reservations early.....
