Unlicensed “White Space Device” Operations on the TV Band and the Myth of Harmful Interference
نویسندگان
چکیده
The FCC has proposed that the unassigned frequencies between broadcast TV channels – the TV band “white space” – should be opened on an unlicensed basis to certified devices that could offer a range of wireless services to the public. Access to the vacant TV channels in each market has been the subject of intense lobbying, yet far too many of the arguments against white space devices rely upon misinformation about the technologies and the FCC process that will ensure that harmful interference to TV broadcasts and other incumbent services does not occur. We believe that policymakers deserve better than the torrent of misinformation that has characterized the debate over white spaces devices. Therefore, this paper is an effort to help policymakers strike the appropriate balance between protecting existing services from interference while making the extensive benefits of mobile broadband services available and affordable for all consumers.

A Harmful Interference Model for Unlicensed Device Operation in Licensed service Bands
Recent FCC proceedings have considered the notion of unlicensed device operation in licensed bands. Licensed users are concerned about harmful interference while unlicensed device manufacturers are concerned that harmful interference is an imprecise design concept. This paper addresses two elements to these concerns. First, it develops an explicit model of harmful interference to be included in...

The main hurdle in the realization of dynamic spectrum access systems from the physical layer perspective is the reliable sensing of low power licensed users. One such scenario shows up in the unlicensed use of the TV bands where the TV band devices are required to sense extremely low power wireless microphones (WMs). The lack of technical standards among various wireless manufacturers and the ...
