IEEE 1900.7 standard for white space dynamic spectrum access radio systems.

Various measurements and studies have shown that some licensed frequency bands are underutilized at certain times and in certain locations. In particular, TV bands have been shown to have unused spectrum. Such observations have triggered strong interest in white space dynamic spectrum access among researchers, wireless equipment manufacturers, and standards development organizations. The IEEE Standards Committee on Dynamic Spectrum Access Networks has created the White Space Radio Working Group in June 2011 to develop the IEEE 1900.7 standard for white space dynamic spectrum access radio systems. The draft of this standard is now finalized and ready for review by a broad audience during the sponsor ballot procedure. This paper gives an overview of key concepts and technologies of the draft standard P1900.7, including its use cases and requirements, its physical layer and MAC sub-layer.
