Abstract

Abstract:

It is reported the discovery of indoor spatial spectral holes in television white space based on the real measurement in the urban area of Beijing China. The report shows more than 18% urban indoor area of Beijing has spatial frequency holes, and proves that the observed spatial spectral holes can be used by cognitive radio users forming a low power short distance small cell without causing interference to nearby television receivers. The research on spatial spectral hole provides extensive spectrum access opportunities for employing emerging dynamic spectrum access technology to meet the massive demands for future wireless services.

Key words: cognitive radio networks, spectrum occupancy measurement, dynamic spectrum access
