Abstract
IEEE 802.22 Wireless Regional Area Network (IEEE 802.22 WRAN) is considered for operating in the television (TV) bands without causing harmful interference to the primary users i.e. TV users. To tackle this problem, the authors propose an alternative method for calculating the protection distances between the WRAN devices and the TV protection contour where the WRAN devices are not permitted to radiate their powers since they may cause harmful interference to the TV users. The proposed calculation is similar to the one used for the impact study of ultra wideband (UWB) devices to the existing services in Japan. In this approach, the protection distances are calculated based on the interference-to-noise ratio (INR) at the TV receiver with respect to two deterministic propagation models. One is free space model and the other is spherical earth model. In addition, the comparison of the propagation loss and the protection distances between the proposed study and the conventional one are also presented.
