Coverage, capacity and energy efficiency of TV white space technology
Coverage, capacity and energy efficiency of TV white space technology
The increasing demand of wireless telecommunication services is stressing the availability of radio spectrum to accommodate new services. Nevertheless, spectrum usage surveys performed in different regions reveal an under-utilization of radio spectrum. TV White Space (TVWS) technologies allow a dynamic usage of the Very High Frequency (VHF) and Ultra High Frequency (UHF) television channels. In this paper, we investigate the coverage range, capacity, and energy efficiency of IEEE 802.22(b) technology. We consider Ghent, Belgium, to evaluate a realistic scenario. The higher coverage range is 7.9 km for IEEE 802.22b, when using Modulation and Coding Scheme (MCS) 1/2 QPSK. The best trade-off between coverage and capacity in Ghent suburban scenario is achieved for the MCS 2/3 16 QAM, with an energy efficiency of 50 square km.Mbps/W, a Base Station (BS) maximum delivered bitrate of 16.064 Mbps and a coverage range of 2.9 km. To ensure a percentage of users covered higher than 97% are required 20 BS.
