Performance and coexistence analysis of multiple IEEE 802 WPAN/WLAN/WRAN systems operating in TV White Space

This paper presents the performance and coexistence analysis of multiple IEEE 802 wireless communication systems operating in TV White Space (TVWS). Three IEEE 802 groups with systems operating in TVWS, namely IEEE 802.15.4m Low-Rate Wireless Personal Area Network (LR-WPAN), IEEE 802.11af Wireless Local Area Network (WLAN) and IEEE 802.22 Wireless Regional Area Network (WRAN) are investigated. First, system performance and achievable operating range for these systems in the absence of interference are evaluated, in accordance to design parameters suited to targeted application scenarios respectively. Then, assuming operation in close proximity, the three systems in the presence of interference are investigated to assess their error performance and critical distances to interfering device. The results highlighted several insightful critical parameter settings such as interferer-to-victim separation and interferer transmit power, beyond or below which, cause intolerable degradation to victim systems as quantified by the minimum required error rate performance.
