	abstract = {In this paper we present results on the system level performance of the IEEE 802.22 standard with sensing functionality, using a highly detailed implementation of the IEEE 802.22 protocol stack in the NS-2 simulator. Our attention is focused on the effect of spatio-temporal wireless microphone (WM) activity on the performance of the IEEE 802.22 network with spectrum sensing considered. In general we find that the frequency of WM appearance and activity duration should be quite high in all channels not used by the TV broadcaster to reduce IEEE 802.22 throughput, for example about 50\% WM occupancy in each of totally four channels. Furthermore, we find that two-stage spectrum sensing is the best sensing strategy compared to the single-stage and consecutive sensing strategies for reduced interference to WMs and the one that achieves lowest packet loss in the IEEE 802.22 system. Finally, when increasing distance between the IEEE 802.22 node and the WM such that received signal from the WM falls below detection threshold, we find that IEEE 802.22 throughput reduces due to false alarms in the coarse sensing stage while impact on the WM is acceptable.},
