Different from the earlier studies, in addition to both 802.11af access point and clients listening to the busy tone, they also adjust their communication power according to the location information and use hopping for communication, if needed Acccordingly, interference caused to 802.22 systems has been reduced while the 802.11af systems are still able to communicate. This study quantifies the 802.11af and 802.22 system performances in terms of interfering packet rate and succesful packet transmission rate for different scenarios considering the communication parameters and channel models adapted for the standards.trinfo:eu-repo/semantics/closedAccessTV white spaceCoexistenceIEEE 802.22IEEE 802.11afBusy tone,Power controlConference ObjectWOS:000413813100532N/AN/A
