The increase of ZigBee popularity and usage in different home area networks exert a new challenge for operating ZigBee in an environment that is already using Wi-Fi. Sharing the spectrum between these two wireless technologies affect the functionality of ZigBee as it may cause a high packet error rate and major drop in the throughput. In this paper, the authors studied the effect of Wi-Fi interference on ZigBee channels by using the cognitive radio as spectrum analyzer and computed the Packet Error Rate (PER) of each of the ZigBee channels. The results that they have obtained contradict the previous analytical and simulation results in which the effect of Wi-Fi on ZigBee has been studied.
