Abstract

The WLAN(IEEE 802.l1b) and Bluetooth(IEEE 802.15.1) employed on 2.4㎓ ISM band wireless networks provide complementary services within the same environments. Coexistence between the networks will be impaired, if the mutual packets are uncertainty associated the timing or gaussian distance. This paper analyzes the impact of the mutual interference on the services performance in order to develope a method of coexistence between the WLAN and Bluetooth. The analysis is illustrated by examining the symbol error rate versus signal to noise interference ratio in terms of the carrier frequency of set.
