Empirical study for IEEE 802.11 and Bluetooth interoperability

The IEEE 802.11 and Bluetooth (BT) wireless networks can provide complementary services and they are likely to be installed within the same environments. Coexistence between the networks will be impaired if the probability of packet collision between the networks is sufficiently large. This paper presents the results of an empirical study focused on evaluating one aspect of the probability of collision: determining the interference power at which packet retransmission is likely to be required. The results from this empirical study are used to substantiate analytical models for interference suppression versus carrier frequency offset. The empirical study and analytical model are used to provide insight into the impact of adjacent channel interference from the interfering wireless service.
