Abstract:

The coexistence between Bluetooth system and IEEE 802.11 frequency hopping spread spectrum(FHSS)equipment is analyzed. Based on the capacity formulae and system simulation, the inter-affection between these networks is compared. A fragment adaptive solution of packet payload length is presented, which can be used to improve the capacity reduction of IEEE 802.11 FHSS network. Analysis results show that the IEEE 802.11 WLAN standard with its inherent mechanism supports this fragment length adaptive algorithm. With the increasing of Bluetooth interfering networks, this adaptive solution can effectively relieve capacity decreasing of IEEE 802.11 FHSS network. The capacity analysis method and adaptive algorithm adopted in this paper can also be generalized into other FHSS networks.
