The coexistence problem between Bluetooth network and IEEE80211FHSS network using FH scheme in wireless personal area network (WLAN) is studied, and their mutual influences are compared through capacity analysis and system simulation.On the basis of this, The proposed method is based on packet length adaptation to improve the anti-jamming performance of IEEE802.11FHSS networks. The proposed scheme is analyzed and simulated. The results show that the inherent mechanism of IEEE80211WLAN standard can support the proposed scheme Method, and improves the robustness of the anti-interference. With the increase of the number of Bluetooth interference networks, the anti-interference performance of the IEEE802.11FHSS network adopting the adaptive scheme is obviously enhanced and the decrease of the network capacity is effectively alleviated. Capability analysis and package load length segmentation adaptive schemes can also be extended to other FHSS networks.
