Abstract

The signal interference problem in this high-density deployment of Wi-Fi like banks, offices, mall, it is the pain point restricts user experience and network quality. Firstly, this paper studied the interference detection technology, and proposed an interference level evaluation model to recognize and measure the interference of Wi-Fi nodes. Then, it put forward the strategy of tolerance & avoidance and the tolerance policy based on the capture effect theory and wireless resource management technology. It improved the quality of data communication under interference condition. The collision avoidance strategy adopted the local channel self-coordination algorithm and the decentralized distributed architecture to solve the conflict problem in the homogeneous interference. Finally, it implemented the mechanism WifiAAS. Test results show that it can improve the performance of 10% and not too expenses.
