面向高密度Wi-Fi部署环境下的抗干扰策略
|
摘要
高密度Wi-Fi部署环境如银行、写字楼、mall等,普遍存在的同质干扰问题是制约用户体验及网络质量提升的痛点。首先,针对该问题研究了干扰检测技术并提出一种识别和度量Wi-Fi节点干扰的干扰程度评估模型。随后提出了"容忍+避让"的抗干扰策略,容忍策略基于捕获效应理论及无线资源管理技术,提升了干扰条件下数据通信质量;避让策略采用局部化信道自协调算法和去中心分布式架构,解决同质干扰中的冲突问题。最后,实现了抗干扰机制Wifi AAS。测试结果表明,该机制可提升10%设备性能,且未带来过大开销。
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.
