摘　　要：为了扩大无线容量,同时支持2.4 GHz和5 GHz频段,双频Wi-Fi设备目前已被广泛地应用在各种场景。5 GHz的使用可以大大减少2.4 GHz频段上的干扰。针对双频Wi-Fi,文中提出一种以提高接入点吞吐率为目的频段选择策略。通过分析可能影响无线接入点饱和吞吐率的相关因素、RSSI、最小竞争窗口以及用户数等,提出一种双频Wi-Fi的频段选择方法。该方法可以有效提高接入点侧的饱和吞吐率,有效提高客户端侧的平均吞吐率。In order to expand the wireless capacity of Dual-Band Wi-Fi devices to support both 2.4 GHz and 5 GHz frequency bands,it has been widely used in various scenarios.The use of 5 GHz can greatly reduce interference on the 2.4 GHz frequency band.Aiming at Dual-Band Wi-Fi,this paper proposes a frequency band selection strategy to improve the throughput of the access point.By analyzing the relevant factors that may affect the saturation throughput of wireless access point,RSSI,minimum contention window,and the number of users,a method of frequency band selection for Dual-Band Wi-Fi is given.This method can effectively increase the saturation throughput rate on the access point side and effectively increase the average throughput rate on the client side.
