The System Throughput Estimation Method for Multi-cell WLANs

摘要

摘要: 在多小区无线局域网(WirelessLocal AreaNetworks,WLAN)中,由于存在小区间接入访问点同频干扰,以及小区间同频用户干扰,其系统性能与单小区网络具有很大不同.本文提出了支持多种用户传输速率共存、支持用户非均匀分布的多小区WLAN系统吞吐率估计算法.通过对多小区WLAN中接入访问点的布置、信道的配置进行仿真,结果表明即使在存在小区间同频干扰的情况下,估计算法也能得到满意的吞吐率估计结果.

Abstract: In multi-cell Wireless Local Area Networks （WLAN）, co-channel interference between access points, and interference between co-channel users located in neighbored cells are existed, which lead the system performance different from the situation in a single-cell WLAN. A system throughput estimation method is proposed. Three important features of this method are that co-channel overlapping is allowed, hybrid data rates are allowed, and non-uniform distribution of users is allowed. The simulation results on the access point placement and the channel assignment show that the estimation method meets system design.
