Extended Abstract: Understanding the Effect of Access Point Density on Wireless LAN Performance
Overview This paper presents a systematic experimental study of the effect of inter-cell interference on IEEE 802.11 performance. With increasing penetration of WiFi into residential areas and usage in ad hoc conference settings, chaotic un-planned deployments are becoming the norm rather than an exception. These networks often operate many nearby access points and stations on the same channel, either due to lack of coordination or insufficient available channels. Thus, inter-cell interference is common but not well-understood. According to conventional wisdom, the efficiency of an 802.11 network is determined by the number of active clients. Surprisingly, the paper finds that with a typical TCP-dominant work-load, cumulative system throughput is characterized by the number of interfering access points rather than the number of clients.
