Extended partially overlapped channel interference model and study for 802.11 Wi-Fi communications

In this paper the authors extend the tests and model verification related to the partially overlapped channel interference in Wi-Fi communications. Recently more and more papers have investigated the side effects of the channel interference on the throughput parameter. The paper proposes a theoretical model and an experimental approach to obtain useful information regarding channel allocation and spatial reuse in conditions of the intense traffic, by exploiting the data related to the site interference. The paper results determined how smart planning of the operating channel versus the observed interference spectrum configuration can reduce the amount of interference impact and eventually improve Wi-Fi network performance and it also confirmed an alternative way to avoid interferences, without changing the channels configuration (desired or jamming), which consists on getting out of the jamming signal´s interference range, after estimating this range.
