Adjacent Channel Interference in 802.11a: Modeling and Testbed Validation

In this paper, the authors utilize the model for calculation of the interference power by partially overlapping channels introduced in and combine it with the Signal to Interference plus Noise (SINR) criterion for signal capture to quantify the effect of Adjacent Channel Interference (ACI) in 802.11a. They validate the results from their theoretical model by applying it on an in-lab testbed, in which they use signal splitters/combiners and fixed attenuators to emulate the wireless channel. Their experiments show that the neighboring channel interference affects the 802.11a with two mechanisms: the packet capture at the receiver and the Clear Channel Assessment (CCA) mechanism.
