Adjacent channel interference in 802.11a: Modeling and testbed validation

Abstract: -In this work we utilize the model for calculation of the interference power by partially overlapping channels introduced in [1] 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. We validate the results from our theoretical model by applying it on an in-lab testbed, in which we use signal splitters/combiners and fixed attenuators to emulate the wireless channel. Our experiments show that the ne… Show more

“…However, the occurrence of the RSSI decrease in the area Tx(14, 15) and DR(54) does not have any visible effect on T as the RTR was again increased by 2 %. Equal to Angelakis et al [7], the Figures 5 and 6 show the impact on ACI of neighbouring channels. Now Figure 7 depicts the exact same experiment with a channel separation of two non-overlapping 802.11a channels with MN 1 acting on channel 36 and MN 2 on channel 44.…”

“…These issues must be addressed prior to deploying an 802.11a based NANET infrastructure. Angelakis et al [7] qualifies the effect of ACI in terms of throughput within a single node equipped with multiple interfaces. Angelakis et al investigated that neighbouring 802.11a channels have a spectral overlap that produces a significant level of interference which can lead to lossy and unstable links.…”

“…Adjacent channels in IEEE 802.11a, contrary to common belief, can interfere with each other when their connected antennas are close [16], [17], [1]; this occurs when a wireless interface is receiving and another interface in the same mesh node is transmitting. In such cases, the links would need to be assigned channels with a separation that depends on the distance between their corresponding antennas.…”
