Adjacent and co-channel interference is one of the biggest problems in the IEEE 802.11 standard. It is believed that the issue mainly concerns the 2.4 GHz band due to insufficient number of non-overlapping channels. Co-channel interference occurs in both bands, however, and it is associated with the channel assignment method. The authors analyzed the level of interference in both bands for two AP distributions on the X-Y plane. The first distribution was symmetric, while the second one was a part of an actual multi-flat building. The Minimum-Spanning-Tree-Inspired (MISTI) algorithm, previously developed, was used for the channel assignment.
