Effective Channel Planning of IEEE 802.11 Networks as a Plane Tessellation Problem. Part 3. Solutions of Best Channel Configuration Selection Problem for Eight-Channel Case

Abstract

When solving the problem of channel planning of IEEE 802.11 wireless access networks, it is necessary to allocate channels for access points so that the selected channel configuration provides minimum negative mutual influence. We will consider the covering of the plane “tessellation”, i.e. the densest filling, by coverage areas of access points groups, which in the spectral sense correspond to channel clusters. By assigning a channel to each of the access points, we obtain a set of possible configurations, each of which corresponds to a possible solution of the channel planning problem. When solving actual design problems in the 5 GHz band, it is often necessary to take into account channel plans that include 8 or more channels. Based on the previously proposed model and method, in this paper, solutions to the problem of finding the best channel configuration for clusters consisting of 8 access points are obtained, and their characteristics are shown in relation to their geometry.
