Abstract

Partially overlapped channels were demonstrated to have the potential of improving the network performance. One example is an increased capacity in a well saturated network. We address the problem of Wi-Fi network planning incorporating partially overlapped channels by more efficiently exploring the spatial reuse to increase the network capacity. We exploit that the interference ranges for separated channels are different, which can be utilized to deploy access points non-uniformly. In this paper, we formulate the problem, show that it can not be solved in polynomial time. Therefore, we propose a greedy optimization algorithm and validate the theoretical results through computer-based simulations.
