Ensuring coverage quality with tolerable interference through optimizing the deployment of BSs in radio frequency communications

Blocking probability, coverage quality, and interference are three imperative factors to be included in planning a radio frequency (RF) communication system. Coverage quality refers to the acceptable communication quality, which can be determined in three ways: land surface, population, or traffic. In a RF communication, interference can be categorized into noise, co-channel interference, and adjacent channel interference. When a wireless network becomes congested, either extra channels or extra Base Stations (BSs) can be introduced. As the blocking probability is strongly depended upon the coverage quality and interference, we focus on the study of the impact from both factors. Since assessing these interrelated factors is complicated when planning a system with thousands of access points, we present a mechanism with a set of optimal parameters that maximizes the communication capacity and meets the actual coverage quality with tolerable interference in building an RF system. In this paper, a sample data of wireless usage from central Taiwan is taken to evaluate the feasibility of the propose method. Solutions of co-channel interference are also presented to limit the interference in both up-link and down-link channels.
