Abstract :
This paper analyzes cellular systems where the base stations are placed at random. Analysis compares the base station to mobile link in random systems to ideal hexagonal systems. Under log-normal shadow fading and sectorizing-but no channel planning-the random system has carrier to interference levels within 4 dB and spectral efficiency within 2 dB of the hexagonal system. A simple linear-time channel assignment algorithm reduces each of these differences by 1 dB. Thus, at a modest cost in performance, deployment costs and deployment speed can be greatly reduced
