Abstract :
This paper analyzes dynamic channel assignment in cellular systems where the base stations are placed at random. Using a simple dynamic channel assignment algorithm, random systems are compared to an ideal hexagonal system. Under log-normal shadow fading the random system has capacity within 1 dB of the hexagonal system. This paper looks at both the uplink and downlink and finds that performance is similar to previous downlink analysis. Thus, at a modest cost in performance, deployment effort is greatly reduced
