Abstract :
The throughput and response time calculations of a multisite mobile digital radio system were presented previously by the author (see IEEE Trans. Veh. Technol., vol.39, no.8, p.190, 1990, and IEEE Trans. Veh. Technol., vol.40, pt.2, no.2, p.161, 1991). In those papers, two simplifying assumptions are made without providing detailed analysis. These two assumptions are: (1) the probability of a message getting through the uplink radio channel is calculated using the nearest three sites only, and (2) the probability of FM capture is calculated using the two strongest signals only. The validity of these two assumptions is examined. Results indicate that these two assumptions are good in general. The intrinsic instability associated with a contention channel is not addressed
