Abstract: An analytical method for investigating slotted ALOHA land-mobile networks is present-ed. The probability of successful reception and throughput is assessed for a single base station, taking account of contending transmissions and receiver noise. Receiver capture is assumed to occur if the received signal power exceeds the joint interference power by a certain margin, called the receiver threshold. Rayleigh fading and UHF groundwave propagation are considered. Results are extended for a cellular network considering the interference from packet transmissions in other (co-channel) cells. It is seen that in packet-switched cellular nets, frequency re-use distances may be substantially smaller than in circuit-, |
