Abstract :
A simulcast network employs a time-slotted relay discipline; radios re-transmit the message received in the previous slot. Design considerations include the number of retransmissions needed to achieve the desired level of connectivity, and techniques for mitigating the interference caused by simultaneous transmissions. The network connectivity is determined by means of a Monte-Carlo simulation that includes a propagation model and a receiver error rate model. It is shown that a simulcast network can provide a much higher connectivity than one in which only one radio transmits at a time
