Today on a Motorola trunked SMR, there exists a limitation on the amount of ISW traffic a SMR fixed end site can receive. This limitation is due to collisions between ISW's (Inbound Service Words). The ISW protocol utilizes the Slotted Aloha model. Although this model greatly reduces the probabil- ity of ISW collision, it cannot eliminate collision. Therefore, iftwo or more mobiles transmit simul- taneously, a high collision probability exists.
