It has been reported that the capture effect can improve the performance of slotted ALOHA systems. Further improvement can be expected when the number of base stations is increased. The performance of such slotted ALOHA systems with multiple base stations is analyzed with the aid of the equilibrium point analysis. Not only the capture effect but also the packet dropping due to the finite number of retransmission trials are taken into account. The numerical results indicate that the finite number of retransmission trials mainly contributes to the improvement of the packet dropping probability in the range of the light input traffic, while the number of base stations mainly contributes to the improvement of the overall throughput and the average transmission delay in the range of the heavy input traffic.>
