AbstractMultipacket transmission can achieve higher transmission efficiency because many packets are inserted into a frame and per‐packet overhead is small. However, in practice, too many packets cannot be inserted into a frame and too long a frame has higher probability of error. Therefore, the number of packets in a frame must be restricted. This paper analyzes the continuous‐service‐type multipacket transmission with restriction on the number of packets in a frame. Also, the distribution for the number of transmission waiting packets is derived along with the number of packets in buffer,z‐transform of the distribution for the number of packets in a frame, transmission efficiency, average queue length, and average packet delay time. From numerical examples, we examine the influence of the restriction on these performance m
