Abstract :
This paper is focused on the relation between the CLR (cell loss ratio) and blocking probability, GoS (grade of services) parameters in the wireless ATM (asynchronous transfer mode) access network which consists of access node and wireless channel. The traffic model of the wireless ATM access network is based on the cell scale, burst scale and call connection level. The CLR equation due to buffer overflow for wireless access node is derived for CBR (constant bit rate) traffic. The CLR equation due to random bit errors and burst errors for wireless channel is derived. Using the CLR equation for both access node and wireless channel, the CLR equation of the wireless ATM access network is derived. The relation between the CLR and blocking probability is analyzed for CBR traffic to evaluate the CLR performance of a wireless ATM access network
