CATMES - Cellular ATM Evaluation System
نویسندگان
چکیده
During the recent years more and more attention has been focused on the usage of Asynchronous Transfer Mode (ATM) in the wireless environment. Third generation mobile network standards like UMTS and IMT-2000 have chosen ATM as a transport technology candidate for terrestial circuits in cellular networks. Why ATM? A prototype system called CATMES, Cellular ATM Evaluation System, was created to investigate this question. As a background the current transport problems are shown. CATMES system is described in detail, and the major system impacts are shown. The new ATM Adaptation Layer type 2 (AAL2) is explained and compared to other alternatives. Finally some interesting results concerning transmission efficiency, AAL2 details and synchronisation aspects are evaluated.
