Military Voice Services over Wireless ATM Networks: ATM Adaptation Layer Study

Abstract

ATM technology has enjoyed great success, due in great part, for its ability to support a whole range of applications with Quality of Service (QoS) guarantees. Consequently, ATM has become of great interest for the support of services over military telecommunications networks. This report is provided as part of a study on the feasibility of military voice services over wireless ATM networks. In this study we are concerned with the support of low data rate and delay sensitive applications over wireless ATM link, where the ATM Adaptation Layer 2 has been identified as a suitable adaptation layer for the support of such type of traffic. Nevertheless, as currently specified, AAL2 does not provide any protection mechanisms to allow for its efficient implementation over the wireless medium. The work presented in this document includes performance analysis results to evaluate the implementation of Forward Error Correction (FEC) codes, diversity reception mechanisms and/or protocol enhancements to improve the performance of AAL2 over a wireless ATM network.
