Military Voice Services over Wireless ATM Networks: Performance Analysis of FEC Schemes at ATM Transport Over Wireless Links

Abstract

Wireless ATM was designed to extend the support of broadband, multimedia services provided in fixed ATM networks to the wireless/mobile environment in a seamless and efficient manner. It is a candidate wireless networking technology for future tactical military networks which have adopted ATM in the core network. The bandwidth-limited, error-prone nature of wireless links poses significant challenges in the design of wireless ATM. This report is part of a study on the feasibility of military voice services over wireless ATM networks and is concerned with the impact of wireless link errors on the performance of ATM. The work presents a review of various error control schemes proposed for the efficient transport of ATM over point-to-point wireless links. Due to the strict latency requirements of voice applications, only error control schemes based on Forward Error Correction are considered. The performance of these schemes is analyzed for the random-error channel and for the Gilbert-Elliott burst-error channel.
