Delay and Throughput Analysis of a Fixed Relay Concept for Next Generation Wireless Systems

This paper presents a concept and performance analysis for a wireless broadband system based on fixed relay stations acting as wireless bridges. The system is intended for dense populated areas as an overlay to cellular radio systems. The proposed extension to a MAC-frame based access protocol like IEEE802.11e, 802.15.3, 802.16a and HIPERLAN2 is outlined. A possible deployment scenario is introduced and, following up on a previous paper about the simulative evaluation, this paper presents the analysis to estimate the traffic performance of the realying solution. It is established that the fixed relaying concept is well suited to substantially contribute to provide high capacity cellular broadband radio coverage in future (NG) cellular wireless broadband systems.
