Performance evaluation of a fixed relay concept for next generation wireless systems
N. Esseling, Bernhard H. Walke, Ralf Pabst · 2005
This work presents a concept and the related performance evaluation 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. A short introduction is given to the general topic of fixed relaying, the proposed extension to a MAC-frame based access protocol like IEEE 802.11e, 802.15.3, 802.16a and HIPERLAN2 is outlined. A possible deployment scenario is introduced and the simulative traffic performance in a Manhattan-like dense urban environment is presented. 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.
