Abstract
It is widely accepted that multi-hop communication will become an integral element in beyond 3G (B3G) broadband networks, because the area that can usually be covered by a single Access Point (AP) is inherently small. This paper elaborates on the potential of a fixed and planned multi-hop architecture for the extension of radio range and for the coverage of otherwise shadowed areas in B3G systems. We particularly focus on a scenario where the range of an AP is extended by four Relay Stations (RSs), each having a receive antenna gain. Based on a set of assumptions on the technologies and paradigms used in such systems we quantify the achievable capacity and illustrate its inter-dependencies with some system parameters such as relaying strategy and RS receive antenna gain. We show how relaying helps to make the very high capacity of a single broadband access point available in a larger area than its original coverage, meeting the expected spatial distribution of the traffic demand more precisely. We propose and compare different mechanisms of relaying in the time domain for a planned infrastructure. Based on these mechanisms we show that the introduction of relay based deployment concepts can substantially increase the capacity of a single AP. We show based on a the assumed Manhattan scenario some promising deployment concepts that allow a spectral efficient wide area broadband coverage in such urban scenarios. Thereby we demonstrate some ideas how to exploit relaying inherent strategies by means of coordination across Base Stations (BSs) to increase the spectral efficiency of the relay based radio network deployment.
