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 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 one or more Relay Stations (RS), 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 throughput in the area covered by a RS and illustrate its inter-dependencies with some system parameters such as AP transmit power, pathloss coefficient, relaying strategy % , distance between AP and RS and RS receive antenna gain. We show that substantial increases in peak throughput can be achieved through multi-hop relaying. This helps to make the very high capacity of a 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.
