Relays-Enhanced LTE-Advanced Networks Performance Studies

This paper proposes a study on the performance of multi-hop relays networks. The authors demonstrate the importance of the relays for coverage and capacity enhancement and study how the number of relays and their position inside the cell impact the performance, and how an efficient relay location scheme can guarantee better performance with less relays per cell. Further they give an estimation of the amount of power per square meter on the ground when relays are used, with respect to traditional network, showing the fundamental role of relays for green networking.
