Abstract
This paper presents the design and performance insights of a multiradio multihop network using IEEE802.11n radios. The widely adopted architecture that uses 2.4GHz access and 5.8GHz multihop backhaul links is considered. More specifically, this study looks into the feasibility of such design to provide backhauling between two base stations while providing WiFi access along the multihop routers. The analysis covers the performance of different designs or configurations such as distance between hops, multihop chain distance, choice of Modulation and Coding scheme (MCS), backhaul link rate, channel bandwidth, number of spatial streams required to support certain capacity per AP and connection rate per user. The findings show that by ignoring the number of hops required, at least 3 MIMO spatial streams and 16QAM3/4 are required to support the basic 2Mbps connection rate per user per AP along the multihop chain. This is on top of 120Mbps raw physical data rate required to provide backhaul connectivity between the base stations.
