Break-Even Costs in a Cellular Multihop System with Fixed Relays

Abstract [en]

This paper extends some previous work on the economical feasibility of a cellular multihop system with fixed relays (mesh network) by considering link adaptation. The results are expressed in terms of the break-even cost, which is an upper bound on how expensive a relay can be with respect to a base station. For a system with few hops, the break-even cost is about the same (6-9%) with both fixed and variable link rate. The introduction of a STDMA scheme based on proportional fair scheduling increases the channel reuse factor from 1.5 to 2.5 times per cell in a hybrid with one relay tier. However it does not improve the break-even cost and it introduces bit-rate unfairness in the service delivery.
