Cost Analysis of Wireless Multihop Architectures
2004 (English)Conference paper (Refereed)
Previous studies have shown that multihop techniques can improve the capacity/coverage of a hybrid cellular system, but the economic gain is still an open question. An infrastructure cost analysis is performed in this paper on two hybrid cellular architectures: one using terminals as relays and one using fixed relays.
For the first architecture we show numerical examples in which the infrastructure cost is 20% to 40% higher when multihopping is not used. The size of the gain depends on the density of relaying terminals. For the second architecture the cost ratio between deploying a new macro base station and deploying a wireless relay. In the selected examples, the infrastructure cost is 25% to 100% higher when multihopp is not used, for a cost ratio between a macro base station and a relay varying from 20 to 34.
