Abstract

In this Chapter, we envision wireless multi-hopping as a complementary technology to conventional cellular networks. Hybrid wireless networks consisting of mobile base stations are expected to play a vital role in enhancing future cellular communications. However, numerous challenges pertaining to the wireless network and the user equipment are yet to be addressed. We herein utilize multi-hop relaying as an overlay architecture for single-hop TDD W-CDMA cellular networks. In our proposed architecture, namely Ad hoc-Cellular (A-Cell) relay, the inherently high node density in cellular networks is used to reduce power consumption, and enhance coverage and throughput. A-Cell increases spatial reuse via directive antennas and GPS. We derive an analytical model for A-Cell based on multi-dimensional Markov chains. The model is then used to formulate A-Cell call blocking. To the author's best knowledge, this is the first time that directive antennas are used as a means to reduce interference, conserve energy and enhance spatial reuse in a multi-hop UMTS wireless network.
