Wireless multihop networks overlaid with cellular structure have the potential to support high data rate Internet traffic. In this paper, we consider techniques by which the system capacity of such networks can be increased. First, methods for increasing link capacity in single-user systems are explored. Subsequently, we consider a different set of techniques suitable for multiuser systems. We also investigate the effect of traffic dynamics on system capacity and ways to achieve the maximum throughput. Finally, we present capacity bounds which illustrate how these techniques help in trading off the conserved power for capacity advantage.
