This paper discusses two of the advanced techniques, fractional frequency reuse (FFR) and multi-hop relay (MR), available to the WiMAX network operator for improving the quality of service (QoS) for the cell edge user. The benefits of FFR are shown as reductions of the interference levels, while the benefits of MR are shown as improvements in coverage and signal quality. The corresponding results have been obtained through analytical studies and network planning exercises and are supported by system level simulations.
