A comparison of radio resource management strategies in bunched systems for indoor communication

We investigate the performance of different channel selection strategies in a 3-dimensional indoor environment. The selection strategies are part of a locally centralized or bunched radio communication system using the SIR as a basis for the channel selection decisions. We evaluate the capacity and the complexity of the system for the different strategies. In the performance evaluation, fixed channel assignment (FCA) is used as a reference. The result show that the capacity is more than five times higher in the bunched system compared with the FCA system for the LNF (lowest number first) strategy. We also investigate the impact power control has on the system performance.
