Enhancing location estimation accuracy in WiMAX networks

Mobile location technologies have attracted significant attention as a mean to deal with the ever increasing demand of wireless communication services. With the availability of WiMAX systems, the technology becomes a feasible solution to support location services in wireless broadband networks. In this paper, we utilise some of the WiMAX offered features namely multiple input multiple output (MIMO), adaptive modulation and coding (AMC), beamforming, and relay station (RS) for enhancing the location estimation accuracy in location services. Simulation results show that in term of location estimation accuracy, the proposed solution adheres to Federal Communications Commission (FCC) requirements.
