Planning of WiMAX OFDMA frame parameters in real world deployments

The WiMAX system, based on the IEEE 802.16 standard offers a large degree of flexibility to allow optimal deployment in different scenarios. For that purpose it provides a large set of parameters to be configured and tuned. The paper introduces the main configuration parameters, to be planned ahead for a successful deployment of a mobile WiMAX system, and proposes a methodology to determine those parameters. The proposed methodology is an iterative process aimed at real world deployments where site layout is asymmetric and far from ideal hexagonal layout, traffic density and propagation conditions are not uniform and the nai¿ve approach of regular re-use factor based planning is not adequate.
