  1. T. Smura, Competitive potential of WiMAX in the broadband access market: a techno-economic analysis, in Proceedings of ITS 2005, 2005 (pdf)(bib)
    Abstract: WiMAX radio networks have been proposed as an alternative technology to provide services for the fixed broadband access market, currently dominated by DSL and cable modem systems. In this paper, the economic feasibility of WiMAX network deployments is analyzed with a quantitative techno-economic model. The model is used to assess the coverage, capacity, and cost characteristics of WiMAX systems in contrast to the forecasted evolution of the highly competitive marketplace experiencing increasing data rates and decreasing tariffs. The results of the analysis show that WiMAX network deployments can be profitable in dense urban areas as well as in rural areas where the availability of other alternatives is limited. Low profitability can be expected in urban and suburban areas with medium population densities and good availability of other access network alternatives. The most critical success factors regarding the profitability of WiMAX network deployments are the CPE price and broadband tariff levels. The performance of the systems appears to be suitable for the broadband traffic demands of today, but the emergence of services requiring higher data rates may turn out to be problematic for WiMAX operators.
