Existing and potential wireless Internet service providers (WISPs) and vertical markets such as government and education are considering the benefits associated with Worldwide Interoperability for Microwave Access (WiMAX), specifically the flexibility and cost reduction benefits associated with the license-exempt portion of WiMAX. However, the popularity of WiMAX is causing concern among some operators who fear that standardizing the licenseexempt broadband wireless spectrum may lead to overcrowding, while other operators hope to establish new solutions that can accommodate the sharing of spectrum and infrastructure locations

This paper provides WISPs and vertical markets with technical information related to deployment of a license-exempt WiMAX solution. It compares license-exempt and licensed WiMAX solutions and highlights benefits such as cost-effectiveness and deployment flexibility. License-exempt challenges such as where to place infrastructure equipment and how to minimize interference are also examined.
