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 license exempt 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. License-exempt challenges such as where to place infrastructure equipment and how to minimize interference are also examined.
