WiMAX has a relatively long history of development, and it was long considered the basis of next generation 4G networks. However, deployment lagged, and uptake was relatively slow for a variety of reasons, including immaturity of the wireless broadband market itself, slow deployment of 4G networks, spectrum issues, and the like. Within the past several years it has gained some momentum, and there have been significant deployments. However, its future is now clouded by the growing popularity of the competing technology, LTE.
