Why is WiMAX important for mobile broadband wireless?
Mobile broadband wireless or 3G has enjoyed two largely consistent standards, those being the code division multiple access (CDMA) based approach with its evolution data only (EVDO) and the universal mobile telecommunications system (UMTS) and its faster upgrade high speed downlink packet access (HSDPA), which in particular has gained some deployments in the past year. However, these technologies have been slow to mature into economically viable and affordable iterations. The EVDO schema is now in a Revision A version which improves bandwidth considerably. Sprint is the first US based carrier to begin wide deployment. It currently has 10 markets deployed with plans for 21 by the end of 2006. The bandwidth limitations have been significant and the adoption by carriers, particularly those utilizing GSM technology here in the US has been very slow (as they are essentially incompatible technologies). Newer broadband UMTS (universal mobile telecommunications system) systems that are GSM com
