WiMAX Question:

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 were slow to mature into economically viable and affordable iterations. The EVDO schema is now in a Revision A version which improves bandwidth considerably. Verizon and Sprint are the first US based carriers to begin wide deployment. Sprint currently has deployed most of its markets with 3G as has Verizon. 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).
