Wireless Baseband Evolution - Multiple Design Approaches for 4G Modems
The evolution of 4G wireless baseband indicates there are two evolving technologies that are currently competing for the leading position; namely LTE and WiMAX. WiMAX has emerged as the technology of choice for computing devices and M2M, as well as for fixed wireless connections in underdeveloped areas. It is promoted by the WiMAX forum, led by Intel and other companies. LTE is evolving as the "GSM" direction towards cellular broadband and is promoted by the 3rd Generation Partnership Project (3GPP) and adopted by baseband OEMs and operators including Qualcomm, ST-Ericsson, Verizon, Vodafone and others.
