If there was any question that LTE is dominating the charge toward 4G, Qualcomm, the primary supporter of competing UWB technology, is now deploying a number of chipsets with LTE support. Verizon is one of Qualcomm's largest customers, and their decision to go LTE has apparently broadened Qualcomm's horizons. The company also says they'll be conducting HSPA+ tests throughout 2008.At the moment, there's three front-runners for the fourth-generation wireless broadband crown: 3GPP LTE (Long Term Evolution), mobile WiMax and 3GPP2 UMB (Ultra Mobile Broadband). All three standards will offer low latency and theoretical max speeds that easily best existing 3G offerings. However, LTE is officially leading the 4G push.

AT&T has said they're planning on migrating toward LTE. Verizon Wireless recently confirmed they would be embracing LTE as well, in order to have a unified standard across both their network and the network of European partner Vodafone. Sprint, of course, is hitching their wagon to Mobile WiMax under the Xohm name.
