Qualcomm starts testing its 4G in spring

At the Telecom World 2006 event Qualcomm presented its 4G technology. Qualcomm said that CDMA2000 1xEV-DO Revision C will be released in the second quarter of 2007 and become commercially available in early 2009. In spring 2007 Qualcomm will start testing its new UMB 4G technology that is said would offer mobile data speeds up to 280Mbps, using MIMO technology and scalable bandwidths up to 20 MHz. UMB is based on the Flash OFDM technology that Qualcomm picked up when it acquired Flarion Technologies. According to Qualcomm UMB will eventually compete with the turbo 3G, LTE (Long Term Evolution), which targets 4G downlinks of 100Mbps and uplinks of 50Mpbs using OFDMA modulation.
