Cingular Wireless and Lucent Technologies have successfully completed tests on their 3G networks0
Cingular Wireless have successfully completed a call on their test network in Atlanta (built by Lucent Technologies) using High-Speed Downlink Packet Access (HSDPA) technology which is an enhanced version of UMTS/WCDMA 3G. In recent tests it sustained rates of more than 3Mbps and supported a wide variety of high-bandwidth multimedia services including high-quality streaming video, as well as fast downloads of high-resolution images and other large files. Initial HSDPA devices will support 3.6 Mbps peak speeds. As faster devices are released, the network can ultimately deliver theoretical peak data speeds of up to 14.4 Mbps. Cingular has already contracted with Ericsson, Lucent, and Siemens to provide HSDPA network equipment that should be launched in most major markets by the end of 2006.
