Nortel Completes First Mobile HSUPA UMTS Call
Yesterday Nortel announced that it had completed the first bi-directional high-speed connection between two mobile devices. The technology, called HSUPA, is the next evolution of the HSDPA networks that are currently being rolled out in the United States and other countries.
The advantage of HSUPA (High Speed Uplink Packet Access) is that it allows for high bandwidth uploading of data as well as the high-speed downloading that comes with HSDPA (High Speed Downlink Packet Access). This opens the door for better quality VOIP (Voice Over IP) and video calling, two applications that rely as heavily on the uplink speed of a connection as much as they do the downlink speed, as well as wireless file transfers.
Nortel’s mobile to mobile HSUPA test managed to reach upload speeds of 1.4Mbps, or about 4 times the speed obtainable with current UMTS and HSDPA network connections.
