Nortel Demos HSUPA Calls

Nortel has successfully achieved the industry's first simultaneous uplink and downlink high-speed wireless calls between two mobile devices at uplink speeds four times faster than current UMTS services. Nortel's demonstration used it's commercial UMTS Base Transceiver Station and Aeroflex's TM500 handset simulator to exchange VOIP, videos and files at uplink speeds of 1.4 Mbps.

Nortel's HSDPA technology is already being rolled out by operators to improve the downlink capacity of commercial 3G networks. Nortel's HSUPA is expected to be available from the beginning of 2007 and to deliver a higher uplink throughput, reduced latency, and higher capacity, with a software upgrade of commercial networks.

"The successful demonstration of simultaneous HSUPA and HSDPA across our commercially available equipment highlights Nortel's continuous drive for technological innovation within wireless broadband markets," said Jean-Luc Jezouin, vice president GSM&UMTS Products, Nortel. "Nortel is committed to providing today's wireless operators with simple, cost-effective solutions that improve the quality and range of services to subscribers to maximize opportunities for increased revenues."

Nortel achieved the industry's first HSDPA mobile call in January 2005. Nortel and LGE completed the first live test calls using a commercial handset solution for HSDPA in March 2005. Nortel achieved the industry's first HSDPA call at 3.6 Mbps in December 2005, and industry-first UMTS-HSDPA call in the 900 MHz band in January 2006.
