Nortel Achieves First Simultaneous High-Speed Uplink, Downlink Mobile Calls Power of Combined HSUPA and HSDPA to be Demonstrated at 3GSM World Congress
Nortel* [NYSE/TSX: NT] 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 – planned to be repeated at next week’s 3GSM World Congress in Barcelona --uses Nortel’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.
This achievement illustrates the potential viability of next-generation wireless technologies for high-bandwidth applications between mobile devices such as VOIP, video streaming, real-time high-definition mobile gaming and large file exchange. High-speed uplinks are particularly valued by media agencies transferring high-definition images and video content from locations with no broadband wireline access.
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. In June 2005, Nortel became the first wireless network supplier to complete the TL9000 registration standard for Quality Management System Requirements and Measurements across its HSDPA, UMTS and GSM wireless infrastructure solutions. 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.
Nortel has worked with a number of wireless operators on HSDPA trials and deployments, including EDGE Wireless in the US, SKT and KTF in Korea, SOFTBANK Group's BB Mobile in Japan, mmO2, Orange, Vodafone (at CeBIT 2005 in Hanover, Germany), Partner Communications in Israel, and Mobilkom Austria.
