NORTEL NETWORKS: NEW SOLUTION FOR FASTER UMTS WIRELESS DATA SERVICE.Nortel Networks (Nortel Networks Limited, Brampton, Ontario, www.nortelnetworks.com) A world leader in telecommunications products, which includes switching, wireless and broadband systems for service providers and carriers, telephones and systems for residential and business users, computer telephony (NYSE NYSE See: New York Stock Exchange :NT)(TSE See Tokyo Stock Exchange. TSE 1. See Tokyo Stock Exchange (TSE). 2. See Toronto Stock Exchange (TSE). :NT.) recently announced commercial availability of a new solution designed to enable service providers to offer significantly faster performance for wireless data users with no impact on service coverage. Called 'intelligent asymmetric radio solution,' this new offering combines Nortel Networks expertise in 'tuning' wireless networks based on CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. digital technology with the industry's highest-power UMTS (Universal Mobile Telecommunications System) The GSM implementation of the 3G wireless phone system. Part of IMT-2000, UMTS provides service in the 2 GHz band and offers global roaming and personalized features. radio base station to increase downlink capacity from 30 to 100 percent. This is expected to enable data downloads at speeds up to 384 kilobits per second (unit) kilobits per second - (kbps, kb/s) A unit of data rate where 1 kb/s = 1000 bits per second. This contrasts with units of storage where 1 Kb = 1024 bits (note upper case K). (kbps)-- six times faster than the 64 kbps speed commonly anticipated from initial UMTS service. "Unlike voice, most data services are asymmetric in nature - meaning that people download more information than they send," said Jason Chapman, senior analyst, Mobile Communications, Gartner. "As opposed to traditional GSM symmetric engineering where uplink and downlink capacity are equal, UMTS - based on W-CDMA See WCDMA. technology - allows asymmetric engineering. Operators need to consider this when dimensioning their UMTS networks Beginning in 2003 under the name 3, Hutchison Whampoa, a large port operator, has gradually launched their startup UMTS networks worldwide including Australia, Austria, Denmark, Hong Kong, Italy, United Kingdom, Ireland and Sweden. , as correctly estimating the uplink (terminal to base station) data rate will dramatically decrease the number of radio base stations." A compilation of industry analyst projections indicates that the volume of data downloaded to wireless devices will reach approximately 20 trillion bits per day by year-end 2005 - roughly equal to 2,500 music CDs, three million photographs, or one billion e-mail messages. That compares with projections of just two trillion bits of uploaded data per day by year-end 2005. "Nortel Networks can help position service providers to receive a return on investment from day one by enabling them to stimulate user demand with compelling data services while minimizing radio infrastructure costs," said Scott Wickware, director, UMTS Product Solutions, Nortel Networks. "The extra power provided by our UMTS Internet base station, combined with our long-term experience in both data and CDMA, gives us the tool sets needed to offer such efficient use of the spectrum." Industry analysts expect faster downloads to stimulate user demand for a wide range of wireless services, including Web browsing, streaming music and video, multimedia messaging, e-mail, banking and travel reservations. With Nortel Networks intelligent asymmetric radio solution, UMTS service providers will be positioned to offer premium users significantly faster downloads - like 384 kbps for MP3 music files, or 30 seconds for a 50-page document - while making and receiving calls, using no more radio coverage than required for a symmetric 64 kbps network. Nortel Networks is an industry leader and innovator focused on transforming how the world communicates and exchanges information.
