Nortel CDMA Trials> From the November 30, 1998 issue of Wireless Week Nortel Tests CDMA Data Service By Peggy Albright Nortel Networks is conducting live field trials of a new circuit-switched data service that will give customers on code division multiple access networks mobile access to the Internet. "This is the first data service available for CDMA," said Brad Fink, Nortel's senior manager for wireless data. "This is the place that we and the industry need to start to get applications deployed." Fink said widespread deployment of the service should be available in 1999. The technology, which is based on Interim Standard 707, can be deployed on any IS-95 network that uses Nortel's DMS-MTX digital mobile switching systems, via a software enhancement that is installed at each switch. The service will enable carriers to offer mobile office applications for both voice and data, including the use of handset-based thin browsers such as Unwired Planet's UP.Link platform. Along with the IS-707-based software, Nortel offers an optional "FastConnect" enhancement that enables mobile-originated calls to bypass the public voice telephone network and connect directly to packet data networks. The company said this capability significantly reduces connect time by eliminating the need for a modem pool on the receiving side and providing direct Internet Protocol access for sending and receiving e-mail and faxes. Nortel said it is testing the service under live field conditions with Canada's Bell Mobility and with other selected carriers. The company also is working with Bell Mobility at Nortel's Wireless Internet Lab in Dallas, to identify applications the carrier can run over the data transport service. Barry Herbert, Nortel's multimedia business development manager, said part of the Wireless Internet Lab's objective is to develop capabilities to enhance the performance of IS-707. The standard offers data services at 14.4 kilobits per second but Nortel expects to push that capability to offer speeds of 57.6 kbps on 14.4 kbps equipment. "The idea here is to use various technologies ... such as tuning of protocols for wireless networks, intelligent compression of the content and filtering of graphics, which are particularly intensive in Web sites, [to reduce] the number of bytes that need to be transmitted," Herbert said. Additional high-speed wireless data technologies that could become available next year for CDMA carriers include IS-95B, which will allow 64 kbps data speeds for both circuit-switched and packet data services, according to the CDMA Development Group. The first phase of third-generation cdma2000, referred to as 1XRTT, will allow up to 144 kbps circuit and packet data services. One of its key attributes is that it can be deployed in an existing cdmaOne 5 MHz channel to double a network's voice capacity. Last week at the CDG's Americas Congress, Bell Atlantic Mobile Inc. announced that it is testing Lucent Technologies 1XRTT equipment, with plans to deploy commercial services by 2000. Sprint PCS also said that it will trial Lucent's 1XRTT services by the end of this year. \| Home Page \| Site Map \| Search Archive \| PowerSearch \| \| International \| Wireless Web Sites \| Hot Stories \| Please send comments and suggestions on this Web site to jcollins@chilton.net Wireless Week, 600 S.
