DALLAS -- Nortel Networks* [NYSE/TSE: NT] announced the ability to provide integrated solutions for wireless operators that will seamlessly link existing and future Wireless Wide Area Networks (WWANs) with fast-emerging wireless 'hot spots,' also known as Wireless Local Area Networks (WLANs). Nortel Networks integrated WWAN/ WLAN technology will give GSM, GPRS, UMTS and CDMA wireless operators the opportunity to provide enterprises and consumers with a single 'sign on' and seamless service between 2G/3G networks and wireless hot spots. This solution will also give operators the capability to provide consolidated billing, authentication and security without the need to restructure existing network architectures. This technology will help enable mobile workers to establish 'virtual offices,' connect securely to corporate intranets, send and respond to e-mails, access the Web, download files, and conduct business from virtually any location. In addition, it will allow users to roam seamlessly between wireless 2G/3G and WLAN networks with uninterrupted access to the same Internet Protocol (IP) data services. The technology will also manage billing information across networks so that end users can receive one consolidated bill from their wireless operator. "As part of our Wireless Data Networks strategy, Nortel Networks has developed this comprehensive suite of solutions to allow wireless operators to offer secure WLAN hotspot connectivity as an extension to their existing wireless services," said Dave Murashige, vice president, strategic marketing, Wireless Networks, Nortel Networks. "The WLAN strategy we are announcing today demonstrates our commitment to helping operators create a mobile environment that delivers users compelling content and data services from any location. Our WLAN technology, coupled with our extensive experience in IP data networking, will position operators to increase revenue potential and reduce subscriber churn." As part of its integrated WWAN/WLAN offering, Nortel Networks is working with Mobility Network Systems, a leading supplier of carrier-class WLAN solutions, to provide comprehensive solutions that will enable GSM, GPRS and UMTS operators to integrate WLANs into their existing networks and service platforms using SIM and RADIUS technology. In interoperability testing conducted earlier this year, Mobility Networks ipRAN* technology was successfully integrated with Nortel Networks GSM, GPRS and UMTS core network infrastructure and products, including Home Location Register (HLR) and Nortel Networks Univity* GPRS Gateway Serving Node (GGSN).
