The wireless network solution for Nortel Networks integrates wireless, optical, and IP technologies to achieve "forever online" access, enabling users to use their personal portable wireless devices "anytime, anywhere" in accessing multimedia content and services. These technologies provide the basis for wireless internet, mobile commerce, wireless video streaming, location-based services, and other new value-added wireless services.
Nortel Network's Univity Internet Base Station (IBTS) is the industry's first base station to support all wireless mobile standards, including UMTS and CDMA2000, with a single economy platform; The solution of Nortel Network combines the advantages of IP backbone with wireless technology, and realizes the optimization of network system. The Nortel Network is based on the core network of packet switching, consisting of the industry-leading Passport data exchange platform and the Shasta packet switching gateway, which can support all wireless, fixed, and interconnected services.
With the development of wireless data services and the increasing number of users, Nortel Networks can improve their wireless network offerings, improve network efficiency, drive economic efficiency and increase revenue to suit any operator's existing wireless network and 3G Evolution strategy.
Nortel Networks use a number of different wireless technologies, including CDMA, CDMA2000 1X, 1xev-do, 1XEV-DV, TDMA, GSM, GPRS, Edge and UMTS, each with a clear path to upgrade to next-generation networks, To meet the needs of global operators and users.
Nortel Network CDMA Access series is based on the powerful advantages of base station Wireless transceiver System (BTS) and Base station controller (BSC). The BTS series of Nortel Networks can run both IS-95 and CDMA2000, and can support all CDMA2000 1X, 1xEV, IS-95, 800MHz and 1900MHz on a single BTS. The most important feature of Nortel Network is the smooth transition of the existing second-generation network, which fully protects the original investment of the operator.
Nortel Network 1xev-do solution based on Nortel Network leading CDMA2000 1X technology, can be upgraded by the Nortel Network CDMA Metro Cell Base Station implementation. Because cdma1xev-do can provide a high speed and capacity, CDMA operators can provide more users with video and audio streaming, wireless web browsing and interactive games and other new services, so that they can develop new business at a lower cost, access to new business growth.
Nortel Network UMTS solution consists of Nortel Network Univity Ibts, Passport, preside and Shasta. The Ibts of Nortel Network has high capacity and large density, can reduce the cost of network deployment, and can help operators to improve network capacity and coverage, thus reducing the cost of hardware input. With a distributed architecture, the UMTS solution can also reduce the cost of ownership. Nortel Network UMTS based on plug-and-play expansion theory, it is easy to develop from the initial coverage solution to the full use of existing frequencies to provide services, but also in different parts and different carriers dynamic distribution of capacity resources. Nortel Network UMTS can also help operators smooth migration from existing ATM networks to IP and MPLS networks, enabling operators to efficiently utilize existing frequencies to ensure their technology investments.
From the perspective of network architecture, the advantages of Nortel Network 3G UMTS Network are: The network level is reduced, the use of virtual one or two level network, network reliability enhancement, easy to maintain, can facilitate the introduction of SIP multimedia services, in the relevant Business Server cluster into the SIP server, Mobile users can enjoy the R5 real-time multimedia service on the R99 or R4 network, and enhance the operators ' competitiveness; because of the way of the Business Server dicing, from the point of view of the business deployment, the time of new business deployment is shortened and the cost is reduced. As a result of the use of statistical multiplexing transmission mode, compared to the 64K static circuit mode, transmission efficiency is improved, the network resource share is reduced.
From the point of view of business assurance, the advantage of UMTS is that the multi-service bearer network can improve the voice service quality of UMTS network by using the fixed-length grouping mode to carry the voice packet, with the excellent service quality assurance ability of the network, the delay, jitter and integrality of the voice packet packet can be guaranteed to some extent. In order to ensure the bandwidth and real-time transmission of the packet packet, the multicast network has unique advantages from the view of guaranteeing the time delay and the quality of service and ensuring the real-time traffic in the packet network. At the same time, from the point of view of business level and bandwidth guarantee, multi-service bearer network has great advantages.
