CDMA450 is a 3G solution of high value yet affordable

CDMA450 has been one of the skyrocketing sectors in the global wireless communication industry in the past few years. It has attracted keen interest in the industry. CDMA450 inherits all the technical and service advantages of the CDMA2000® system. It boasts wide coverage of the 450MHz spectrum and enables the building of a competitive 3G mobile network with complete service capabilities at the lowest cost, thus becoming a high-value-yet-affordable 3G solution for operators. In addition, CDMA450 is perfectly suited for the Wireless Local Loop (WLL) system of a fixed network, and for universal services.

Since 2003, CDMA450 has been a common choice of the 450MHz operators by virtue of its mature technologies and upbeat prospect, and achieved fast development in the past year. We believe that based on the merits of advanced technologies, distinctive network performance, diversified services and smooth evolution, CDMA450 will be preferred by more operators in more countries and regions.

Huawei’s leading role in the CDMA450 global market Huawei’s CDMA450 products have been widely used in nearly 20 countries worldwide, and put into large-scale commercial application in Russia, White Russia, Portugal, Indonesia, Pakistan, Uzbekistan, Ethiopia, etc. Currently, Huawei is in a fast growth period with sound interaction of technologies, products and markets, fully demonstrating the “high quality, cost effectiveness and excellent services” product features.

In Europe, INQUAM has selected Huawei as a global strategic partner, and Huawei provides basestation equipment for the national CDMA450 network of Radiomovel, INQUAM’s wholly-owned subsidiary in Portugal, which is the commercial debut of the CDMA450 system in Western Europe. In addition to basic voice services, this network will provide diversified data and multimedia services.

In December 2003, Mobilsel, an Indonesian CDMA operator, announced the commercial deployment of its CDMA450 network. Huawei provides the whole set of CDMA450 mobile network solutions for Mobilsel, including the Core Switching System, Wireless Access Basestation System, Network Management System and serial terminals. Mr. Martin, vice president of Mobisel, said: “We are very satisfied about all the indices of Huawei’s CDMA system, and hold faith in Huawei.” In South Africa, Ethiopia Telecom Company (ETC) selected Huawei as its strategic partner, and recruited Huawei to construct its CDMA2000 1X WLL network, where three cities have adopted the 450MHz CDMA WLL system.

Huawei is committed to maturing the CDMA450 industrial chain

Being an international telecom system equipment manufacturer whose products are prevalent in more than 50 countries and regions, the biggest telecom equipment supplier in China, and a leading CDMA450 supplier, Huawei injects huge investment in CDMA450 development, and cooperates with CDMA450 peers in the industry in an open manner with a view to rolling out the CDMA450 industrial chain. Huawei debuted the CDMA450 1xEV-DO service in Geneva jointly with Qualcomm, implemented the first CDMA450 international roaming between White Russia and Russia jointly with Lucent, and staged wide cooperations with terminal manufacturers such as Hyundai and Synertek.

In September 2002, Huawei joined the NMT450 Association. Being a member of the NMT450 Association (predecessor of International 450 Association, IA450 for short), Huawei is committed to boosting and maturing the CDMA450 industrial chain across the globe.

21~22 April 2004, the International CDMA450 Conference, hosted by Huawei and co-organized by IA450 and CDG, was held in Shenzhen. More than 250 attendees were present at the meeting, including CDMA450 operators, equipment suppliers and terminal manufacturers, Lehman Brothers and press from all over the world. The CDMA450 International Conference was held for the first time at the proposal of Huawei. At the meeting, the attendees exchanged their views about the global market trend of CDMA450, network operation experience, and new technologies. This conference turned out to be a great success.

Catering to customer requirements, commanding recognition of the industry

Huawei has been developing CDMA products since 1995, and the accumulated investments in that sector total more than one billion yuan. The rapid development of Huawei’s CDMA is attributable to the ongoing investment and the customer-oriented optimum solution. Winning by strength helps Huawei bear fruits across the globe, and fulfill the goal of “Lead a field once you are engaged in it”.

Huawei has been committed to the technical research of the 450MHz band since 1996, and launched the 450MHz-based analog wireless access network product – ETS450, which claims more than 90% market share of the Chinese 450MHz wireless access market. Since 2002, Huawei has applied the CDMA technologies to the 450MHz band, and launched CDMA450 products together with its partners. Huawei has been propelling the maturity of the CDMA450 industrial chain to meet the actual requirements of network operators worldwide. In response to the network construction and operation requirements of the customer, Huawei has launched the end-to-end solution, including infrastructure, service platform, mobile station, and fixed station terminals. Huawei’s CDMA450 solution is based on state-of-the-art broadband platforms, which ensure smooth upgrading to the future versions of IMT-2000. In order to meet the requirements of different customers, Huawei releases a series of special service solutions, and works out satisfying solutions to both wireless local call in urban areas and universal services in hinterlands, both IS-95 network upgrading and NMT450/TDMA network transformation, both broadband mobile data services and enterprise private network construction.

In terms of product, Huawei keeps reinforcing and optimizing the customization of the CDMA system, and launches the basestations compatible at multiple bands (450MHZ/800MHz/1900MHz/2100MHz) and suitable for indoor and outdoor installation, and enables the operators to deploy the network in a fast and cost-effective way even without equipment room. The mobile stations and fixed stations of different styles at different bands are launched to better support the network operation.

Huawei’s CDMA2000 1X product is based on the cutting-edge design concept of whole range broadband platform and digital transceiver. The practice has evidenced that Huawei’s CDMA system is a pacesetter in being backward compatible with 1xEV. In February 2003, Huawei won the first place in shortlist test at MCC organized by the Russian Posts and Telecommunications Industry, and implemented the international roaming between CDMA450 commercial networks for the first time in the world.

In terms of terminals, Huawei provides the operators with high quality down-, medium- and up-market mobile stations, and the terminal type and phone type fixed terminals, which help the mobile and fixed operators to expand the user group.

In terms of service, Huawei provides a full-blown, complete set of mobile intelligent network services, SMS, BOSS, and PTT solutions, thus strongly supporting the operators to solicit users.


A Huawei officer in charge of the wireless product line discloses that Huawei will continue to make huge investments in the CDMA sector, catering to customer needs, and providing the best solutions and services for the customers.
