By this summer, Sky Link plans to expand the coverage of its Lucent-supplied CDMA2000 1.EV-DO network to the
The network supports mobile high-speed data services at speeds of up to 2.4 Mb/s, and this project continues the establishment of the unified federal CDMA450 network under the Sky Link brand. It also includes both the regional expansion and technical upgrade of the network. Following the deployment, both local and roaming subscribers in these regions will be able to access reliable, high-quality, secure voice and data services, including mobile video, mobile office solutions, and other broadband applications.
Sky Link's EV-DO technology was deployed in Moscow and St Petersburg in 2005. The experience of customers in other countries that have deployed 1xEV-DO networks demonstrates a clear demand for mobile high-speed data services. For this year's project Lucent is supplying its CDMA2000 solution for the 450Hz frequency band, including its Mobile Switching Centre (MSC) and new Modular Cell 4.0 Compact base stations, which offer a smaller footprint and more cost-efficient power consumption. The Lucent CDMA2000 1xEV-DO Radio Network Controller (RNC) is intended to ensure the flexibility and scalability of network radio resources management. Lucent Worldwide Services will provide network deployment, training and support services.
In the near future, Sky Link is planning a migration to an enhanced version of CDMA2000 1xEV-DO called Revision A, which increases the efficiency, data speeds and capacity of existing EV-DO networks. CDMA2000 1xEV-DO Revision A enables users to receive data (forward link) at speeds of theoretically up to 3.1Mb/s and to send data (reverse link) at speeds of theoretically up to 1.8Mb/s. These increased reverse link data speeds reduce data latency and will enable mobile operators to deliver VoIP and other multimedia services on CDMA2000 networks in the future.
