Nokia Siemens Networks (NSN) has announced in a press release that it has completed the implementation of a 3G network expansion for Telefonica that increases coverage, improves service quality, and reduces costs of the operator’s Spanish network. Via the project, coverage has been improved by ‘more than 25%’ in dense urban areas, whilst other improvements have been made to energy efficiency and environmental impact. With the implementation of NSN’s 3G Flexi Base Station, Telefonica expects to reduce CO2 emissions by up to 9,500 tonnes per year. NSN also provided network and services managing, monitoring and analysing.
Nokia Siemens Networks (NSN) has launched a new base station that will support GSM/EDGE, WCDMA/HSPA and LTE in a single unit. The vendor said the new multi-radio base station – part of its ‘Flexi’ range – is targeted at existing 2G and 3G operators that are looking for a simple software upgrade to next generation mobile technologies; it is also aimed at CDMA operators planning to migrate to WCDMA/HSPA or LTE. NSN claimed that running multiple radio technologies in a single base station would cut costs as it maximises the re-use of existing infrastructure, and requires fewer site visits and maintenance.
NSN also talked up the new product’s green credentials, claiming the base station has the lowest energy consumption in the market. It said that an average three sector base station site running GSM/EDGE and WCDMA/HSPA simultaneously would consume as little as 790W. The new base stations will start being deployed at the beginning of 2010.
West African cellco Africell has contracted Nokia Siemens Networks (NSN) to deploy a mobile softswitching solution in its GSM networks in Gambia and Sierra Leone. The implementation is aimed at increasing efficiency by reducing operating expenses, while meeting subscribers’ growing demands and accelerating the deployment of new services. ‘The development of our core network is crucial to Africell’s future success as our call traffic continues to increase. Implementing NSN’s 3GPP Release 4 architecture will improve our overall network capacity in order to optimise the network resources providing state-of-the-art services to our customers,’ said Ziad Dalloul, CEO for Lintel Group, Africell’s holding company. The contract follows on from NSN’s expansion of radio and core mobile networks for the Gambian and Sierra Leone units.
According to The South China Post, five firms have won significant contracts from China Unicom in the tender for the deployment of W-CDMA infrastructure. The winners have been announced as Huawei, Ericsson, ZTE, Nokia Siemens Networks and Alcatel-Lucent all winning a share of the spoils. The results were released in the form of percentages awarded to various equipment suppliers: Huawei, which has a partnership with Motorola, was the largest winner with a 30.6% share of the 70,000 base station deployment; Ericsson which partners Fiberhome Telecommunication Technologies and Guangzhou New Postcom Equipment won a 26.5% share; ZTE won 21.5%; Nokia Siemens Networks 11.1%; and Alcatel-Shanghai Bell 10.2%.
China Unicom plans to deploy 3G networks in 55 cities in the first half of this year, spending RMB30 billion (USD4.39 billion), and 280 cities by the end of 2009, at a cost of RMB60 billion. The firm is targeting the completion of the first flagship city networks by 17 April and the first commercial network launches on 17 May 2009, the paper says.
For the first time in the world, four calls have been carried in one GSM radio timeslot. This significant step in GSM evolution path was taken today by Nokia Siemens Networks who successfully completed a drive test for the Orthogonal Sub Channel (OSC), that doubles the voice capacity of GSM radio network.This successful demonstration opens up a profitable growth path for operators, evolving their networks to a new level of efficiency with minimized CAPEX and OPEX. This is made possible by a software upgrade to existing Flexi EDGE Base Station and Base Station Controller. OSC is fully interoperable with existing handsets, so it promises immediate cost saving for operators, said Prashant Agnihotri, Head of GSM/EDGE product management, Nokia Siemens Networks.
With OSC, operators can gain more capacity from the same base station hardware, meaning fewer base station sites are needed in network rollouts and capacity extensions, which in turn saves energy and decreases the CO2 emissions.The OSC demonstration was conducted as a drive test using four handsets sharing only one radio timeslot and without compromising the call quality. The demonstration with existing commercially available GSM handsets was the first one of its kind in the world, strengthening Nokia Siemens Networks’ leadership in GSM/EDGE radio technology.
Tata Teleservices Ltd. is all set to go for a domestic GSM launch by the end of January. TTSL said that new entrants to India’s already crowded GSM market will likely face challenges in gaining subscribers and market share. Tata’s Managing Director, Anil Sardana, said, the company is a long term player in a market which is adding more than 8 million users a month.
Tata Teleservices plans to use part of the funds raised from the sale of a 49% stake in its tower arm for its GSM operations, in which the company intends to invest about $2 billion, added Sardana.
“All equipment has been ordered for all circles. Transmission is ready for all circles. Orders have been placed with NSN (Nokia Siemens Networks), Huawei (Technologies Co.) and ZTE (Corp.), for core telecom equipment, and NEC (Corp) for transmission,” Sardana further said.
