Nokia Siemens Networks has made the evolution path from 2G and 3G to LTE faster, greener and more cost-effective with the launch of Flexi Multiradio Base Station. Building on the company’s Flexi Base Station platform, the new Multiradio Flexi expands its supported technologies to cover GSM/EDGE, WCDMA/HSPA and LTE – all running concurrently in a single unit.
Flexi Multiradio Base Station meets the needs of new and existing 2G and 3G operators who can use their existing infrastructure to deploy new network-wide technologies via simple software upgrade to 3G or LTE. The flexibility of a true multiradio base station removes the risk from balancing investments made in 2G, 3G and LTE, providing operators with future-proof options. The new Multiradio Flexi is also backward compatible with current Flexi Base Station, enabling capacity upgrades to existing Base Station sites.The product also fits CDMA operators who intend to migrate to WCDMA/HSPA or LTE.
For operators coping with cost challenges, running multiple radio technologies in a single Base Station means reduced OPEX from fewer site visits, simplified logistics, reduced maintenance and a smaller requirement for trained staff. The possibility to reuse GSM sites for WCDMA and HSPA also delivers savings from reduced rental costs and maximized reuse of existing infrastructure.
Superior energy efficiency – a key feature of Flexi Base Stations – is further improved in Flexi Multiradio. According to the company, the new Base Station has the lowest energy consumption in the market. An average 3 sector Base Station site running simultaneously GSM/EDGE and WCDMA/HSPA consumes as little as 790W, whilst pushing a 60W output per sector for maximum capacity and coverage. The small and lightweight product is also rugged enough for outdoor use without shelters or air conditioning, further minimising their environmental impact.
Flexi Multiradio Base Station features built-in IP/Ethernet connectivity for a unified transport network for the Single RAN. Operators can also benefit from using the common NetAct network management system for planning, optimising and operating the Single RAN. NetAct Optimizer enables easy and high quality refarming of WCDMA or LTE in current GSM 900 MHz frequency band.
Deployments of this new Flexi Multiradio Base Station will start from the beginning of 2010 onwards.
Nokia Siemens Networks also introduces its new Multicontroller platform for radio access, a further step towards a joint 2G/3G evolution. This will be the basis for its future radio network controller products, including GSM and WCDMA. The Nokia Siemens Networks Multicontroller is adaptable to various traffic mixes and is scalable with growing capacity up to 35 Gbps. First deployments of Multicontroller are starting from the second half of 2010 onwards.
