NSN – Flexi Multiradio Base Stations

At one end the demand of mobile broadband is increasing and so is the need of 3G and B3G (Beyond 3G), where as at the other end operators as well as consumers have shown reluctance to go 3G. Operators resist in the deployment of 3G as they have invested heavily in existing air-interface infrastructure, while for consumers the cost of using 3G services is high.

As we had discussed earlier in the Evolution towards HSDPA, the migration strategy along the road to the 3G and beyond should be “soft” network evolution that does not render existing installations superfluous. The solutions to this comes as NSN unveils plans for Flexi Multiradio base stations.

As reported in a press release,

Nokia Siemens Networks has today made the evolution path from 2G and 3G to LTE faster, greener and more cost-effective than ever with the launch of Flexi Multiradio Base Station. Building on the company’s market leading 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.

“Flexi Multiradio Base Station makes network evolution faster, greener and more cost-efficient than ever, and this launch makes Nokia Siemens Networks the only vendor which enables future technology evolution steps exactly with the same hardware without radio technology specific boards. Thanks to the industry’s highest degree of integration, Flexi Multiradio Base Station is able to provide three technologies in one compact 3 sector Base Station of less than 75 liters”, said Marc Rouanne, head of the company’s Radio Access business.

Superior energy efficiency – a key feature of Flexi Base Stations – is further improved in Flexi Multiradio. 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 an impressive 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.

“We are very pleased to see Nokia Siemens Networks take concrete steps towards fulfilment of the targets agreed in the context of WWF’s Climate Savers programme” said Jean-Paul Jeanrenaud, Director of Corporate Relations at WWF International. “This is a good example of how technological innovation can contribute to improved energy efficiency and profitability, while reducing a company’s ecological footprint. The fight against climate change requires all the ingenuity and commitment that the corporate sector has to offer”.

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. For example, 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.

    PTA will distribute the 3G spectrum on auction basis!

    this place is quite cool to learn telecomm tech…i have one query!!!
    PTA has got 3MHz of spectral range for 3G. Why PTA has got just 35Mhz??? we have seen that in 2G whole spectral range of GSM is under control of PTA… i want to know who distribute spectrum of 3G and on what basis!!!
