Nokia Siemens Networks Improves Network Efficiency with "Liquid Radio"

A new architecture for mobile networks, launched by Nokia Siemens Networks, is able to direct mobile broadband capacity to where it is needed most. Known as "Liquid Radio", the approach enables a more economic use of network resources through sharing and redistributing capacity based on user demand. Nokia Siemens Networks has also announced its Flexi Multiradio Antenna System as part of the Liquid Radio architecture.

The company expects to start deploying the new platforms during 2011.

At the heart of Nokia Siemens Networks Liquid Radio is the ability to respond to the demands of networks with a technique known as baseband pooling. This approach centralizes the resources needed to undertake processing functions common to every base station in a given area. Baseband pooling helps to achieve a more cost efficient sharing of resources over a large geographical area.

Nokia Siemens Networks Flexi Multiradio Antenna System is based on active antenna technology that combines antenna and radio part in one functional enclosure, built with dedicated power amplifiers for each antenna element. The active antenna allows beamforming - focusing a particular radio connection and directing it to a specific user - as well as handling of multiple technologies in one unit.

Together with other layers of coverage provided by macro, pico and micro site configurations, beamforming allows capacity to be directed exactly where the user requires it, delivering up to 65% capacity gain.
