ORLANDO, Florida -- A new architecture for mobile networks, launched by Nokia Siemens Networks at CTIAWireless 2011, 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 networkresources through sharing and redistributing capacity based on user demand. NokiaSiemens Networks has also announced its innovative Flexi Multiradio Antenna Systemas part of the Liquid Radio architecture. The company expects to begin to deploy thisarchitecture during 2011.

“Liquids are unconstrained, streaming to fill any gap or space,” said Thorsten Robrecht, headof Network Systems product management, Nokia Siemens Networks. “In the same way, ourLiquid Radio architecture removes the constraints of traditional mobile broadband networksto address the ‘ebb and flow’ of traffic created by users’ movements across the network.”At the heart of Nokia Siemens Networks Liquid Radio is the ability to respond to the fluiddemands of today’s networks with a technique known as baseband pooling. This approachcentralizes the resources needed to undertake processing functions common to every basestation in a given area. Baseband pooling helps to achieve a more cost efficient sharing ofresources over a large geographical area.

Nokia Siemens Networks Flexi Multiradio Antenna System is based on active antennatechnology that combines antenna and radio part in one functional enclosure, built withdedicated power amplifiers for each antenna element. The active antenna allowsbeamforming – focusing a particular radio connection and directing it to a specific user – aswell as handling of multiple technologies in one unit. Together with other layers of coverageprovided by macro, pico and micro site configurations, beamforming allows capacity to bedirected exactly where the user requires it, delivering up to 65% capacity gain.
