Nokia Siemens Networks Unveils New Architecture for Mobile Networks

Nokia Siemens Networks, a provider of telecom infrastructure equipment and solutions, announced the launch of Liquid Radio, a new architecture for mobile networks.

Liquid Radio has the capability to direct mobile broadband capacity to where it is needed most. It also enables economic use of network resources through sharing and redistributing capacity based on user demand.

“Liquids are unconstrained, streaming to fill any gap or space,” said Thorsten Robrecht, head of Network Systems product management, Nokia Siemens Networks, in a statement. “In the same way, our Liquid Radio architecture removes the constraints of traditional mobile broadband networks to address the ‘ebb and flow’ of traffic created by users’ movements across the network.”

Liquid Radio is designed to respond to the fluid demands of networks with baseband pooling technique. The baseband pooling helps in centralizing the resources to undertake processing functions of base stations. With baseband pooling, operators can achieve a more cost efficient sharing of resources over a large geographical area.

Nokia Siemens Networks also announced its innovative Flexi Multiradio Antenna System as part of the Liquid Radio architecture. The company is planning to deploy this architecture this year.

Flexi Multiradio Antenna System is based on active antenna technology combining antenna and radio part in one functional enclosure. The active antenna allows beamforming focusing a particular radio connection and directing it to a specific user.

Beamforming offers direction where the capacity is required. Together with other layers of coverage provided by macro, pico and micro site configurations, beamforming delivers up to 65 percent capacity gain.

The Flexi Race will be the basic element to build active antennas and future products to build micro and pico cells. The compact size enables the Flexi Race to equip with intelligence and scaling options required for deployments.

Recently, Nokia Siemens Networks announced it signed a five-year managed services contract with Vodacom Tanzania to improve its service quality. Apart from managing, operating and maintaining Vodacom's network in eastern Africa, Nokia Siemens Networks will also take care of its Network Management Center and operations across the radio, transmission and core networks.
