Nokia Liquid Radio Architecture Launched

Nokia Siemens Networks launched a new architecture for mobile networks, named Nokia Liquid Radio architecture. Nokia 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 enables a more economic use of network resources through sharing and redistributing capacity based on user demand.

At the heart of Nokia Siemens Networks Liquid Radio is the ability to respond to the fluid demands of today’s 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.

The Flexi Race is the next evolutionary step in miniaturization. It will be the basic element to build next generation active antennas and future products to build micro and pico cells. Due to its compact size, the Flexi Race is equipped with additional intelligence and scaling options required for this type of deployments.

With its unique, broad product and professional services portfolio, Nokia Siemens Networks helps operators to build unified heterogeneous networks. This approach reduces management complexity and allows connectivity for different layers of the network in one unified network and user experience. This is orchestrated by the company’s Self Organizing Networks (SON) capability and its continuous evolution to fully support cognitive self learning and adaptive networks.

Nokia Siemens Networks Liquid Radio ensures that existing network investments are fully leveraged and that future investments deliver the return necessary to support today’s pressing challenge of maintaining and transitioning GSM, evolving 3G and introducing LTE and LTE-Advanced.

Nokia Siemens Networks‘ Liquid Radio architecture comprises three key elements:

Baseband pooling achieved via Nokia Siemens Networks‘ recently launched Flexi Multiradio 10 Base Station enables centralized pools of over 10 Gbps baseband capacity to manage up to 100 cells dynamically via smart scheduling algorithms.

The new Flexi Multiradio Antenna System provides true active antennas and complements the market leading Flexi Multiradio Base Station family. With availability starting end of 2011, Flexi Multiradio Antenna System is the only architecture based on several distributed radio frequency components integrated in the antenna housing to genuinely cooperate as a single entity to enable advanced features like beamforming. Beamforming provides additional capacity exactly where it is needed, allowing up to 65% capacity gain.

Unified heterogeneous networks enable various network layers to be used as a logically unified network with automated management, seamless interworking and uncompromised quality of experience to the user. As modern mobile networks continue to carry most of the traffic for mobile broadband in the future, they are getting more complex with several bands and mobile technologies (like LTE, HSPA+, Long Term HSPA Evolution) and the use of smaller cells like micro, pico and femtocells. Also, alternative technologies like 802.1x WiFi are increasingly being used for mobile broadband capacity enhancement as well as the more traditional in-building coverage.
