Nokia Siemens Networks Launches Mobile Network Architecture
By Anita Bora, TMCnet Contributor
Nokia Siemens Networks recently announced the launch of a new architecture for mobile networks at the CTIA (News - Alert) Wireless 2011. Nokia Siemens Networks is a global enabler of telecommunications services and solutions, which rankedfirst in the recent Vendor Matrix launched by ABI Research, a firm that analyzes the telecommunications and technology sectors.
This unique architecture will allow network capacity and coverage to flow to where it’s required the most. Known as Liquid Radio, the architecture enables cost effective usage of network resources by sharing and redistributing capacity based on user demand. As part of its Liquid Radio architecture, Nokia (News
- Alert) Siemens Networks also announced its Flexi Multiradio Antenna System.
Nokia Siemens Networks is one of the largest telecommunications hardware, software and professional services companies in the world, operating in 150 countries, and headquartered in Espoo Finland. The company is expected to begin deployment of this architecture in 2011.
Thorsten Robrecht, head of Network Systems product management, Nokia Siemens Networks (News - Alert) comments in a company statement: “Liquids are unconstrained, streaming to fill any gap or space. 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.”
At the heart of the Liquid Radio architecture, is a technique called baseband pooling, which is the ability to respond to the changing demands of today's networks. This approach centralizes the resources required to undertake processing functions that are common to base stations in a particular area. The main advantage of baseband pooling is cost efficiency over large geographical areas.
The 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, in addition to handling multiple technologies in one unit. Together ,with other layers of coverage provided by macro, pico and micro site configurations, beamforming achieves a 65 percent gain by allowing capacity to be directed exactly where the user requires it.
The Flexi Race, with its compact size, is seen as the next evolutionary step in miniaturization. It will form the basic element to build next generation active antennas and future products to build micro and pico cells. The Flexi Race is equipped with additional intelligence and scaling options required for these types of deployments.
Robrecht also added, “We foresee demand for network capacity increasing to up to 1 GB per user per day. Not only will this require substantial network investments, but also a unique combination of base station sites for wide area coverage complemented by Wifi and small, compact micro, pico and femto cells. 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 (News - Alert) and LTE-Advanced.”
With its broad offerings, Nokia Siemens Networks helps operators to build unified heterogeneous networks, thus reducing management complexity and allowing connectivity for different layers of the network in one unified network and user experience. This is achieved by the company’s Self Organizing Networks (SON) capability and its continuous evolution to fully support cognitive self learning and adaptive networks.
