Nokia Siemens Networks unveiled its “Single RAN Advanced” architecture for supporting the full range of air interface technologies from GSM up through LTE-Advanced using software defined radios.
Key components of Single RAN Advanced include a new highly powerful, compact and scalable Flexi Multiradio 10 Base Station. This base station will be 10 Gbps capable for high capacity cell sites. Single RAN Advanced also includes the Flexi Lite Base Station for micro and pico deployments, which are ideal for providing hotspot coverage in high traffic areas, and a Multicontroller platform for GSM and 3G.
Nokia Siemens Networks Flexi Base Station will also have the capability to reallocate radio frequencies for maximum efficiency. The 4.2 MHz technology can rapidly refarm HSPA to lower frequencies with less spectrum required. It also offers spectral efficiency features like Orthogonal Sub Channel in GSM.
Flexi BTS will also come with integrated IP transport interfaces. Flexi BTS will also feature a modular design and the ability to deployed outdoors, eliminating the need for shelter or huts with air conditioning.
Nokia Siemens Networks’ Flexi Multiradio 10 Base Station will be available for commercial deployment during 2011, while the Flexi Lite Base Station will become available for commercial use during the first half of 2012. The Multicontroller platform is already being used in customer trials.
“While network operators’ revenue opportunities have grown over the past few years, they also face newer challenges to further enhance network efficiency and simplify their networks,” said Thorsten Robrecht, head of Network Systems product management, Nokia Siemens Networks. “It has therefore become imperative for operators to smoothly migrate to newer technologies in support of their longer-term network strategy. Single RAN Advanced offers one access network with leading software features for multiple technologies, allowing operators to provide improved services at a competitive price.”http://www.nsn.com
