New software frees GSM spectrum to deliver mobile broadband #MWC12

Liquid Radio GSM Software increases 2G efficiency, can double 3G and 4G data rates
360 operators in 140 countries serving 3 billion GSM subscribers can now allocate their network resources more fluidly with Nokia Siemens Networks’ Liquid Radio GSM software suite. When used with the company’s Flexi Multiradio base stations, the software suite makes more efficient use of the spectrum allocated to GSM services, while improving network quality. This frees up valuable spectrum to either increase GSM capacity or to deliver 3G and 4G mobile broadband at higher data rates.
Operators re-farming GSM frequency to support 3G and 4G rollouts can free up to 30% of their spectrum, reduce total cost of ownership by 20% and potentially double their average 3G and 4G data speeds. GSM only network operators can potentially quadruple their capacity while lowering energy costs by 14%.
The software suite is commercially available globally.
“Our multiradio equipment helps operators manage the unpredictable fluctuations in network coverage and capacity demands as mobile broadband users switch across applications and devices on-the-move,” said Thorsten Robrecht, head of Network Systems product management, Nokia Siemens Networks. “With the new software suite, operators can make their network fluid, further optimize their Flexi Multiradio Base Station radio equipment, improve network efficiency and get more out of their spectrum. Moreover, with re-farming, rollout of mobile broadband services is easier, more cost efficient, and this can potentially help increase revenues.”
The Liquid Radio* based GSM software suite comprises of five Nokia Siemens Networks’ innovated features**. Mobile operators can deploy these along with the company’s award winning Flexi Multiradio Base Station family and Multicontroller for improved coverage and adequate capacity, and faster, more cost efficient evolution of mobile broadband.
Nokia Siemens Networks also offers planning and implementation services for re-farming 3G on 900 MHz and 4G LTE on 1800 MHz to help operators increase network capacity and improve network performance. Having supported over 65% of commercial 3G 900 MHz networks, the company is a leader in re-farming services***.

*Nokia Siemens Networks’ Liquid Radio architecture self-adapts network capacity and coverage according to demand to deliver significant capacity gains. Over 60 operators including China Mobile, Vodafone India, Claro Ecuador, Vodacom Tanzania and AIS Thailand have already started the evolution to Liquid Radio.
**Nokia Siemens Networks‘ Liquid Radio GSM software suite comprises of five features, all of which are the company‘s innovations. Features that compress the GSM traffic and reduce the number of traffic channels to transmit the same amount of voice and data include Orthogonal Sub Channel (OSC), Smart Resource Adaptation (SRA), Precise Paging (PP), Dynamic Frequency and Channel Allocation (DFCA).
The new Flexible MCPA (Multi Carrier Power Amplifier) Tx power pooling feature effectively enables dynamic, rather than static sharing of radio resources of GSM carriers, allocating the resources precisely and exactly where the usage is. This reduces the output power needed for GSM, making it more efficient. In case of refarming, this frees more capacity for 3G or 4G and combined with the other features, enables up to double the average 3G or 4G throughput.
***Nokia Siemens Networks currently has 23 references for its professional re-farming services. Operators can expect improved performance, with up to 25% improvement in Drop Call Rate (DCR) and more than 30% increase in data throughput
