Telecom Lead Europe: Nokia Siemens Networks has unveiled Liquid Radio WCDMA software suite to boost performance of existing WCDMA networks.
The advanced software combines three powerful and complementary features designed to deliver faster data uploads and extract the full benefit from network resources and smartphone capabilities.
The three features are Continuous Packet Connectivity (CPC), Multi-Band Load Balancing (MBLB) and Quality of Service (QoS) differentiation.
The feature set helps operators improve customer satisfaction and cut churn while increasing revenue from greater 3G availability.
Continuous Packet Connectivity helps operators use radio network resources more efficiently by reducing interference. It does this by turning off transmitters in mobile devices when no data needs to be sent. CPC enables the network to support five times more users and four times more uplink throughput. As a result, operators can enable fast data uploads and provide a longer battery life for users’ smart devices.
Many WCDMA networks are multi-layered – meaning that operators are using two or more frequency bands such as 900 MHz and 2100 MHz – to provide the 3G service. By balancing traffic evenly between an operator’s available spectrum, Multi-Band Load Balancing prevents one frequency band from becoming overloaded while another is underused. This ensures optimal use of the network capacity across all available 3G bands and helps operators fully benefit from their investments.
MBLB creates up to 20 percent more available network capacity from existing hardware resources. In trials in London during summer 2012, an operator used MBLB and corresponding services to successfully balance data traffic in its network and thus enable higher data speeds for subscribers.
In cases where traffic begins to exceed network capacity, even after CPC and MBLB have been implemented, a third feature of the WCDMA software suite, QoS differentiation, comes into play. As well as supporting time critical data traffic, QoS differentiation makes it possible to have up to 50 percent more users per network cell, which can reduce operational costs by 30 percent. Overall, the feature helps raise efficiency, reduce wasted capacity and improve the user experience.
“Our WCDMA software suite gives operators the tools they need to build outstanding, personalized solutions for their subscribers while boosting network performance, capacity and quality at the same time,” said Keith Sutton, head of the WCDMA business line, Nokia Siemens Networks. “This way, they can meet users’ demands for high-quality high‑performance services.”
