Nokia Siemens Networks has completed network analysis, optimisation and upgrades to O2’s base stations across London.
Working with O2, Nokia Siemens Networks monitored and analysed the data and signalling behaviour of different smart devices connected to the mobile network. The methodology provided information on the impact of these devices on different network elements.
The information, combined with traffic growth forecasts, was used to establish a capacity improvement project, upgrading only the network elements and modules identified as bottlenecks for current and future performance within O2’s London network.
The upgrade included enhancing the signalling capacity of the network as well as modernising the network with Nokia Siemens Networks’ flexi multiradio base stations. The flexi multiradio base station is an energy efficient base station with a compact, weatherproof, modular design.
It has been combined with Nokia Siemens Networks’ high-performance site solution that increases network capacity by doubling the number of mobile sectors from three to six in each base station’s area of coverage.
This deployment of 3G six-sector sites was recognised by the Global Telecoms Business Innovation Awards 2010. The six-sector site deployment provides improved capacity resulting in the ability to carry significantly more voice and data calls in O2’s network.
“There is unprecedented demand on mobile networks, particularly in dense urban areas,” said O2 UK’s head of technology Nigel Purdy.
“Nokia Siemens Networks reacted swiftly to understand the challenges being placed on our network, and then implemented an effective upgrade to enhance the smartphone experience for our customers. This has resulted in a better use of network resources, minimised traffic loss and enhanced the experience of smartphone users.”
Nokia Siemens Networks said the upgrade also helps conserve smartphone battery life while decreasing signalling load on the network, adding that it is the only mobile network equipment supplier to have successfully implemented a technology that achieves such benefits.
“Thanks to our partnership over the last decade with O2, we worked closely to keep pace with booming smartphone demand and to ensure that O2 UK can cost-efficiently enhance their subscriber experience,” said Nokia Siemens Networks customer team head Pete Mitchell.
