O2 Upgrades London Network with NSN

O2 has undertaken an upgrade of its network across London in partnership with Nokia Siemens Networks.

NSN said that it monitored and analyzed the data and signaling behavior of different smart devices connected to the O2 mobile network in order to gauge the impact of these devices on different network elements. This insight, 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 signaling capacity of the network as well as modernizing the network with Nokia Siemens Networks' Flexi Multiradio Base Stations. The companies said this recent deployment of 3G six-sector sites was recognized by 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.

  • In February 2010, BT Wholesale was awarded a five year contract to consolidate O2's mobile and fixed core networks in the UK into one network running on top of BT's 21st Century Network (21CN) infrastructure. BT Wholesale already provides a range of services to O2 including core network management support for O2's mobile customers as well as a managed network service that is enabling O2 to serve the UK business market with fixed and broadband services. This new agreement will further ties between the companies. O2 is a division of Telef√≥nica.

  • Telef√≥nica O2 UK has 21.4 million mobile customers and over 600,000 fixed broadband customers as at 31 March 2010.
