Swedish technology provider Ericsson has been contracted by Angolan cellco Unitel to develop its 4G Long Term Evolution (LTE) mobile broadband network, which was launched commercially by the two partners in December 2012. Ericsson confirmed on Friday that, following Unitel’s LTE launch the parties entered into an agreement wherein the Scandinavian firm would undertake the design and implementation of the LTE network, reports South African site EngineeringNews. The agreement included the integration of LTE functionality into existing provisioning and charging systems and an upgrade of the core network to a triple-access (2G/3G/4G) evolved packet core. ‘The new LTE network will facilitate Unitel’s continued delivery of superior connectivity, services and capabilities to their customers,’ said Ericsson’s head of sub-Saharan Africa, Lars Linden. In December Unitel launched LTE services in the Angolan capital Luanda, and intends to expand coverage to other provinces. Ericsson’s commitments include the installation of new LTE cell sites and the provision of its Home Subscriber Servers (HSS) platform to manage user data.
