Nokia Siemens Networks (NSN) revealed this week that it has won a five-year contract from Vodacom Tanzania to modernise the cellco’s mobile networks in the country. Under the terms of the contract, the Finnish-German vendor will implement a single radio access network (RAN) platform in the country to replace Vodacom’s existing GSM and 3G base transceiver stations (BTS). The multi-technology platform is able to run GSM, HSPA and Long Term Evolution (LTE), and can be defined to roll out a particular technology with a simple software update, it said. Additionally, NSN will provide Vodacom with its so-called ‘liquid radio-based self-organising network (SON)’ for the RAN and core network as well as its NetAct powered network management solutions. Further, the vendor is also deploying additional GSM and 3G BTS to expand coverage, and will deploy its software features to increase network capacity and efficiency.
