Nigeria’s largest mobile operator by subscribers, MTN Nigeria, has confirmed it plans to invest USD1 billion in its wireless network during 2012 to improve the quality of services, Bloomberg reports, citing MTN spokesman Akinwale Goodluck. ‘The investment will relieve congestion and improve the quality of the network,’ Goodluck said, adding that the funds will be spent on 2G and 3G technologies, MTN’s core network and power generators to run transmission stations. The announcement follows demands for the country’s mobile operators to improve the quality of services made by telecoms regulator the Nigerian Communications Commission (NCC) last year. In October 2011 the watchdog warned the three largest mobile operators by subscribers – MTN, Globacom and Airtel Nigeria – that they would face fines and would also be prevented from signing up new subscribers if they failed to improve mobile service quality. According to TeleGeography’s GlobalComms Database, MTN held a 45.4% share of Nigeria’s mobile market at the end of September 2011, with a total subscriber base of 41.107 million, ahead of second-placed Globacom (21.6%) and Airtel Nigeria, which is a unit of Indian group Bharti Airtel, (17.7%).
