MTN Nigeria, the country’s largest mobile operator by subscribers, plans to invest USD1.3 billion in 2012, part of which is being spent on a wireless network upgrade and modernisation project. Local newspaper Daily Trust cites the company’s corporate services executive Wale Goodluck as saying that MTN is using the funds to upgrade and replace key network components to enhance capacity and improve service quality. Ericsson, Huawei Technologies and ZTE have been hired as technical partners for the project, which will be carried out at night to reduce the effect on the quality of the operator’s service. TeleGeography’s GlobalComms Database states that South Africa-based MTN Nigeria had a total of 42.9 million wireless subscribers at 31 March 2012, corresponding to a 43.5% share of Nigeria’s total 98.5 million cellular users. Last month MTN, UAE-based Etisalat, Airtel (owned by Indian telco Bharti Airtel) and Globacom were together fined NGN1.17 billion (USD7.3 million) for failing to meet quality of service standards.
