Phase3 Telecom of Nigeria has expanded its high-capacity IP-based network to Lagos, Kano, Abuja and Port Harcourt, according to local newspaper Vanguard. The company recently embarked on the expansion and upgrade of its national aerial backbone, with the aim of lowering tariffs and termination charges, whilst improving public access to international IP networks. Phase3 has already completed work in a number of cities including Oshogbo, Asaba, Ilorin, Akure and Abeokuta. According to TeleGeography’s GlobalComms database, the company announced in June 2008 it had invested over USD100 million in its fibre-optic backbone, with a further USD200 million to be spent expanding the network across the country. Earlier this year the company partnered with Alheri Engineering, a member of the Dangote Group, to build a ‘one network’ fibre backbone traversing major towns and cities in the country.
