Regulators have been encouraging infrastructure sharing in the countries where the private sector leads the effort. Where the economic efficiencies of aggregating backbone have been considered, LDCs like Burundi have created a Special Purpose Vehicle (SPV) where operators create an entity to serve as the wholesale infrastructure provider (Box 2-7). It is a joint venture between the Government of Burundi and four telecom operators (Ucom Burundi, Africell Tempo, Onatel) and an Internet Service Provider (CBINET).
