Africell Sierra Leone is a mobile network operator in West Africa with over 4 million subscribers who had just launched 4G in 2018 on their radio access network. This launch caused capacity constraints on the transport layer of their network.
Case Study: Vodafone Fiji Successfully Deploys LOS MIMO Link Using WTM 4000 Solution
By Stuart Little, Director of International Product Line Marketing
Vodafone Fiji needed a solution to provide over 2 Gbps of capacity over a distance of more than 6.5 kilometers, but there was only one problem: lack of frequency spectrum. Vodafone only had a single 80 MHz channel allocation in the 11 GHz band. Aviat was able to design a link using their WTM 4000 all-outdoor radio platform, employing Line-of-Sight (LOS) MIMO to quadruple the efficiency of the single available frequency channel.
