Infrastructure sharing is one of the main trends in broadband infrastructure deployment. Indeveloping countries, particularly in sub-Saharan Africa, there is a trend for governments to backinfrastructure sharing projects as a way to reduce costs in network deployments, expand coverage,reduce the rural-urban digital divide, and accelerate broadband take-up.Traditional infrastructure sharing models, such as regulated access to the so-called “last-mile”network or site sharing agreements among mobile operators, have given way in recent times tonew designs. The mutualisation model, where a common facility is operated by all marketparticipants, and the cooperative model, where the telecommunication infrastructure is housed orjointly constructed with other linear infrastructures, are the two most popular designs.
