This report spotlights telcos’ strategies regarding backhauling and fixed mobile convergence, how the transport network is evolving within the migration to all-IP and which choices telcos take to meet the increasing demand of bandwidth. The study analyses the evolution of backhaul networks, its investment control and the necessary implementation with the legacy infrastructure.

Key questions

How high are the Capex and Opex related to the mobile backhaul infrastructure? What are the technologies used and which one can be a cost-effective alternative?
What are the stakes for operators? How can they improve their mobile backhaul infrastructure ?
What are the upcoming trends for backhhaul upgrade? How are the major MNOs deploying their backhaul strategy?
Is optical fibre the unique answer to rising mobile data traffic due to LTE deployment?
