This document summarizes research on trends in mobile backhaul networks in Russia and globally. It finds that mobile backhaul networks are becoming the bottleneck as networks transition to high-speed technologies like 4G/LTE. This is driving operators to upgrade their transport networks. In Russia, mobile data traffic increased 123% in 2012 and is forecast to grow over 12 times by 2016. Major operators are increasingly connecting base stations with fiber optic and high-speed microwave lines. While fiber optic is most preferred for 4G, microwave still dominates the global mobile backhaul market, expected to comprise 56% of revenues by 2017 despite growing fiber usage. Russian operators have been steadily increasing investments in backhaul networks, projected to reach $7 billion annually
