Consumption of video is driving exponential increases in mobile bandwidth demand. ACG Research projects most likely peak period bandwidth requirements to increase at 52 percent compound annual growth rate through 2018.

We use the forecast to model engineered backhaul capacity requirements for a 1,200 square kilometer metro area with a population of 2.5 million. This case study finds that the cell site backhaul bandwidth requirement will range between 0.4 Gbps and 2.5 Gbps in 2018. The odds favor the high end of this range. 10 Gbps Ethernet links in the access network and 10 Gbps rings will be needed to meet the demand requirement, support growth, and maximize load sharing. Agile network architectures will reduce the cost of supporting the expected rapid and volatile increases in mobile bandwidth demand.
