The Evolution of Mobile Fronthaul to Support RAN Architecture Migration to 5G

It is widely understood that there is rapid bandwidth growth in wireless networks and there is plenty of literature detailing the likely path that radio architecture in the RAN will take to accommodate this growth. Technologies like coordinated multi-point (CoMP), carrier aggregation, and more complex and dynamic multipleinput multiple-output (MIMO) schemes will allow radio access networks to scale to accommodate immense amounts of bandwidth per handset as rollouts of 4G and 4.5 Long Term Evolution Advanced (LTE-A) networks are completed and operators ultimately move to 5G.
