Small cell backhaul is crucial for connecting small cells to the core network, internet, and other services. It's needed to provide carrier-grade connectivity at a lower cost per bit, especially in urban outdoors where small cells are often deployed in hard-to-reach locations.

Existing broadband internet can be used for in-building small cell backhaul, but in urban outdoors, mobile operators face a greater challenge due to the difficulty of reaching near-street-level locations. A toolbox of different wireless and wired technologies will be needed to address various deployment scenarios.

The Small Cell Forum has published an industry consensus view on how different solution characteristics match with requirements. This view is essential for operators to choose the right backhaul solution for their specific needs.

Small cell networks require a radio access network (RAN) architecture, and recent trends in RAN architecture developments are driving the evolution of small cell networks. The trend towards disaggregation and split solutions is making the concept of a single small cell less relevant than a network of small cells.

A disaggregated, split small cell network consists of several radio units, one or more distributed units, and a centralized unit, providing the necessary coverage and capacity in an enterprise and/or a dense urban area. This architecture lends itself naturally to virtualization, especially of the centralized units.

The Small Cell Forum is developing open specifications for small cell networks, including data and control interfaces, as well as management solutions. This will enable quicker, cheaper small cell design, manufacture, and rollout for 5G and densified networks.
