How blueprints unlock the potential of 5G networks

This describes the SCF roadmap for a series of technical and deployment blueprints that will provide common reference designs and deployment processes that reduce the time, cost and risk of developing a small cell network. While based on standard specifications, the blueprints will be specific to certain roll-out scenarios that are not currently addressed by the frameworks of other organizations. The first blueprints will focus on private networks.
