5G FAPI specs updated with richer 3GPP feature set

5G FAPI suite with richer 3GPP feature set to underpin supply chain diversification

SCF has updated the suite of 5G FAPI specifications which underpin the high-performance low-cost components integral to 5G mobile base stations, whether small cell or macro. This update demonstrates the ongoing commitment of the ecosystem to continually improve the standard, adding new features and maintaining existing ones.

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.
