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.



S-RU and S-DU test support

S-RU and S-DU

5G nFAPI [SCF225] adds a network transport wrapper around the 5G FAPI PHY API [SCF222] to create the split 6 interface between S-RU and S-DU small cell network units which SCF describes as Open6. Although a companion to SCF’s FAPI suite, this paper is not a specification but considers how to test the disaggregated units S-RU and S-DU of the RAN.
