When we released stage 1 of free5GC (v1.0), we kept the S1AP interface to 4G eNB. We tested free5GC with some commercial eNBs successfully, including:
- GemTek WLTGFC-101 eNB, 3GPP Rel-9 compliance
- D-Link DWR-1012, 3GPP Rel-12 compliance
- WNC OSQ4G-01E2 eNB, 3GPP Rel-13 compliance
Our stage 2 (v2.0) and stage 3 (v3.0) implementations of free5GC follow the 3GPP R15 standalone (SA) standards. Because we cannot get any commercial 5G SA gNBs, so far we only tested free5GC with Spirent Landslide which is an 5G emulator. Some local companies in Taiwan will provide us real 5G SA gNBs. As soon as we get them, we will test them, which will be around Q4 this year. If you can provide us commercial 5G SA gNBs, we will be happy to test them too.
