The Baseband 6648 is a 1U standalone baseband unit for Ericsson Radio System, built for NR and LTE. Every one of its twelve radio ports carries both CPRI and eCPRI, and it is the unit that supplies the 24.3 Gbit/s CPRI and 25 Gbit/s eCPRI rates the newest radios need. It is not a general-purpose replacement for an older baseband — it drops GSM and WCDMA entirely.
