Additional technical information

Bandwidth: B1B: 55 MHz IBW / 55 MHz operational, with NB-IoT standalone limited to 20 MHz IBW per RF port; B3A: 50/50 MHz, with GSM and NB-IoT standalone limited to 20 MHz IBW per RF port
Synchronization: When operated over its documented classic CPRI interface: CPRI slave synchronization; the radio recovers the incoming CPRI bit clock for radio/link transmission and receives time information from the REC/Baseband
Functional role: Dual-band RF radio unit for external antennas, connected by classic CPRI
Architecture: Radio Equipment with four TX/RX antenna branches and two CPRI data ports; cascading and independent CPRI line rates are supported
Subtype: 4T4R common-port B1B+B3A dual-band Radio 4481
Connection notes: DU/Baseband via CPRI
