Additional technical information
Bandwidth
B1: IBW 60 MHz; operational bandwidth 60 MHz; B3: IBW 75 MHz; operational bandwidth 75 MHz; conditions: [32] For Radio 4443 B1 B3: Maximum 320 W for both bands together. NB-IoT standalone: 20 MHz IBW | [7] Operational bandwidth is the actual bandwidth allocated for carriers. | [79] For Radio 4443 B1 B3 on band 3: Maximum 320 W for both bands together. GSM: 20 MHz per port. Supports Virtual IBW. LTE: Maximum 32 W for 1.4 and 3 MHz carriers.
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
