Dimensions
454.5 × 342.5 × 240 mm (H × W × D), without fan
Weight
31.0 kg
Bandwidth
B20: IBW 30 MHz; operational bandwidth 30 MHz; B28B: IBW 30 MHz; B8: IBW 35 MHz; operational bandwidth 35 MHz; conditions: [47] 1.4 or 3 MHz LTE carriers within 25 MHz. All other carriers within 40 MHz IBW when using 1.4 or 3 MHz LTE carriers. | [7] Operational bandwidth is the actual bandwidth allocated for 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
