Additional technical information
- Dimensions
- Without solar shield/handle: 406 × 416 × 128 mm (H x W x D); with solar shield/handle: 500 × 431 × 182 mm
- Weight
- 21.6 kg without solar shield/handle
- Bandwidth
- B38: IBW 20 MHz; operational bandwidth 20 MHz; conditions: [7] Operational bandwidth is the actual bandwidth allocated for carriers.
- Capacity
- One LTE carrier, up to 20 MHz TDD
- 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
