Additional technical information
- Dimensions
- 518 × 470 × 190 mm (H × W × D) with solar shield, handle and feet; 418 × 458 × 159 mm without solar shield, handle or feet
- Weight
- B1/B2/B4/B7: 22.4 kg; B3/B3A/B5/B8: 26.3 kg; B28A: 23.7 kg; B28B: 24.3 kg
- Bandwidth
- B1: IBW 40 MHz; operational bandwidth 20 MHz; B2: IBW 40 MHz; operational bandwidth 25 MHz; B28A: IBW 20 MHz; B28B: IBW 25 MHz; B3: IBW 40 MHz; B3A: IBW 40 MHz; B4: IBW 40 MHz; B5: IBW 25 MHz; B7: IBW 40 MHz; B8: IBW 35 MHz; B8A: IBW 26 MHz; conditions: [7] Operational bandwidth is the actual bandwidth allocated for carriers. | [10] Up to four CDMA or GSM carriers. Maximum 20 MHz available for LTE and WCDMA carriers.
- Capacity
- WCDMA: 1–4 carriers; LTE: 1–2 carriers; GSM: 1–8 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
- Chassis
- Standalone sealed outdoor RRUS enclosure with solar shield and connection panel; optional rear-mounted PSU and vandal protection
- Modules
- Integrated TRX, 2 power amplifiers, Filter Unit, DC SPD, ALD/RET SPD and external-alarm SPD; 2 optical SFP modules; optional external PSU and RF-monitoring-port assembly
- Functional role
- Ericsson RF radio product
- Architecture
- Radio Equipment (RE) side of a classic CPRI fronthaul; 2 data port(s); cascading support: yes; different line rates on different ports: yes; CPRI line rates: 1.2, 2.5 Gbps; conditions: [14] RRUS 12 B7 does not support different line rates on different ports.; 2T2R; clock and time are recovered from the REC/Baseband at the CPRI slave interface
- Subtype
- Ericsson RF Radio Equipment using classic CPRI fronthaul; 2T2R
- Details
