Additional technical information
Dimensions
1439 × 327 × 220 mm (H × W × D)
Weight
48 kg
Bandwidth
B4: IBW 45 MHz; operational bandwidth 40 MHz; conditions: [95] 1.4 and 3 MHz LTE carriers within 20 MHz IBW. | [7] Operational bandwidth is the actual bandwidth allocated for carriers.
Capacity
AAS beam metric — TX: 4; RX: 4
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
Integrated outdoor antenna and radio unit housing with front radome, rear fan tray and wall brackets/pole
Modules
Integrated RRUS 32A B4 (KRC118050/1), active antenna B4, passive antenna B2, integrated optics SFP; separately replaceable fan
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: 2.5, 4.9, 9.8 Gbps; 4T4R; clock and time are recovered from the REC/Baseband at the CPRI slave interface
Subtype
Ericsson RF Radio Equipment using classic CPRI fronthaul; 4T4R
