Additional technical information
Bandwidth
B1: IBW 60 MHz; operational bandwidth 60 MHz; B3: IBW 75 MHz; operational bandwidth 75 MHz; conditions: [29] 40 MHz IBW per RF port for NB-IoT standalone. | [7] Operational bandwidth is the actual bandwidth allocated for carriers. | [73] 20 MHz IBW per RF port for GSM carrier.
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
Separate outdoor enclosure Radio 2260 with rail mounting or ERS-bracket
Modules
Pluggable optical modules SFP+; optional external fan Fan 10
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, 10.1 Gbps; 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
