For PN KRC161109/1.
Downlink frequency: PN KRC161109/1; 2110–2170 MHz
For PN KRC161109/1.
RF output power: PN KRC161109/1; 20 W nominal; 23 W maximum; with two carriers, 10 W nominal per carrier
For PN KRC161109/1.
Capacity: 1 carrier at 20 W nominal or 2 carriers at 10 W nominal
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: Complete outdoor RRU22 xx20 enclosure containing all radio functionality; passive cooling; optional sunshield/mounting brackets
Modules: Filter Unit; TRX Board; Power Amplifier
Functional role: PN KRC161109/1; WCDMA RBS remote radio unit located close to the antenna
For PN KRC161109/1.
Architecture: Radio Equipment (RE) side of a classic CPRI fronthaul; CPRI optical link to Main Unit; two antenna jumpers; RET; 2RX (receive diversity); clock and time are recovered from the REC/Baseband at the CPRI slave interface
Subtype: PN KRC161109/1; RRU22 remote radio unit
For PN KRC161109/1.
Details: Located near the antenna; contains radio-specific hardware while control/baseband/switching/Iub remain in the Main Unit; passive fanless cooling; RET and RX-diversity antenna connections
