Additional technical information

Dimensions: 410 × 334 × 176 mm (H × W × D) without sunshield; 470 × 365 × 257 mm with sunshield and mounting brackets; 24 L without sunshield
Weight: 19 kg without sunshield; 24 kg with sunshield
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: WCDMA RBS remote radio unit located close to the antenna
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: RRU22 remote radio unit
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
