Additional technical information

Dimensions: 2016 Rev B: 586 × 281 × 162 mm (H × W × D) without solar shield; 690 × 306 × 178 mm with solar shield
Weight: 24 kg
Bandwidth: Up to 70 MHz instantaneous bandwidth; up to 60 MHz LTE carrier capacity
Capacity: LTE capacity up to 60 MHz; IBW up to 70 MHz
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 outdoor IP55 RRUS 72 enclosure with solar shield
Modules: 2 exchangeable SFP modules for CPRI; optional PSU AC 08
Functional role: Near-antenna multi-standard remote radio extending an RBS main unit over optical fronthaul in star/cascade topology
Architecture: Four-branch near-antenna remote radio linked to the RBS main unit by optical fiber in star or cascade topology
Subtype: 4T4R RRUS 72 remote radio unit
Details: Normal outdoor operation -40 to +55 °C; cold start at -40 °C
Connection notes: DU/Baseband via CPRI
