Additional technical information
Bandwidth
B40A: IBW 40 MHz; operational bandwidth 40 MHz; conditions: [7] Operational bandwidth is the actual bandwidth allocated for carriers.
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
Self-contained, warranty-sealed RRUL 62 enclosure with natural-convection cooling
Modules
Optional external PSU AC 02; optional wall/pole mounting equipment; supported external antenna-line equipment includes TMA, RETU/RIU and ALD/RET control
Functional role
Remote Radio Unit LTE (RRUL) 62 for LTE TDD, connected to the main unit by optical fibre in star or cascaded configuration
Architecture
Remote LTE radio connected by optical fibre in star or cascade topology; two bidirectional TX/RX channels; supports TMA and remote antenna tilt through RIU/ALD/RET control; naturally convection cooled
Subtype
Two-channel bidirectional TX/RX LTE-TDD remote radio unit
Details
No acoustic noise; normal operation -40 to +55 °C; solar radiation ≤1120 W/m²; relative humidity 5–100%; absolute humidity 0.26–40 g/m³; maximum wind 50 m/s; natural-convection cooling
