Additional technical information
- Dimensions
- 384 × 85 × 417 mm (W × D × H) with solar shield, handle and feet; 374 × 80 × 320 mm without
- Weight
- Less than 10 kg including handle
- Bandwidth
- Instantaneous bandwidth up to 40 MHz
- Capacity
- WCDMA: 4 carriers; LTE FDD: 1 × 20 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 A2/A3 enclosure; may mount behind a standard RRU so both appear as one unit
- Modules
- Exchangeable SFP transceiver modules on two CPRI ports
- Functional role
- Receive-only two-branch radio adjunct used with an RRU to add four-way receive diversity
- Architecture
- Standalone or behind-RRU receive-diversity unit with two uplink RX branches, no downlink TX branch, cascading optical link and power feed to the associated RRU
- Subtype
- 0TX/2RX RRUS A2 diversity radio unit
- Details
- Normal operating temperature -40 to +55 °C; cold start at -40 °C; supports ALD/RET depending on software application
- Connection notes
- DU/Baseband via CPRI
