Additional technical information
- Weight
- 20 kg
- Dimensions
- 636 × 383 × 169 mm (H × W × D) with solar shield; 600 × 350 × 112 mm without solar shield
- Bandwidth
- B3: IBW 20 MHz; operational bandwidth 20 MHz; conditions: [9] For GSM: The IBW is dependent on modulation techniques for RUS 01 and RRUS 01. | [83] For GSM: The instantaneous bandwidth is limited to 15 MHz when the output power is larger than 60 W. | [7] Operational bandwidth is the actual bandwidth allocated for carriers.
- Capacity
- 1–4 carriers, subject to license
- Synchronization
- Traffic and timing signals over optical interfaces 1 and 2 between RRUS 01 and the main unit
- Chassis
- Convection-cooled RRUS 01 outdoor enclosure with mandatory solar shield and installation cover; optional rear PSU/ACCU
- Modules
- Integrated TRX, one PA, Filter Unit and DC/ALD/external-alarm surge protection; approved optical SFP modules; optional rear PSU/ACCU and RF monitoring port
- Functional role
- Near-antenna remote radio unit extending an RBS main unit over optical fronthaul in star or cascade topology
- Architecture
- Optical-fronthaul RRUS with TRX performing A/D-D/A conversion, filtering, gain/delay adjustment, predistortion and RF modulation/demodulation; one PA feeds the Filter Unit
- Subtype
- 1TX/2RX RRUS 01 multi-standard FDD remote radio unit
- Details
- Normal environment -40 to +55 °C, 5–100% RH; no acoustic noise; maximum front wind load 480 N at 50 m/s. At 80 W high load, the upper ambient limit is +45 °C.
- Connection notes
- DU/Baseband via CPRI
