Additional technical information
- Dimensions
- 2018 Uen H: 586 × 291 × 162 mm without solar shield/handle; 690 × 306 × 178 mm with. 2016 Rev B data sheet gives 586 × 281 × 162 mm without; revision difference retained
- Weight
- 23 kg without solar shield/handle; 24 kg with solar shield/handle
- Bandwidth
- B3: IBW 40 MHz; operational bandwidth 40 MHz; conditions: [46] 1.4 MHz LTE, 3 MHz LTE and GSM carriers within 20 MHz. | [7] Operational bandwidth is the actual bandwidth allocated for carriers.
- Capacity
- GSM 1–8 carriers; LTE/MI 1–3 carriers; mixed GSM+LTE 2–11 carriers
- Synchronization
- Traffic and timing signals over optical interfaces 1 and 2 between RRUS 32 and the main unit
- Chassis
- Warranty-sealed, outdoor IP55 RRUS 32 enclosure with solar shield/handle; optional external PSU/DC adapter
- Modules
- Integrated TRX, PA, Filter Unit and DC/ALD/external-alarm surge protection; 2 exchangeable optical SFP modules; optional PSU/DC adapter
- Functional role
- Near-antenna multi-standard remote radio extending an RBS main unit over optical fronthaul in star/cascade topology
- Architecture
- Four-branch optical-fronthaul RRU: TRX performs A/D-D-A conversion, filtering, gain/delay adjustment, predistortion, RF modulation/demodulation and optical termination; PA and Filter Unit form the RF chain
- Subtype
- 4T4R RRUS 32 multi-standard remote radio unit
