简要描述：
RRU 5512T (02312YMW) uy the Huawei RRU5512T (02312YMW) — a tri-band 4T4R remote radio unit supporting 700 MHz (Band 28), 800 MHz (Band 20), and 900 MHz (Band 8) for GSM, UMTS, LTE FDD, NB-IoT, and 5G NR FDD networks.Delivers up to 4 × 80 W output power, dual CPRI front-haul, and IP65 outdoor protection, ideal for macro base stations, low-frequency 5G coverage, and multi-RAT co-deployment.
The Huawei RRU5512T is a tri-band low-frequency remote radio unit (RRU) designed for macro base station deployments.
It supports 700 MHz (Band 28 / n28), 800 MHz (Band 20 / n20), and 900 MHz (Band 8 / n8) simultaneously.
The unit enables multi-RAT operation across GSM, UMTS, LTE FDD, NB-IoT (SUL), and 5G NR FDD, providing wide-area coverage and deep indoor penetration.
It is commonly used in 4G and 5G FDD co-deployment and legacy network modernization scenarios.
| Parameter | Specification |
|---|---|
| Supported Bands | 700 MHz (B28/n28), 800 MHz (B20/n20), 900 MHz (B8/n8) |
| Duplex Mode | FDD |
| Supported RATs | GSM / UMTS / LTE FDD / NB-IoT (SUL) / NR FDD |
| MIMO Configuration | 4T4R per band |
| Instantaneous Bandwidth (IBW) | 700 MHz: 30 MHz; 800 MHz: 30 MHz; 900 MHz: 35 MHz |
| TX Frequency | B28: 758–788 MHz / B20: 791–821 MHz / B8: 925–960 MHz |
| RX Frequency | B28: 703–733 MHz / B20: 832–862 MHz / B8: 880–915 MHz |
The RRU supports single, dual, or triple-band concurrent operation, with flexible RAT combinations (e.g., GSM/LTE/NR FDD).
Built-in PIM suppression with a maximum cancellation gain of 15 dB ensures stable performance in shared-antenna scenarios.
| Band | Max Output Power | MIMO | Typical Carrier Configuration |
|---|---|---|---|
| 700 / 800 / 900 MHz | 4 × 60 W (per single band) | 4T4R | LTE: up to 2CC; NR FDD: up to 2CC |
| Dual-band (e.g., 700+900) | 4 × 80 W total | 4T4R shared | LTE: up to 4CC; NR: up to 4CC |
| Tri-band (700+800+900) | 4 × 80 W total | 4T4R shared | LTE/NR: up to 6CC total |
Total output power across combined bands must not exceed 80 W per transmit path.
Front-haul Interface: 2 × CPRI ports
Supported Rates: 2.5G / 4.9G / 9.8G / 10.1G / 24.3Gbit/s
Max Daisy Chain:
GSM / UMTS: up to 6 units, ≤40 km
LTE FDD: up to 4 units, ≤40 km
NR FDD / NB-IoT: up to 4 units, ≤20 km
Power Supply: −48 V DC (operating range: −36 to −57 V)
Typical Power Consumption: ≈ 670 W at 25 °C, 50% load
Power Management: Intelligent dynamic PA biasing for energy saving
| Parameter | Specification |
|---|---|
| Dimensions (H × W × D) | 480 × 356 × 140 mm |
| Weight | Approx. 25 kg (excluding mount kit) |

| Relative Humidity | 5% – 100% RH (1–30 g/m³ absolute) |
| Altitude | ≤ 4000 m (power derating above 2000 m) |
| Ingress Protection | IP65 (outdoor use) |
| Lightning Protection | DC port surge withstand: 20 kA (8/20 μs waveform) |
| Compliance | ETSI EN 300 019 (Environmental), GR-63 (Seismic Zone 4), IEC 62305-1 / ITU-T K.35 / K.56 / K.97 (Lightning) |
RF Ports: 4 TX/RX ports (mapped as A/B/C/D per frequency band)
Optical Ports: 2 × CPRI SFP interfaces
Alarm & Sync: SIN / SOUT / EAC ports (for synchronization and external alarms)
Best Practice: Use factory-calibrated jumpers (≤6 m) and avoid passive combiners to minimize PIM.
Tri-band low-frequency site integration: 700/800/900 MHz co-sited LTE + 5G deployment for deep coverage.
Legacy modernization: Upgrade GSM/UMTS macro sites to support NB-IoT and NR FDD.
Power-limited sites: Consolidate multiple RRUs into one compact tri-band module to reduce energy and space usage.
