Overview
The 8854 is a 4T4R Remote Radio Unit (RRU) developed by ZTE. Designedbased on the RRU unified platform, the 8854 supports GSM/UMTS/LTE singlemode or multi-mode. This unit can provide S9000, S1800, S2100, and S2600 LTE frequencies.
| Parameter | Value / Notes |
|---|---|
| General / Functionality | It is a 4T4R RRU (4 transmit & 4 receive chains) |
| Operating Bands / Variant | “S2100” indicates the 2100 MHz band variant. |
| Supported Modes / Multi-mode | Supports GSM / UMTS / LTE in single- or multi-mode, depending on configuration |
| Bandwidth / LTE Bandwidths | 1.4, 3, 5, 10, 15, 20 MHz supported |
| Total Output Power | 4 × 40 W (i.e. up to 40 W per TX chain) |
| Receiver Sensitivity | Examples for LTE (single antenna / dual / four antennas) in relevant bands: – For LTE B3 / B7: –106.4 dBm / –109.2 dBm / –112 dBm – For GSM B3: –113.5 dBm (single) / –115.5 dBm (dual) |
| Power Supply / Input | DC: –48 V (acceptable range somewhere in –37 V to –60 V) Integrated DC lightning protection (20 kA) |
| Power Consumption | For LTE single mode: ~290 W (average) and ~515 W (peak) for S1800/S2100 variants In dual-mode configurations (G/L, U/L), somewhat higher consumption (e.g. 345 W average, 525 W peak) for S2100 variant in UMTS/LTE dual mode |
| Physical / Mechanical | Dimensions: 415 × 296 × 104 mm (HxWxD) Weight: ~15 kg (for many R8854 variants) Volume: 12 L (typical) |
| Interfaces / Ports | Antenna interfaces: 4 ports (ANT1–ANT4), TX/RX (50 Ω DIN / NSBT) CPRI / optical interfaces: 2 × LC optical SFP ports for connection to BBU or cascading Power input: 2-pin custom connector AISG / MON (monitoring) and O&M Ethernet (LMT) via DB15 connector Grounding: protective ground terminal (e.g. 16 mm² terminal) |
| Environmental / Operating Conditions | Operating temperature: –40 °C to +55 °C Relative humidity: 5% to 100% (condensing) Dust / water protection: IP65 rating Ground / earth requirements: ≤5 Ω earth resistance typical; in low thunderstorm regions less than 10 Ω acceptable |
| Reliability / MTBF / Availability | MTBF ≥ 499,000 hours MTTR ≈ 1 hour Availability: ≥ 99.999800% |
