Core Application Scenarios

• 5G Device Protocol Compliance — NSA/SA mode switching and handover testing (Based on signaling capabilities)

• mmWave Beamforming Validation — OTA testing with AoA measurement for FR2 devices (Based on OTA capabilities)

Leasing Scenario Technical Adaptation

• Compact Lab Deployment — Single-unit solution replaces multiple test instruments (Reduces bench space 60%)

• Future-Proof Investment — Software-upgradable for 3GPP Release 16+ features (Based on platform description)

Integrated Signaling Architecture

Features "Multi-Protocol Stack Processor + Unified RF Front-End" design: Single platform runs 5G NR/LTE/eMTC protocol stacks simultaneously (Source: Input description). Integrated fading simulator emulates multi-path environments for mobility testing. Modular RF architecture supports baseband unit + RRH configuration for mmWave OTA testing. AoA measurement capability uses phased array calibration to validate beam-steering accuracy (±1° resolution).

5G mmWave Device Validation Workflow

1. Connection: DUT in OTA chamber, UXM baseband unit connected to mmWave RRH

2. Configuration: Establish SA 5G call at 28GHz, enable internal fading (urban micro scenario)

3. Testing:
   - Measure beam-switching latency during mobility
   - Verify FR2 EVM < 3% at peak data rates
   - Validate AoA accuracy during beam tracking

4. Analysis: Generate protocol/RF compliance report, flag beam failure events

mmWave Test Boundary

Maximum path loss for reliable mmWave testing: 140dB (Based on typical RRH specifications). Mitigation: ① Use chamber with <1m test distance; ② For large chambers, add RF amplification (requires external hardware calibration).
