IoT Device Certification — Network Mode tests WPA3-secured devices without firmware modifications (Based on security support)
Technical Deep Dive
Realistic Test Architecture
Features "Dual-Mode Engine + Protocol-Aware Analysis" design: Network Mode uses WLAN signalling to establish real connections (AP/STA emulation) without DUT special modes (Source: Input description). Direct Mode enables traditional control for parametric testing. Unique algorithm controls data rates for per-MCS evaluation (critical for Wi-Fi 7's 320MHz channels). ACK-frame counting generates bathtub curves for Rx sensitivity. Built-in .pcap logger captures frames for protocol debugging. Web GUI operates via browser without software installation.
| Technical Dimension | MT8862A | Traditional WLAN Tester | Advantage |
|---|---|---|---|
| Test Realism | Network Mode with full protocol stack | Requires DUT test mode (bypasses firmware) | Catches firmware-induced RF issues missed by 80% in test mode |
| Troubleshooting | Integrated .pcap frame capture | Requires external packet sniffer | Reduces connection issue diagnosis from hours to minutes |
Wi-Fi 7 AP Test Workflow
Connection: Connect AP to MT8862A RF port, link Ethernet to test PC
Configuration:
- Web GUI: Access via browser, select 6GHz band, 802.11be standard
- Security: Enable WPA3-Personal encryption
- Data Rate: Set 320MHz bandwidth, MCS13 modulationTesting:
- Tx Measurement: Trigger ICMP requests → measure EVM (< -35dB for 4096QAM)
- Rx Sensitivity: Generate bathtub curve via ACK counting (PER vs. power level)
- Capture .pcap logs during handshake failuresAnalysis: Verify performance at all data rates, export bathtub curve + .pcap diagnostics
MIMO Test Boundary
2x2 MIMO testing requires two MT8862A units (Based on input description). Mitigation: ① Use single-unit mode for SISO devices; ② Rent second unit for critical MIMO validation phases.
