RF Testing for IoT Devices: Preparation & Standards to Consider

IoT devices often integrate multiple protocols (BLE, Wi-Fi, LoRa, NB-IoT). RF testing ensures the device operates in the correct frequency band, limits power, and does not cause interference.
1. Key Measurements
- TX Power & Frequency Conformance: confirms the transmit power and frequency band.
- Receiver Sensitivity: receiver sensitivity to ensure connection range.
- Spurious Emissions & Harmonics: out-of-channel emissions.
- Throughput & Coexistence (Wi-Fi/BLE): test performance when used simultaneously.
2. Reference Standards
- EN 300 328 (Wi-Fi), EN 303 446/EN 300 220 (SRD), FCC Part 15, related QCVN.
- Some markets also require SAR or frequency certification.
3. Prepare samples & data
- Catalog, firmwares, antenna spec, test firmware to keep TX/RX status fixed.
- Describe test scenarios (modulation, data rate, channel).
Conclusion: Accurate RF testing helps avoid errors at customs and increases the rate of passing certification. VhanaVN supports RF testing, spectrum analysis and supports completing certification documents. Send model & request RF test — Hotline 035 328 9097
