What is a wireless module?

For IoT products, a wireless module helps devices connect, communicate, sense, or locate without building every RF design from scratch.

Different products need different modules:

- Wi-Fi for high-speed local connectivity
- BLE for low-power nearby interaction
- LoRa for long-range sensor networks
- UWB for precise indoor positioning
- Radar for privacy-friendly presence sensing
- Cellular IoT for wide-area monitoring

The right choice depends on the application scenario, power budget, communication range, data type, and product design.

Ai-Thinker provides different wireless and sensing modules for IoT product teams building smart home, industrial, outdoor, positioning, and connected device applications.
