Overview
The AWT100-AP/WFH Series is a Wi-Fi data conversion module compliant with the IEEE 802.11ah (Wi-Fi HaLow) standard. It operates in both AP (Access Point) and STA (Station) modes, enabling point-to-point or point-to-multipoint wireless data transmission. With sub-1GHz operating frequencies (902-928MHz for EU version, 859-894MHz for NA version), it offers significantly longer transmission distances compared to traditional 2.4GHz Wi-Fi. The module features a physical throughput of 150kbps to 3.5Mbps, supporting applications from low-speed sensors to high-speed image data transmission. Ideal for wireless meter reading, building automation, security systems, and power load monitoring.

FAQ
In AP mode, the module creates a wireless network for other devices to connect. In STA mode, it connects to an existing AP. The two modes enable point-to-point or point-to-multipoint networks.
Long press the button to toggle between AP and STA modes. Short press to enter or leave auto-provisioning mode. LED indicators show the current mode and status.
Wi-Fi HaLow operates in sub-1GHz frequencies, offering longer transmission distances and better wall penetration, making it ideal for large industrial sites and buildings.
While the exact distance depends on environmental factors, Wi-Fi HaLow typically achieves kilometer-level ranges, significantly exceeding 2.4GHz WiFi.
Yes. One device in AP mode can connect to multiple devices in STA mode, forming a point-to-multipoint network. Relay and roaming features further extend coverage.
