Wi-Fi HaLow Module

Product Features

Overview

This module is designed based on the FGH100M, a long-range, low-power Wi-Fi HaLow module compliant with the IEEE 802.11ah standard. It supports Sub-1 GHz band communication, with available frequency bands varying by region. Currently, 868 MHz and 915 MHz options are available. It is suitable for Internet of Things (IoT) and smart device scenarios.
