Overview
AHMC7292S is the world’s first IEEE802.11ah module
The AHMC7292S IEEE802.11ah module series allows building of long-range, ultra-
low power WiFi networks in Sub 1 GHz license-exempt bands. WiFi HaLow™ enables
connectivity for many applications, including sensors and IoT devices.
The AHMC7292S supports for standalone mode, High data throughput and complete
SDK, getting started with this new WiFi standard will be straightforward.
Standalone Mode
In this mode, the target device doesn’t need external drivers. It will be up
and running by itself while powered on. Since it’s a self-running device, it
requires built-in firmware to define its routines and behaviours.
Other devices can talk to this device through a UART interface, send AT
commands and receive data with it.
