The connected-device future demands for an efficient power saving and easy to handle radio technology operating outside of the crowded 2.4 GHz band. The WiFi alliance, the organization that dictates and develops Wi-Fi standards, has announced a new member of the IEEE 802.11 specifications‘ family, IEEE 802.11ah called WiFi HaLow™.
WiFi HaLow is operating in the 900 MHz and primarely designated for low data payloads as required for the home/building automation, Internet-enabled coffee-makers and wearables, i.e. the Internet of Things (IoT) and Machine-to-Machine communication (M2M).
Contrasting with existing technologies as Bluetooth®, ZigBee® and Z-Wave™, WiFi HaLow connects devices directly to the Internet, not just to another device.
HaLow operating in the 900 MHz band is doing a better job of penetrating walls, floors, and other obstacles in contrast to the 2.4 GHz band Bluetooth. Wi-Fi HaLow’s range is nearly twice that of today’s Wi-Fi, and will not only be capable of transmitting signals further, but also providing a more robust connection - of course with lower speed.
