The Wi-Fi Alliance, a global certification network, unveiled a low-power and long-distance Wi-Fi connection dubbed Wi-Fi HaLow (pronounced ‘halo’). This was designed specifically for low-power devices which will power our smart cities and homes. HaLow is an extension on the next Wi-Fi standard, IEEE 802.11ah, which will be released in a few years. It will operate at 900 MHz which will allow the signal to easily penetrate walls and the range to be much larger than current Wi-Fi which operate at 2.4GHz or 5GHz.
The trade-off for having extended range and being able to connect low-power devices to Wi-Fi will be slower speeds. This is designed for the small sensors and other devices which will make up the Internet of Things in the future.
