The Wi-Fi Alliance says Wi-Fi HaLow has almost twice the range of the Wi-Fi we use now and will provide more reliable, stronger connectivity in environments where today's Wi-Fi has problems (like getting signals through walls and floors).
"Wi-Fi HaLow is well suited to meet the unique needs of the smart home, smart city, and industrial markets because of its ability to operate using very low power, penetrate through walls, and operate at significantly longer ranges than Wi-Fi today," according to Alliance President and CEO Edward Figueroa. "Wi-Fi HaLow expands the unmatched versatility of Wi-Fi to enable applications from small, battery-operated wearable devices to large-scale industrial facility deployments -- and everything in between."
Specifically, Wi-Fi HaLow is intended for devices that use IEEE 802.11 ah technology. It operates in frequency bands of less than one gigahertz, which the Alliance says is why it uses less power and can function over a longer range. A particular point of interest is that Wi-Fi HaLow is capable of connecting thousands of devices to a single access point.
No, Wi-Fi HaLow won't replace today's Wi-Fi
For the record, the Wi-Fi Alliance intent is that WiFi HaLow will operate in conjunction with existing Wi-Fi. In a statement the Alliance explained "Wi-Fi HaLow complements existing Wi-Fi technologies and expands Wi-Fi Alliance's overall portfolio with a low power solution that will enable Wi-Fi to maintain its critical role in the IoT."
