HaLow is the Wi-Fi Alliance branding for IEEE 802.11ah. WiFi. 802.11ah operates in sub-1 GHz bands to provide longer range at lower power than other WiFi solutions. HaLow may therefore be considered a lowpower wide-area (LPWA) networking technology. HaLow typically operates in the unlicensed 900 MHz band, but also operates in 700 MHz and 800 MHz bands in some countries.
