Wi-Fi HaLow outperforms LoRa / LoRaWan Gear in scenarios requiring higher bandwidth, lower latency, IP-native integration, and enhanced security. While LoRa is ideal for ultra-low-power, low-data applications like remote sensors, Wi-Fi HaLow is the superior choice for long-range, high-performance IoT deployments.

Wi-Fi HaLow (IEEE 802.11ah) is an advanced wireless technology designed specifically for the Internet of Things (IoT). Unlike traditional Wi-Fi, which operates in the 2.4 GHz and 5 GHz bands, Wi-Fi HaLow operates in the sub-GHz spectrum (900 MHz in the U.S.), offering extended range, lower power consumption, and improved penetration through obstacles. This makes it an excellent alternative to other wireless IoT standards such as LoRa, Zigbee, Bluetooth, and NB-IoT.
