Wi-Fi (IEEE 802.11) is the backbone of home and office IP connectivity, and in IoTITermIoT (Internet of Things)The IoT (Internet of Things) is the network of physical objects with sensors, software and connectivity that collect and exchange data and act autonomously.View profile it became popular thanks to cheap chips like the ESP8266 and ESP32
HardwareESP32Dual-core WiFi + BT/BLE SoC at €-tier priceView profile, which connect a device directly to the local network and the cloud with no intermediate gateway.
Its advantage is bandwidth and ubiquity; its drawback is power consumption, which makes it ill-suited to long-life battery sensors. For that gap, Wi-Fi HaLow (802.11ah, sub-GHz) offers lower power and far greater range, expressly aimed at IoT.
