WiFi

WiFi is a family of wireless networking standards based on the IEEE 802.11 specification. It allows devices to connect to a local network and the internet over radio frequencies, typically 2.4 GHz or 5 GHz, without physical cables. Each successive generation of the standard (802.11n, 802.11ac, 802.11ax — marketed as WiFi 4, 5, and 6 respectively) has increased throughput, improved efficiency in congested environments, and reduced latency.

WiFi networks are created by wireless access points (APs) that broadcast one or more named networks (SSIDs). Devices associate with an AP, authenticate, and then communicate as if they were on a wired LAN.

In This Home

WiFi coverage throughout the home is provided by UniFi access points managed through the Home Network system. The Enphase IQ Gateway connects to the network via WiFi. ESPHome devices also connect over WiFi to report sensor data and receive commands from Home Assistant.
