May 24, 2022 · What frequencies does Wi-Fi use? Wi-Fi uses ultra high frequency and super high frequency ranges in the radio spectrum. Most routers broadcast Wi-Fi signals with 2.4 GHz and 5 GHz, although some may include a 60 GHz connection.

Sep 4, 2024 · Most Wi-Fi routers offer 2.4 GHz and 5 GHz frequency bands, and some modern Wi-Fi 6E or Wi-Fi 7 routers also include the 6 GHz frequency band. The Wi-Fi frequency you should use depends on a number of factors, including your location, what activities you’re doing, and what frequencies are available. One of the most important features of a ...
All Wi-Fi technologies are built to a specific Wi-Fi standard, which also specifies the frequency bands to which they can connect. Wi-Fi 4 built to the 802.11n standard from 2007 came in two different versions: 802.11bgn, which could only access 2.4 GHz bands, and 802.11agn, which was dual band and able to connect to 2.4 GHz and 5 GHz bands.
Different versions of Wi-Fi use different techniques, 802.11b uses direct-sequence spread spectrum on a single carrier, whereas 802.11a, Wi-Fi 4, 5 and 6 use orthogonal frequency-division multiplexing. [86] [87] As with other IEEE 802 LANs, stations come programmed with a globally unique 48-bit MAC address.
Jan 12, 2021 · Wi-Fi devices made by different companies can talk to each other. This is because they follow a common set of rules called the 802.11 standards , published by the Institute for Electrical and ...

The 5 GHz band offers less coverage but transmits at faster speeds than the 2.4 GHz band. The 6 GHz band provides the least coverage but transmits data at superfast speeds. WiFi 7 technology “MLO” feature grants the ability to combine frequency bands in a single connection. Learn more about WiFi 7 technology.
