What is frequency range for a simple LAN?

The frequency range for a simple Local Area Network (LAN) typically operates within the 2.4 GHz and 5 GHz bands, especially for wireless networks like Wi-Fi. The 2.4 GHz band supports older standards (like 802.11b/g/n), while the 5 GHz band accommodates newer standards (such as 802.11ac/ax), offering higher speeds and less interference. Wired LANs, using Ethernet, do not have a specific frequency range like wireless networks, as they rely on electrical signals over twisted pair or fiber optic cables.
