Jun 23, 2023 · Industry standards groups ratified 802.11n in 2009 with specifications providing up to 600 Mbps of network bandwidth. 802.11n also offers a somewhat better range over earlier Wi-Fi standards due to its increased signal intensity, and it is backward-compatible with 802.11a/b/g gear.

802.11b, 802.11g, and 802.11n-2.4 utilize the 2.400–2.500 GHz spectrum, one of the ISM bands. 802.11a, 802.11n, and 802.11ac use the more heavily regulated 4.915–5.825 GHz band. These are commonly referred to as the "2.4 GHz and 5 GHz bands" in most sales literature.
Dec 27, 2022 · While the last two standards were incompatible with each other, 802.11g is backward compatible with 802.11b. This means that 802.11b wireless network adapters can be used with 802.11g access points. This is the least expensive standard that is still in use.

May 16, 2023 · IEEE 802.11g™, or Wi-Fi 3, was introduced in 2003. It allowed for faster data rates of up to 54 Mbit/s in the same 2.4 GHz frequency band as IEEE 802.11b, thanks to an OFDM multi-carrier modulation scheme and other enhancements. This was appealing to mass market users, as 2.4 GHz devices were less expensive than 5 GHz devices.
Mar 23, 2017 · This standard defines the technical corrections and enhancements to IEEE Std 802.11 for wireless local area networks (WLANs). It covers the medium access control (MAC) and physical layer (PHY) functions for different frequency bands and modes of operation.
