Detailed explanation-1: -802.11n is backward compatible with its predecessors. Wireless n works properly with 11a/b/g standards. Right now let us examine the g and n standards. Both IEEE standards work in the same frequency( 2.4GHz).
Detailed explanation-2: -* Integrating 802.11n into your Wi-Fi network It has been widely reported that 802.11n, the wireless LAN IEEE draft standard that uses multiple input/multiple output technology to boost Wi-Fi speeds to over 100Mbps, is “backward compatible” with today’s 802.11a, 11b, and 11g networks.
Detailed explanation-3: -Because 802.11ac is backward compatible with 802.11n and most 802.11ac routers are dual-band (2.4 & 5 GHz) in practice, for most of us this all boils down to: 802.11ac vs 802.11ax. When you consider cost and how common support for the two standards is, 802.11ac is often the right answer today.
Detailed explanation-4: -802.11g hardware is fully backward compatible with 802.11b hardware.
Detailed explanation-5: -In real world tests, 802.11n base station is established to be 3.8 times faster than the 802.11g setup. 802.11a offers the same theoretical speed (54 Mbps) as 802.11g, but it operates in a different frequency (5 GHz) and is not backwards compatible with 802.11b.
