Detailed explanation-1: -IEEE 802.11n maintains backward compatibility with IEEE 802.11a/b/g WLANs because it operates on both the 2.4 GHz ISM band and the 5.0 GHz UNII band. Throughput is enhanced over its predecessors by using wider bandwidth channels and devices equipped with multiple antennas to better use RF signal.
Detailed explanation-2: -802.11n operates on both the 2.4 GHz and the 5 GHz bands.
Detailed explanation-3: -802.11n, also known as WiFi 4, was the first one that was “dual-band” enabled (both 2.4 and 5 GHz frequencies). 802.11ac, also known as WiFi 5, is the current standard. 802.11ax, also known as WiFi 6, is the next-gen WiFi standard. Each new standard comes with improvements in speed and efficiency made over time.
Detailed explanation-4: -In addition to these multi-user efficiency enhancements, Wi-Fi 6 (802.11ax) radios will be backward compatible with 802.11/a/b/g/n/ac radios. Please note that unlike 802.11ac radios, which can transmit only on the 5 GHz frequency band, 802.11ax radios can operate on both the 2.4 GHz and 5 GHz frequency bands.
