Detailed explanation-1: -802.11n supports multi-channel utilization and operates at both 2.4 GHz and 5 GHz bands. The maximum data rate for this wireless networking standard is 600 Mbps and it provides backward compatibility with its predecessors.
Detailed explanation-2: -IEEE 802.11n devices can provide a data rate of up to 600 Mbps and supports both 2.4/5 GHz bands. This maximum data rate of 600 Mbps increases the throughput 10x that of the 802.11g network. It can achieve a data rate from 54 Mbit/s to 72 Mbit/s with a single spatial stream in a 20 MHz channel with one antenna.
Detailed explanation-3: -Whereas 802.11ac works only in the 5 GHz band, 802.11ax operates in both the 2.4 GHz and 5 GHz bands. While the 802.11ac standard allowed up to eight spatial streams, it cannot deliver more than 6.9 Gbps due to hardware limitations.
