Why does a mobile phone connect to a 150/300/Mbps router with a speed of only 72 M (or 65 M )?

After the Android phone successfully connects to the GHZ wireless signal of the 11N router, the current wireless speed is usually 72 Mbps (or 65 Mbps) on the phone, as shown in the figure below:

Note:: The wireless rate cannot be viewed on iOS mobile phones.

This is because the Wi-Fi module of the mobile phone only has one built-in antenna and only supports 20 MHz bandwidth. Therefore, after the mobile phone connects to the wireless signal of the 11N router, the maximum wireless rate of a mobile phone is 72 Mbps (or 65 Mbps ).
