Why can't ESP8266 operate in 5Ghz since 802.11n is supported

In the hardware user guide, 802.11 n is supported. If so, why is the frequency range limited to 2.4Ghz? Why can't ESP8266 operate in 5Ghz?

From
https://en.m.wikipedia.org/wiki/IEEE_802.11#802.11n:
802.11n operates on both the 2.4 GHz and the lesser-used 5 GHz bands. Support for 5 GHz bands is optional.

So The esp can operate on 5Ghz right ? it is not limited to 2.4GHz because it uses 802.11n (The 5Ghz is optional) ?
I am asking specifically for esp8266 12E ?
If yes how do we turn it on ?
Thanks !

You misunderstand. The ESP8266 is not designed for 5 GHz. N does not mean that the device can work at 5 GHz. On one ESP8266 data sheet it says, 802.11n support (2.4GHz); There is nothing about 5GHz. N can be used on both frequency bands. It does not mean that a device that has N can do both frequency bands.
