I don't understand how an ESP8266 can use 2.4 GHz WiFi when its clock is less than this.
This question came to me because when looking for a microcontroller. I always find it weird that 400 MHz+ is a top of the line microcontroller.
The Arduino uses 16MHz and can still use a WiFi module. How or what did i get wrong?
Note: while the question How is the esp8266 is able to generate 2.4 GHz wifi signals? sounds close it is definitely not my question.
To clear it up more, the WiFi signal is sent across 2.4 GHz frequency when the ESP sends or especially receives signals, how could it take info from 2.4 GHz while it only uses 80 MHz?
The answer (as I understand) is that it doesn't use the 2.4 GHz as the data it adds the data with some type of circuit to it, so for example the data exchange can't exceed the clock of the processor (not considering the clock cycles to make this data and process it) so simply a signal of 2.4 GHz carries another small signal of data.
