Esp01 in 5G

can we use ESP01 to detect 5G wifi? How? Any modifications needed? Thank you!

Hmmm. Wrong forum? But my guess is no. I believe 5g runs on. 5ghz and the esp8266 is 2.4ghz.

The ESP8266 and regular ESP32 chips only support 2.4GHz WiFi.
The new ESP32-S2 chips support 5GHz WiFi, if you can get hold of them.

Pete.
