What is the wavelength of a 5ghz signal?

The new network Millimeter waves use frequencies from 30 to 300 gigahertz, which are 10 to 100 times higher than the radio waves used today for 4G and WiFi networks .1 Şub 2021

WiFi actually operates at quite precise frequencies, either 2.4 GHz or 5 GHz, which correspond to wavelengths of either 12 cm or 6 cm .

4G networks use frequencies below 6 GHz, while 5G will use much higher frequencies in the 30 GHz to 300 GHz range . The larger the frequency, the greater its ability to support fast data without interfering with other wireless signals or becoming overly cluttered.
