WiFi isn’t 5G. 5G isn't the same as 5GHz That “GHz” in WiFi just means frequency bands your router works on i.e. 2.4 GHz and 5 GHz (now 6GHz aswell) It’s still RF (Radiofrequency), just a different flavor. 5G, on the other hand, means 5th generation mobile networks that works on on low, mid and millimeter waves (mmWave) WiFi is your inhouse radiation. 5G is the neighbourhood radiation.
