Many routers combine the two frequencies into one network name. That’s why you might be able to get better range from your router by forcing your phone or laptop to connect to your router’s 2.4GHz network. (Incidentally, this is why 5G is promising such fast speeds, because it uses much higher frequencies-called millimetre wave-but these signals have a tough time getting through glass, trees and even rain.Ģ.4GHz, on the other hand is better at delivering a signal over a greater distance, at slower speeds.
The higher the frequency, the shorter the wavelength. And 5GHz signals cannot penetrate walls, ceilings, desks, and, yes, people as well as 2.4GHz signals. Many people think the latter is better because it offers faster speeds. Wi-Fi can use one of two frequency bands: 2.4GHz or 5GHz.
