What is the difference between 2.4 GHz and 5 GHz wireless frequencies?

The primary differences between the two frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.

In simple words

• 5Ghz wifi is high speed as well as low area covering because of shorter wavelength
• 2.5Ghz wifi is less speed and more area covered because of low frequency than 5 ghz .
