The main difference between 2.4 GHz and 5 GHz radio frequencies is the Range and bandwidth.
Range
How far your data can travel. In most cases, the higher the frequency of the wireless signal, the shorter the range.
The biggest reason is that higher frequency signals cannot penetrate solid objects such as walls and floors, as well as lower frequency signals. Therefore, the range of 2.4 GHz is farther than the frequency of 5 GHz.
Bandwidth (speed)
Higher bandwidth means that files will be downloaded and uploaded faster, while high-bandwidth applications (such as streaming video) will perform smoother and faster.
Higher frequencies allow faster data transmission, also known as bandwidth. Therefore, 5GHz with higher bandwidth will provide faster data connection than 2.4GHZ.
Choosing the best frequency
Many devices use only 2.4 GHz frequencies, and these devices try to use the same “radio space,” which can lead to overcrowding. There are 23 available channels available for the device in the 5GHz band and 3 available channels in the 2.4GHz band.
Overcrowding and interference can cause slowdowns and lead to connection problems. Some examples of devices that may cause interference:
• Microwaves
• Cordless phones
• Baby Monitor
• Garage Door Opener
So Which is best for you:
• 5GHz is usually better than 2.4GHz if faster speeds are the most important to you.
• If the wireless range is more important to you, 2.4 GHz is usually better than 5 GHz.
• If you have a lot of devices that use 2.4 GHz, and you experience problems with interference or internal connections, then 5 GHz may be the better choice.
