What are the main differences?
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 distances but transmits data at slower speeds. The 5 GHz band provides shorter distances but transmits data at faster speeds.
Why is 5 GHz shorter range, but faster?
The range is lower in the 5 GHz band because higher frequencies cannot penetrate solid objects, such as walls and floors.
However, higher frequencies allow data to be transmitted faster than lower frequencies, so the 5 GHz band allows you to upload and download files faster.
What else affects Wi-Fi speeds?
Your Wi-Fi connection on a particular frequency band can also be faster or slower because of interference from other devices, and from physical surroundings (metal, concrete, thick walls, etc.)
Many Wi-Fi enabled technologies and other household devices use the 2.4 GHz band, including microwaves and garage door openers. When multiple devices attempt to use the same radio space, overcrowding occurs.
The 5 GHz band tends to have less overcrowding than the 2.4GHz band because fewer devices use it
Additionally, the 5 GHz band has 23 channels for devices to use, while the 2.4GHz band has only 11 channels. If you’re experiencing a lot of interference from other devices, consider switching your channel, or using the 5 GHz band.
