In terms of frequency, what advantage does 2.4 GHz have over 5 GHz?

The advantage of 2.4 GHz over 5 GHz primarily lies in its ability to penetrate walls and obstacles more effectively. The lower frequency allows radio waves to travel further and better navigate through physical barriers like walls, floors, and furniture. This characteristic is particularly beneficial in environments where wireless signals must reach devices situated in different rooms or on different floors.

In contrast, the 5 GHz frequency provides higher data rates and bandwidth capabilities, but it has a more limited range and is more easily obstructed by obstacles. Consequently, while 5 GHz is often preferred for high-speed internet access at closer ranges, 2.4 GHz is favored for broader coverage and reliability in environments with many barriers. The cost of equipment and data-carrying capacity do not directly relate to the frequency advantages in this context.
