What is one key difference between 5GHz and 2.4GHz?

The distinction captured in the correct answer pertains to the characteristics of the two frequency bands in wireless communications. The 5GHz band is indeed capable of supporting higher data rates compared to the 2.4GHz band, which allows it to handle more data effectively. However, this enhanced data capacity comes with a trade-off in terms of range and penetration.

The 5GHz frequency has shorter wavelengths, which means it does not propagate as well through obstacles such as walls or furniture as the longer wavelengths of the 2.4GHz frequency do. Consequently, while 5GHz can deliver faster speeds and handle more data, its effective range is more limited, especially in environments with physical barriers.

This understanding of the operational parameters helps clarify why 5GHz is often favored for high-bandwidth applications, like streaming and gaming, in environments where devices are in close proximity to the router, while 2.4GHz might be chosen for broader coverage in larger spaces or areas with obstructions.
