CompTIA Network+ (N10-008) — Question 51

A technician is installing a high-density wireless network and wants to use an available frequency that supports the maximum number of channels to reduce interference. Which of the following standard 802.11 frequency ranges should the technician look for while reviewing WAP specifications?

Answer options

• A. 2.4GHz
• B. 5GHz
• C. 6GHz
• D. 900MHz

Correct answer: B

Explanation

The correct answer is B, 5GHz, as it offers a larger number of channels compared to 2.4GHz, which is more crowded and prone to interference. The 6GHz band is newer and may not be as widely supported yet, while 900MHz is not a standard frequency for 802.11 wireless networking.
