Which three Wi-Fi standards operate in the 2.4GHz range of frequencies? (Choose three.)

  • 802.11ac
  • 802.11a
  • 802.11n
  • 802.11b
  • 802.11g
Explanation & Hint:

The Wi-Fi standards that operate in the 2.4GHz range of frequencies are:

  1. 802.11n – This standard can operate in both 2.4GHz and 5GHz frequencies.
  2. 802.11b – This was one of the first Wi-Fi standards, operating solely in the 2.4GHz frequency.
  3. 802.11g – This standard also operates in the 2.4GHz frequency and was designed to be faster than 802.11b while maintaining compatibility with it.

The 802.11ac standard operates exclusively in the 5GHz frequency range, and 802.11a also operates in the 5GHz frequency range, not in the 2.4GHz range.
