Which of the following IEEE 802.11 standards supports the 2.4 GHz frequency band only?
Which of the following IEEE 802.11 standards supports the 2.4 GHz frequency band only?
802.11g is the IEEE 802.11 standard that supports only the 2.4 GHz frequency band. 802.11a operates in the 5 GHz frequency band, 802.11n can operate in both the 2.4 GHz and 5 GHz bands, and 802.11ax operates in the 2.4 GHz, 5 GHz, and 6 GHz bands.
The answer is B. 802.11g The correct answer is B. 802.11g. Here's why: 802.11a: Operates in the 5 GHz frequency band. 802.11b: Supports both 2.4 GHz and 5 GHz bands. 802.11g: Supports only the 2.4 GHz band. 802.11n: Supports both 2.4 GHz and 5 GHz bands. 802.11ax: Supports both 2.4 GHz, 5 GHz, and 6 GHz bands. Therefore, only 802.11g operates exclusively in the 2.4 GHz frequency band.
The answer is C. 802.11g
The answer is B,C and D
Answer is A. The key word here is only 802.11a supports only 5Ghz band 802.11n and 802.11ax supports both 2.4 & 5Ghz band

B. 802.11g Explanation: 802.11g operates in the 2.4 GHz frequency band and provides backward compatibility with 802.11b. It does not support the 5 GHz frequency band. 802.11a operates in the 5 GHz frequency band. 802.11n and 802.11ax can operate in both the 2.4
802.11b - 2,4GHz
802.11b 2,4GHz
