Which frequencies are defined by 802.11 for wireless networking? (choose TWO)
A
2.4 GHz
B
5.75 GHz
C
900 MHz
D
1.9 GHz
Explanation: 

Detailed explanation-1: -While both 802.11a and 802.11g each operate at 54 Mbps, 802.11g operates in the 2.4 GHz to 2.4835 GHz range; which will cause interference with the client’s wireless phone system. 802.11a, on the other hand, operates in the 5.725 GHz to 5.850 GHz frequency range; which won’t interfere with the phone system.

Detailed explanation-2: –An 802.11a wireless network running in the 5.725-5.850 GHz frequency range.

Detailed explanation-3: -802.11n operates on both the 2.4 GHz and the 5 GHz bands.

Detailed explanation-4: -802.11a supported the 5 GHz band and a theoretical maximum speed of 54 Mbps. In the early 2000s, many business/enterprise wireless devices used 802.11a Wi-Fi radios. The 5GHz bandwidths allowed for higher speeds than 802.11b and 2.4 GHz.

Detailed explanation-5: –An 802.11a wireless network running in the 5.725-5.850 GHz frequency range.
