An administrator needs to implement a 2.4GHz WLAN that requires multiple APs. Which two are characteristics of the 2.4GHz channels? (Choose two.)
- They can provide faster data transmission for wireless clients in heavily populated wireless networks than 5GHz channels.
- Each channel is separated from the next channel by 20 MHz.
- There are 11 channels for North America identified by the 802.11b standard.
- If three adjacent APs are required, the non-overlapping channels 1, 21, and 41 are recommended.
- Each channel is allotted 22 MHz bandwidth.
Explanation: The 2.4 GHz band is subdivided into multiple channels. Each channel is allotted 22 MHz bandwidth and is separated from the next channel by 5 MHz. If there are three adjacent APs, use channels 1, 6, and 11. The 802.11b standard identifies 11 channels for North America. 5GHz wireless can provide faster data transmission for wireless clients in heavily populated wireless networks because of the large amount of non-overlapping wireless channels.
