Which of the following technologies has more non-overlapping channels to utilize in a wireless LAN?
The correct answer is A. 802.11a. 802.11a operates in the 5 GHz frequency band, which provides up to 23 non-overlapping channels (varies by regulatory domain). In contrast, 802.11b operates in the 2.4 GHz band, which has only 3 non-overlapping channels (1, 6, and 11). 802.11i is a security standard (WPA2), not…

Explanation
802.11a operates in the 5 GHz frequency band, which provides up to 23 non-overlapping channels (varies by regulatory domain). In contrast, 802.11b operates in the 2.4 GHz band, which has only 3 non-overlapping channels (1, 6, and 11). 802.11i is a security standard (WPA2), not a frequency/channel specification. Bluetooth also uses the 2.4 GHz band with frequency hopping, not fixed channels. The wider 5 GHz spectrum of 802.11a is a key advantage for dense wireless deployments.
