Question

Both Wireless LANs (WLANs) and Wireless WANs (WWANs) rely on the_____as the communication medium. ​
A) multiplexer
B) CIA triangle
C) controller
D) radio frequency spectrum

Quizplus · Accepted Answer

Both WLAN and WWAN use the radio frequency spectrum as the communication medium. WLANs use unlicensed frequencies in the 2.4 GHz or 5 GHz band, while WWANs use licensed frequencies in bands reserved for cellular communication, such as 3G, 4G, or 5G. Multiplexers and controllers may be used in the network architecture of WLANs and WWANs, but they are not the communication medium. The CIA triangle is a security model used to ensure data confidentiality, integrity, and availability, and it is not directly related to the communication medium used by wireless networks.
