Chapter 7 Wireless

P-873HNUP-51B User’s Guide

“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and 
receive information over the airwaves, wireless networking devices exchange information with one 
another. A wireless networking device is just like a radio that lets your computer exchange 
information with radios attached to other computers. Like walkie-talkies, most wireless networking 
devices operate at radio frequency bands that are open to the public and do not require a license to 
use. However, wireless networking is different from that of most traditional radio communications in 
that there a number of wireless networking standards available with different methods of data 
encryption.
