Appendix B - Wireless Basics
What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi
uses radio waves to connect wirelessly, so you have the freedom to connect computers anywhere in your home or
office network.

How does wireless work?
Wireless works similar to how a cordless phone works- using radio signals to transmit data from one point to another.
However, wireless technology has restrictions as to how you can access the network. You must be within the wireless
network range area to be able to connect your computer. There are two different types of wireless networks: a Wireless
Local Area Network (WLAN) and a Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a WLAN, a device called an Access Point (AP) connects computers to the network. The access point has a small
antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor AP, the
signal can travel up to 300 feet. With an outdoor AP the signal can reach out up to 30 miles to serve places like
manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other
outdoor venues.
