Appendix A - 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
frequency to connect wirelessly so you have the freedom to connect computers anywhere in your home or oce network.

How does wireless work?
Wireless works similarly to how cordless phones work, through radio signals that transmit data from one point A to point B. But
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 dierent types of wireless networksl: Wireless Local Area Network (WLAN),
and Wireless Personal Area Network (WPAN).

In a wireless local area network, 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 access
point the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places
like manufacturing plants, industrial locations, university and high school campuses, airports, golf courses, and many other
outdoor venues.
