What is Wireless?

Wi-Fi uses radio frequency 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 cordless phone work, through radio signals to 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 different types of wireless

networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).

Wireless Local Area Network (WLAN)

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 as seen in the picture, 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, college and high school campuses, airports, golf courses, and many other outdoor venues.
