How does wireless work?
Wireless works similar to how cordless phones work, through radio signals that transmit data from 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, 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.
