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 wire-
less 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.
