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 00 feet. With an outdoor access point the signal can reach out up to 0 miles to serve
places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other
outdoor venues.
