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.
