frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office network.

How does wireless work?
Phones that connect wirelessly to a base station work like wireless does, using radio signals to 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)
Every local area network needs 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.
