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 300 feet.
