Under many circumstances, it may be desirable for mobile network devices to link to a
conventional Ethernet LAN in order to use servers, printers or an Internet connection
supplied through the wired LAN. A Wireless Router is a device used to provide this link.
What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network
without using wires. Wi-Fi uses radio frequency to connect wirelessly, so you have the
freedom to connect computers anywhere in your home or office network.

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. 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.
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices
in WPAN operate in a range up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but
in return it doesn't use nearly as much power which makes it ideal for personal devices,
such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that
operate on batteries.
