Wireless Router

The wireless router functions as not only a router but also a wireless access point and a network switch. It is often used to provide access to a computer network or the Internet. Since the connection is made via radio waves, it does not require a wired link. It can function in a wired LAN (local area network), a wireless-only LAN (WLAN), or a mixed wired/wireless network.

Most existing wireless routers have the following features:
1. A LAN port that functions in the same manner as the port of a network switch.
2. A WAN port which connects to a wide area network. External destinations are accessed by using this port.
3. A wireless antenna which allows connections to other wireless devices, such as NiCs, wireless bridges, wireless repeaters, and wireless access points. This antenna typically complies with the Wi-Fi standard.
4. Many types of security: WAP, WPA, and Ex-WEP.

In addition to the other components, some wireless routers also include a DSL or cable modem.
