Wireless Router

A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point and a network switch. It is commonly used to provide access to the Internet or a computer network. It does not require a wired link, as the connection is made wirelessly, via radio waves. It can function in a wired LAN (local area network), in a wireless-only LAN (WLAN), or in a mixed wired/wireless network, depending on the manufacturer and model.

Most current wireless routers have the following characteristics:

• LAN ports which function in the same manner as the ports of a network switch.
• A WAN port which connects to a wide area network, typically one with Internet access. External destinations are accessed using this port.
• A wireless antenna that allows connections to other wireless devices, such as NiCs, wireless repeaters, wireless access points, and wireless bridges. This antenna typically uses the Wi-Fi standard.
• Wireless router has many types of security for different manufacturers.Ex-WEP,WAP,WPA.

Some wireless routers also include a DSL or cable modem in addition to the other components.
