A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point. 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.
