Wireless router

Computer networks have greatly enhanced the computing power available to an individual computer by linking the individual computer to other computers and devices. Wireless networks allow computing devices to share information and resources via wireless communications. Examples of computing devices include laptop or desktop computers, personal digital assistants (PDAs), mobile phones, data terminals, data collection devices, and other portable and non-portable computing devices. A wireless local area network (WLAN) is a type of wireless network that typically use high-frequency radio waves carrying digital data to communicate between nodes. Wireless broadband networks make high performance Internet access possible where wired broadband infrastructure is impractical. A wireless router is a router configured for establishing a communication link between the mobile network and an attachment router of a wide area network, such as the Internet, providing connectivity for the mobile network to the wide area network. The wireless router thus serves as a gateway to route packets between the mobile network and the Internet. Mobile wireless routers eliminate the need for a host to be aware of mobility. In wireless routing network, wireless routers with omni-directional antennas are used as a network node. Nodes in the WLAN communicate via transceivers at each node. Each transceiver both transmits and receives radio waves containing digital data. The proximity of the nodes permits the network to operate reliably at low power and at high data rates. Each wireless router can communicate with other nodes, i.e. other wireless routers in any direction. The wireless routers generally comprise three components, namely a TCP/IP protocol suite support, a wireless operating system that optimizes the wireless network performance and robustness, and a high-performance digital RF modem.
