A wireless router is a device that allows the creation of a computer or Internet network without the use of cables. Most routers in the wireless category have LAN ports and a WAN port for the connection to a wide area network. These features enable the user to set the routing functions and even filter them. And since no cables are used for the creation of the network, the router includes wireless antennae for the connection with other wireless equipment. Radio waves are converted into electrical impulses and decoded by the computer/s.
It is a lot more convenient to connect devices without cables, not to mention that wireless technology tends to become cheaper too. The local traffic can be directed on the network using the wireless router alone, but for Internet access, a modem is required as well. The modem is usually pre-configured by the cable or DSL (digital subscriber line) Internet service provider. Your network will thus get connected to the world wide web through the wireless router.
Sometimes the router and the modem are incorporated in the same unit. The connection of the appliances thus gets simpler when there are not so many devices to connect. The wireless router with built-in modem should support any type of Internet connection, DSL or cable. Some devices provide just one type of Internet access, and you have to make sure it matches the kind of Internet connection that you are using.
Every wireless router supports one or more different broadcasting standards, and they are specified according to the Institute of Electrical and Electronics Engineering. The standard is expressed as 802.11. There is always a letter such as b, a, g, n and several others that follows this designation, and this letter stands for the protocol. The protocols vary depending on the signal strength and speed, thus, the quality of the operations in the network oscillates with it. You won’t experience any drops of performance or data errors if you have a quality wireless router; with low quality devices such problems appear whenever the laptop is at a distance from the router.
The best standards you should look for are 802.11g and 802.11n that operate at very high speeds. If there is not a match with the portable Wi-Fi device, the network will not work.
