What is a wireless router?

The router is a device used to flow between local computers connected together, either via Ethernet wiring or through radio wool technology. The network that uses Ethernet cabling is referred to as a firm network, while radio wool networks are called wireless networks. Both types of networks have advantages and disadvantages, but wireless networks are the least costly and easiest to set, because they do not require the running of the Ethernet cable between the machines. Standard routers do not have built -in wireless technology, so if you want a wireless network, you will require a wireless router.

While a wireless router can direct local traffic on the network, a modem is required if access to the Internet. In many cases, digital subscribers (DSL) and cable internet service providers (ISP) provide a pre -configured modem to connect to the service. This type of router can be connected to the modem to provide access toInternet to the network.

Another option is to get a wireless router with a built -in modem to reduce the number of desired devices. The highest quality products in this line come up with instructions for the configuration of a built -in modem that connects to popular national providers of Internet services, usually trivial exercises for anyone who has a little computer experience. If you decide to get one with a built -in modem, you will need to know what type of Internet access (cable or DSL) or you want a router that supports both types.

There are several broadcast standards and the wireless router will support one or more, but not all of these standards. Wireless network specifications are determined by the Institute of Electrical Engineers of Electrical and Electronic Engineers (IEEE) and are known as 802.11 standards. The letter is governed by this designation as in 802.11 n , which shows which protocols that the router supports. The difference between Protocols (eg 802.11b, 802.11a, 802.11g, 802.11n…) is signal strength and speed. Radio waves spread in a circular pattern, out of the router. The stronger the signal, the further you can place your computer or walk with a laptop and still get a good signal. As the force disappears, the power decreases, creates data errors and signed signals.

In the fourth quarter of 2008, the standard Legacy 802.11g. The wireless router, which supports 802.11g, operates in the 2.4 GHz band and culminates at a speed of about 54 megabits per second. The newer standard, which is to be completed in 2009, is 802.11n, operating in the 5 GHz band. One that supports the 802.11n standard can deliver up to four times the 802.11g router. Keep in mind that each computer in the network will require an internal wireless card or an external portable WiFi device that supports the same protocol as the router.

businesses are already using the Standard Legacy 802.11g might want to add a new networkVé computers using Faster 802.11n Standard. In this case, there may be a dual -band wireless router that supports both the 2.4 GHz 802.11g standard, and the 5 GHz 802.11N standard may be the answer. Double belt routers will be more expensive because they contain two radios. If you set up a net for the first time and do not require a wireless double belt router, you can save some money by holding on a single band model.
