A router is a device that acts as a middleman between two different networks. When data is sent between different locations, the router in-between redirects the data to the appropriate location. It is a device in computer networking that forwards data packets to their appropriate destinations, based upon their addresses. Wireless routers are connected to the network at a certain location, and communicate with the rest of the network wirelessly, through the wireless access points inside them. You will find that wireless technology has made it very simple and easy for people to start their own wireless network in their home, with the help of a wireless router. With the help of an antenna, these routers convert and broadcast signals received via telephone wires, which are then picked up by wireless-enabled devices. These wireless routers are mostly included in wireless broadband packages, and are popular in homes where multiple computers need to be connected to the internet at the same time. In a nutshell, wireless routers provide internet access to wireless-enabled devices, such as computers and laptops.

It is easy to get confused with the variety of wireless routers in the market, as most of them resemble each other in looks and features. But you need to remember that not all routers are created the same, hence their task will slightly differ in every network. It is best to read reviews about various products, and do a bit of comparison shopping before you purchase your wireless router. Here are some common queries regarding Wireless routers.

How does a Wireless Router Work?

A wireless router works in a similar manner to a cordless or mobile phone. This is a device that uses radio frequencies to transfer data among the systems in a network. It is connected to a broadband cable or other Internet connection, and with the help of radio frequency wireless waves, it broadcasts and collects wireless signals. In this way, it enables data communication from one location to another. The data from one computer is converted into a wireless radio signal before it is communicated to another computer. The router receives data from the Internet or another network, converts it into wireless radio signals and transmits it to the appropriate computer on the network. The receiving computer converts it back into a digital format that it can understand. The router can also receive a wireless response from the computer, and route it to the Internet/another network.

A wireless router works along with a wireless network card or adaptor, which can be easily installed on your computer or laptop. Both the adaptor and the computer must work within the same frequency range, in order to allow transmission of data back and forth.
