Wireless Armenia

Wi-Fi is a wireless networking technology which is used worldwide. Computers can be connected wirelessly to routers. The routers in turnis then connected to the internet by modem in a WI-FI environment. It uses radio waves to provide internet as well as network connections. It works on the principle of no physical connection between the receiver and the send by using the technology known as Radio Frequency. Currently the mobile phones have also started using the Wi-Fi Technology.
How does Wi-Fi Work
It serves and works on the same way that a wired network will work providing internet facility to computers etc, only different is wires will not be required and therefore it is very easy fast and cheap to setup. As you are aware wired network requires lot of labour intensive effort and are expensive. To be honest there is no such thing as wireless network as usually it is linked to some wired network at some point somewhere.
The wireless networking technology first came into use almost a decade ago and gained popularity and became a rage ever since
In 2003 upgraded version ws introduced which offered higher level of performance ranging from good speed and range
Again in 2009 it was upgraded further. All the Wi-Fi variable use the same amount of radio frequency which is 2.4 Ghz and therefore are also compatible with each other so that one can use various standard in the same network of wireless integration. In an ideal scenario we will want all our devices which are wireless compatible i.e. the access points as well as computers etc use the same same standard technology and from the same vendor which is not always possible
Anyway Wi-Fi has revolutionized the entire workings of computers and mobile phones which before a decade was hard to imagine. Because of the Wi-Fi technology it is possible to work anywhere anytime by most of the individuals.
