Wireless Master

As the days pass by. Technology seems to be getting more and more advanced. A few decades back, having a computer seemed to be a big thing for most people. Folks stared at you in awe when you mentioned that you had a computer at home. Then came the Internet and the whole world was at your feet. People all over the world could connect within a matter of seconds as a result of this technology boom. Now people stare at you if you tell them that you DONT have a computer. Things change and with it, the times do as well. Now there seems to be a further improvement or progress, call it what you will. All these days you probably had to stick your computer in one corner as that was how far the internet cable would go. Now you can run around with your laptop all around the house and even use it in cafes or certain other spots. What am I talking about, you ask? The magic word is Wi-fi, my friend. Now if you do not know what that is, then you have some serious catching up to do. The world has moved ahead, yet again, and as it does, all the time. Well, if you really do not know what Wi-fi is, then here is a bit of dirt on that.

Wi-fi is a trademark of the Wi-Fi Alliance. This applies for those products which have been manufactured on the basis of the IEEE 802.11 standards. This is a certification of a kind and guarantees a communication link between wireless gadgets. In many countries, the term is used to mean IEEE 802.11-wireless LAN (WLAN). The technology of Wi-Fi is used by personal computers, video gaming consoles, laptops, smartphones, printers and a host of other peripheral devices.

The technology that is used by Wi-Fi is of two types. These are called single carrier direct-sequence spread spectrum radio technology and multi-carrier OFDM (Orthogonal Frequency Division Multiplexing) radio technology. Because of the unlicensed spread spectrum, Wi-Fi has outgrown its competitors like HomeRF and Bluetooth.

If a device has Wi-Fi facilities then it can receive Internet connectivity if it is within the range of a Wi-Fi network. This device can be a personal computer, a laptop, a gaming console, a smartphone and many others as well. The areas of Wi-Fi connectivity are called “hotspots”. The range of such a network can be a small room to may square miles in terms of distance. This technology has not only been used in homes and offices, but also in many public spaces like hotels, cafes, campuses of educational institutions and even airports, for that matter. Wi-Fi facilitates P2P connectivity or what is called the wireless ad hoc network. Through this many Wi-Fi enabled devices are able to connect with each other directly. The potential usage of this technology is immense. So many devices can connect to each other seamlessly and that too, without any hiccups whatsoever.
