What is WiFi?

The internet revolution has brought a lot of things to the table when we think about the types of technology that many people use today. From broadband connections to WiFi services all the way to WiFi-enabled cell phones, there is certainly a plethora of information and hardware devices that are on the market today that weren't here just five or ten years ago! Needless to say, WiFi is here to stay and there's nothing anyone can do about it! It has definitely improved a lot of lives throughout the years that it's been introduced.

But what exactly is WiFi and why are people using it more than before? To answer the question of what WiFi really is one must understand how it works. The simplest way to explain how WiFi works is to ask someone to imagine a pair of walkie-talkies that are communicating with each other. The WiFi capable devices, like laptops, communicated with authenticated WiFi main stations by a series of walkie-talkie communications: one sends the other a signal while the signal is transferred back to the main station.

There are many uses for WiFi technology in our world. First and foremost, WiFi connections are a good way for everyone to have an internet connection whenever they want. Millions of consumers in the United States have already added WiFi capable devices and WiFi connections in their homes because it is not only less expensive to have and to manufacture, but it also gives them a faster and better internet connection than dial-up did only several years ago.

Secondly, WiFi is a technology that is meant for people on the go. The WiFi services that we are so accustomed to allow individuals to connect their wireless devices, such as laptops and pocket pc handhelds, to any other WiFi or wireless network that they come in contact with. However, the networks that are securely protected with a password, such as those of colleges and universities, are not able to be connected to by just anyone. But if there is no password that's attached to a WiFi network then anyone is free to connect, disconnect, and re-connect to the WiFi internet network any time of the day that they want.

The reason that WiFi technology is great for anyone who travels frequently and even daily is because WiFi allows business men and women to literally take their work with them when they go on business trips. With WiFi connections instead of dial-up connections there are employees who are still able to keep in touch with their companies while on business travel purposes without having to deal with a corded phone or a pager.

College students and just anyone looking for a faster connection also find WiFi devices real convenient. College and university students are able to connect their laptops to wireless networks any time of the day so that they are able to stay in contact with professors and to upload their course work. Furthermore, universities and colleges across America and the world have jumped on the WiFi bandwagon in order to make life easier for their faculty, staff, and students!

Anyone searching for a WiFi network to connect to does not have far to travel. There are many places that receive WiFi connections today, but tomorrow and years down the road there will definitely be a lot more!
