The basic Wi-Fi system is extremely simple. In a Wi-Fi network, the computers are able to connect to the internet without wires. The Wi-Fi software uses an access point that is internet enabled and is connected using a cable or a modem. Any electronic gadget like a PC, laptop or a PDA can connect to the internet if it lies within 200 feet from the router. But a distance of 100 m is considered for good quality internet connection. The area that is surrounded by the access point delivers great internet access and is known as Wi-Fi hotspot.
The technology
The technology that is employed in the Wi-Fi software is easy to know in terms of radio devices. It is same as walky-talky devices; the difference is just the strength of the signals. A basic walky-talky works in the range of 1000 bits per sec but the Wi-Fi have greater signal strength and can work at a 2.4GHz frequency. The Wi-Fi radios are available in three different versions; the basic difference between them is their working standards. The next vital feature of these radios is that they work on high data rates.
Today the same technology is used in order to provide people with the internet access. The Wi-Fi software are used everywhere in offices, cafes, restaurants, hotels, colleges and schools. There are so many benefits of using the Wi-Fi software.
The technology has developed and has improved our standard of living as Wi-Fi software has helped us in communicating and computing in a better way. There was a time when we used to use the internet connection on our computers and different wires were connected with it. But now we do not have to worry about wires with Wi-Fi software. Now you can sit in any corner of your house and can access internet at anytime. Although Wi-Fi software has provided us with great internet connectivity but there are few risks attached to this technology as well.
The wireless access point allows a person to access internet and other information if he is in the accessible distance. So, it is important to protect your important data and restrict the use of internet. For instance, if you do not take proper precautions then people outside your work or office can access your private information and can misuse it causing a great loss to your business and reputation. Therefore whenever you use the Wi-Fi software, it is important that you also take necessary precautions. The routers can restrict the use of internet outside a particular area. Before installing Wi-Fi software you have to calculate the area and connect routers so that no outside person can use it without your permission. You can even keep your internet connection password protected.
The password protection allows only the authorized people to access internet. The technology is making out life more convenient and easy but there are many hackers and mean people who are misusing the technology so it is always wise to protect your system from such people.
