What Is Wi-Fi

Wireless technology has become a prominent field in the area of networking. It has many uses. The most important being portability and mobility. With the help of wireless technology people now can send and receive messages, phone calls, faxes, read files, login on remote machines etc. and perform all the above mentioned duties from anywhere on land, sea, or air.

The technology of wifi has stormed the field of wireless networking. There are numerous applications of wifi. Nowadays it is very useful and critical in business world because today's business gives more emphasis on the communication of the information. Wifi also finds usage at home, workplaces, shops, any public places etc. the study of the advantages and the risks involved in the wifi system is necessary in order to exploit the full use of it.

About wireless networks.

The transfer of information from node to another with the help of electromagnetic waves is referred to as wireless communication. Signals are normally broadcast through free space and are available to anyone who has device capable of receiving them. A new technique of wireless data transmission known as wifi (wireless fidelity) has been developed. Wifi uses the radio waves to transmit the data. It uses the frequency of 2.4GHz and uses SSID for addressing purposes. SSID stands for Service Set Identifier. It uses a set of characters or numbers addresses so that the sending access point can be identified. Any access point which wants to receive the signal must have the same set of SSID as that of sender's SSID.

Advantages.

The usage of wifi system has numerous advantages. The most important advantage is the cost factor. Since there are free hotspots or access points, a free connection between two nodes cab be established in the network.
A wireless network also provides the facilities of mobility. Hence it is now possible to have a wireless connection, free of hard wired connections.It is also easy to install and configure wifi network. It is also easy and generally faster, internet connections are possible by wifi networks.

Dangers and risks.

Since wifi is a wireless connection it uses the shared wireless space. Hence it is possible that many signals of similar frequencies can interfere with each other and cause unnecessary distortions. This leads to the loss of data and the received data may get corrupted. Hence wifi does not ensure an error free connection.
Another danger involved is related to security of data. It is possible that users who are new to the wifi network may setup an insecure access point, without setting the various security configurations.
It is also possible that some miscreants may use the same default SSID everywhere to access the secured access points illegally. The best way to counter these dangers is to learn and study the configuration of the secured network and make it a rule to always use a different SSID for access point and never keep the default value.

WiFi Access Point



The field of communication is the fastest growing field in science and technology. The advancement in wireless communication was started in 1901 with development of wireless telegraph using Morse code. Wireless networks have many uses, people on the road now can send messages, data, mail, files etc from anywhere in the world. With advancement in the internet technology in the 1980's there is an ever increasing interest in wireless networking.

A network is a group of connected communicating devices such as computer. An internet is a collaboration of more than hundreds of thousands interconnected networks. Private individuals as well as various organizations such as government agencies, schools, research facilities, corporations and libraries in more than 100 countries use the internet.

The internet has revolutionized many aspects of our daily lives. It has affected the way we do business as well as the way we spend our leisure time. Count the ways you've used the internet recently. Perhaps you've sent electronic mail (e-mail) to a business associate, paid a utility bill, read newspaper from a distant city, or looked up a local movie schedule- all by using the internet. Or maybe you researched a medical topic, booked a hotel reservation, chatted with a fellow Trekkie, or comparison-shopped for car. The internet is a communication system that has brought a wealth of information you or fingertips and organized it for our use.
A new technology known as wifi which stands for wireless fidelity was developed which enables the users to transmit data at a fast rate. The whole concept of wifi is based on access points.

Access points.

An access point can be thought as a hardware device or a software which establishes a wireless communication. this access point gets connected to wired local area network such as DSL, cables. Any two systems which are wifi enabled can thus connect without the need of physical connection. It improves the mobility if the nodes.

The access point also allows the user to have a faster connection by providing better bandwidth. Now it is possible for a user to watch movies, download software and play multiplayer games all at the same time, this is all made possible by wifi connection which provides a superior bandwidth over existing networks.

In order to utilize a wifi network to its maximum we should properly understand the basics of it. We should understand the meaning of access points and should know how to install and implement them. As there are numerous benefits of these wifi networks,
