Wireless technology has developed into a famous field in the area of networking. It has lots of uses. The most significant being portability and mobility. With the assist of wireless technology people now can propel and receive messages, phone calls, faxes, read files, login on remote machines etc. and perform all the above talk about responsibility from anywhere on land, sea, or air.
The technology of Wi-Fi has tempest the field of wireless networking. There are many applications of Wi-Fi. Nowadays it is very helpful and dangerous in business world because today’s commerce gives more stress on the communication of the in order. Wi-Fi also finds custom at home, workplaces, shops, any public places etc. the revise of the reward and the risks involved in the Wi-Fi system is essential in order to develop the full make use of it.
Wireless networks.
The move of information from node to another with the help of electromagnetic waves is referred to as wireless communiqué. Signals are in general broadcast from end to end free space and are available to anybody who has device capable of receiving them. A new technique of wireless data transmission recognized as Wi-Fi (wireless fidelity) has been urbanized. Wi-Fi uses the radio waves to broadcast 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 font or numbers addresses so that the sending right of entry point can be identified. Any right of entry point which wants to take delivery of the signal must have the same set of SSID as that of dispatcher SSID.
Advantages
The usage of Wi-Fi 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 Wi-Fi network. It is also simple and usually faster, internet connections are possible by Wi-Fi networks.
Disadvantages
As Wi-Fi is a wireless connection it employs the shared wireless space. Hence it is possible that much indication 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. Therefore Wi-Fi does not make sure an error free association. Another danger involved is related to security of data. It is possible that users who are new to the Wi-Fi network may setup an insecure admission point, without setting the various security configurations. It is also probable that some miscreants may use the same default SSID everywhere to admission the secured access points illegally. The best way to counter these dangers is to learn and revise the pattern of the protected network and make it a rule to always use a dissimilar SSID for right of entry point and never stay put the absence value.
