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.

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.
