Wireless Fidelity, or commonly known as “Wi-Fi”, is the name used to denote the wireless networking technology that had became famous at providing a very fast wireless Internet as well as network connections while making use of radio waves.
The business group that has the possession over the Wi-Fi is known to be as the Wi-Fi Alliance.
According to the Wi-Fi Alliance, Wi-Fi is generally any products that act as wireless local area network or WLAN, which are derived from the standards established by the Institute of Electrical and Electronic Engineers or IEEE 802.11.
As defined by the experts, RF is a type of frequency that belongs to the electromagnetic spectrum and it is related to what is considered to be as radio wave propagation.
Wi-Fi functions in such a way that there is not a single physical wired connection that links a sender to its receiver and it only utilizes the technology that centers on radio frequency or RF.
Sending a current of radio frequency to an antenna allows production of an electromagnetic field and this field allows dissemination of the RF through the space.
Generally speaking, the most important aspect of a wireless network is the access point (AP).
The key purpose of the access point is the distribution of the wireless signal, which is then identified by a computer.
Upon spotting, the computer system will then tune into the wireless signal.
Computers, however, should have wireless network adapters so as to have the capability to create a connection with the access point.
The 2.4 GHz Wi-Fi is most frequently used compared to the other frequencies existing today.
This has been confirmed after series of tests which proved that Wi-Fi in a 2.4 GHz frequency block truly traverses a larger range when compared to when the Wi-Fi in 5GHz frequency block is being utilized.
But then, there are times when jamming occurs on some channels because the default setting of the 2.4 GHz 802.11b and 802.11g settles on similar channels during start-up.
Hence, there is a great need for a user to alter the setting of his or her machine so as to modify the channel of operation for a specific access point.
