Wireless Fidelity (Wi-Fi) is a wireless networking technology that uses radio waves to provide high-speed, wireless internet and network connections. This technology is based on the IEEE 802.11 standards, including the 802.11a and 802.11b (IEEE, 1999). This technology has proven to be the fast-wireless networking approach that is relatively easy and inexpensive to implement (Steven J. Vaughan-Nichols, 2003). This is made possible by using wireless Access Point (AP) or hotspots. The AP will broadcast the signal to Wi-Fi-capable devices within the AP's range. Capable devices can be, from laptops to cellular mobile devices and PDA's.
