Wi-Fi

Introduction

Wi-Fi is a trademark title, also spelled as Wi-Fi, is a form of technology which enables electronic gadgets to perform data exchange or connect to internet using wireless connectivity via a 2.4 GHz as well as 5 GHz SHF broadcasting waves. Ideally, Wi-Fi alliance provides a definition of Wi-Fi as Wireless Local Area Network (WLAN) components based on the Institute of Electrical and Electronic Engineers (IEEE) for the 802.11 standards. Nevertheless, from the fact that majority of WLANs have been built on the above standards, Wi-Fi could also be used in common English for the WLAN. In this regard, the Wi-Fi products with full Wi-Fi Alliance interoperability qualifications testing that have been recognized have the capacity and the right to use the trademark of “Wi-Fi Certified” (Wei & Dixit et al. 2013).

Indeed, most devices may use Wi-Fi technology. Among them: Smartphones; PCs, tablets, video-game consoles as well as digital audio gadgets. These gadgets can connect to network sources such as the Internet through a wireless network access point. These points have a range of approximate length, 20 meters in indoor setting, while the outdoor settings may be longer. Indeed, the average of a single access point may be composed of small area such as a single room with solid walls blocking radio waves. Similarly, the access point may also have a wide scope as large as several square kilometres, which could be achieved through multiple access points in an overlap. However, Wi-Fi technology can be relatively insecure compared to the wired connectivity such as Ethernet (Lee & Choi 2008).

The reason behind the latter argument is that any intruder wishing to disrupt connections does not require any physical connection to the net or technical devices using this net. For instance, WebPages that employ SSL are perceived to be more secure than unencrypted internet connection that can be easily distorted or detected by intruders. Consequently, in order to promote...
