The complexity of WiFi is usually too difficult for the average person to understand. To break it down, WiFi is an internet connection that uses two types of radio technology: a single carrier and a multi-carrier. The single carrier type of radio technology, direct sequence spread spectrum radio technology, was the reason behind unlicensed spread spectrum whose regulations enabled the development of WiFi as well as other wireless technology such as cordless telephones, Bluetooth, etc.The father of WiFi title has been awarded to Netherland invention, WaveLAN. Invented during 1991 by the NCR Corporation which later was renamed Lucent & Agere Systems, it held the chair of IEEE 802.11 for 10 years.

Bluetooth is capable also, like WiFi, of providing wireless internet to computers. This can be done by turning a data-capable mobile phone into a makeshift modem for dial-up internet access. The connection is then provided to the computer via Bluetooth which is wireless.

The difference between the two is that WiFi provides higher throughput and covers larger distances at the expense of having higher power consumption and requiring the installation of more expensive hardware. Bluetooth can be used to replace a variety of applications while the purpose of WiFi is just that, to provide wireless LAN access to devices designed capable of hosting it.

e)      Spaces where cable cannot be run, such as outdoor spaces, or where cables can most likely be damaged, can now host wireless LANS for people to enjoy connectivity.

f)      Local Area Networks can now be deployed to a mass number of users without the need for additional costs in network deployment and expansion.

g)       WiFi has set a global standard for wireless internet connectivity. Any WiFi capable device is fully capable of operating anywhere in the world.

h)       Dropping prices of WiFi chipsets allow it to be an economical networking option that can be integrated into other devices without drastically affecting overall price.    

The benefits of WiFi are:a)      Any WiFI capable device (eg. phone, MP3 player, PDA, game console, etc.) can tap into the Internet so long as they are within range of the wireless network.b)      WiFi is a great advertisement or promotion for enthusiasts or authorities who wish to promote a certain area. c)       WiFi has gathered together different vendors and unified them into a community. This has produced a unified front that branded products as WiFi capable to ensure consumers that devices are capable of inter-operating.d)      WiFi’s introduction into the business environment has decreased redundancy, enabled support for fast roaming, and increased overall productivity.

WiFi is a term derived from the phrase Wireless Fidelity. It is a popular wireless internet technology developed by the Wi-Fi Alliance and is supported by a majority of mobile phones, modern personal computers, and the latest game consoles.To describe WiFi entirely would take several long articles. Instead, here is a short list of the purpose Wi-Fi intends to fulfill.a)      WiFi is intended to easily enable access to information b)      WiFi was made for the purpose of ensuring compatibility and coexistence.c)       It was created to eliminate the need for cabling and wiring.d)      In the process, it also got rid the need for plugs, sockets, adaptors, switches, and connectors.
