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.

A major concern of WiFi users is the vulnerability of encrypted data sent through WiFi. Studies have shown that the most common wireless encryption standard, the WEP or Wired Equivalent Privacy, was easily breakable even when configured correctly. WiFi networks are typically set to open mode, or encryption-free mode. These networks can be monitored and be used to read and copy any personal information that may be transmitted over the network unless more secure methods are use such as accessing secure web pages or VPN.To counter this problem, WiFi protected access have began shipping since 2003 and are now available in a majority of WiFi capable products.

As of now 300 plus cities all over the world now offer citywide free WiFi connectivity. St. Cloud, Florida was the first city to do so. Other cities included Luxembourg in Europe, Mexico City downtown, London, Liverpool, Manchester, Philadelphia, New Orleans, Corpus Christi in Texas, Leeds, Norwich and much more. An increasing trend in cities is that there are so many hotspots overlapping each other, anyone could get a good signal anywhere in the city. The popularity of integrating WiFi into districts has indirectly benefitted the city itself, especially if the city is only a small area, say Hong Kong for example.

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.
