|Bluetooth is a wireless technology that uses radio frequency waves to transmit information. It is a relatively short-range wireless technology, with a range of about nine metres. Heydon (2008), a standards architect, states that Bluetooth is “lower-power, lower-cost and more robust”. The cost-efficiency of this technology makes Bluetooth a commonly used wireless technology globally.
According to Baig (2005), Bluetooth can even be complemented by wireless data transmission standards such as WiFi for greater range and throughput.
Bluetooth is commonly found in mobile phones and related peripheral today. Many phones allow file transfer between phones through Bluetooth, which eliminates the use of troublesome data cables. Many cell phones these days are also compatible with Bluetooth headsets, wireless headsets that allow users to talk in a phone conversation without holding the mobile handset near their ears. Since Bluetooth has a range of about nine metres, Bluetooth headsets allow users to pick up a call even if their cell phone is at an opposite corner of a room.
Bluetooth can also be used to send messages between phones, similar to those sent through the SMS service. This allows users of phones that are connected via a Bluetooth connection to communicate with one another without the use of the actual cellular network they subscribe to. This may seem to be not a very useful feature, but it has useful applications such as allowing persons on the same flight to communicate with one another even when there is no reception on flights.
Fenech (2007) highlighted a possibility of Bluetooth being used in cinemas to force Bluetooth-enabled cell phones into silent mode.
Imagine the endless possibilities with Bluetooth!
