Bluetooth technology refers to the use of a wireless system of communication that uses a very short radio wave range. When it was first introduced to the electronics market, it was intended for realizing a more convenient and effective personal area network or PAN.  However, an increasing number of devices have been manufactured with this technology as an additional and important feature.

Still, it is most commonly used by PAN devices, such as wireless headsets for mobile phones, temporary connections between nearby computers, and PC to mobile connections.  The one thing that this technology solved is the hassle that cables and wires cause when connecting and disconnecting electronic devices.

While Bluetooth can allow only a very short distance for wireless connectivity, it can send signals powerful enough to carry a large amount of data at a single instance.  For a Class 1 Bluetooth device, the maximum range is approximately 100 meters and a permitted power of 100 milliWatt.  A Class 2 can have a maximum range of 10 meters at the power of 2.5 milli Watt. 

The weakest is Class 3 with range of only a meter at 1 milliWatt.  These signals no longer require any license from government telecommunication regulatory bodies because these operate along the ISM bands.  Industrial, scientific, and medical bands are free for use.  These range from 2.40 GHz to 2.48 GHZ.

At the limited range of frequency and the short transmission distance, the Bluetooth is definitely a very secure form of wireless communication.  There is essentially no danger in a transmission straying too far and finding its way to another person or network’s system.  It is able to hop over radio frequencies in a spectrum. The design of the technology requires authentication before data transmission can be completed. 

It also allows data encryption, making any information shared even more secure.  For this reason, this is used also by PC-to-peripheral and printer connections. Unlike other wireless devices that use radio frequency, there is hardly any interference felt during the whole time that Bluetooth signals are exchanged by two enabled mechanisms.

Ever since it came out as a secure means for data transfer, more communication and computer devices are being studied if these can be applied with Bluetooth technology too.  However, not only the telecommunication and IT industry have benefited from it. Automobile manufacturers have installed it in their electronic car lock systems.  Hospitals and clinics have found certain uses for it too. 

Currently, there is an increasing trend among hotels and airports favoring its use.  Instead of the usual intercom and hand-held radios, hotel staff and airport personnel can now be seen wearing headsets.  This provides management and employees a means to communicate easily among
