Uses And Functions Of Bluetooth
Bluetooth is a fairly new function that is used to communicate between several devices securely and easily and has replaced many systems that previously utilized infrared technology. This technology exchanges data delivered on a short wavelength transmission by using open wireless technology
Bluetooth can be used on fixed and mobile devices to share information securely between several appointed appliances. These do not have to be able to visually see each other but do need to be able to travel on a wireless path and also require a significant level of antennae coverage.
Bluetooth works by generating a link key to connect machines which are then able to recognize each other and allow the transfer of data. Using this shared secret gives a higher degree of security as it is possible to delete any link at any time in order to cease any future exchanges and reduce external interferences or interception. Because of this unique method only pieces of equipment that recognize each other can provide permission for any transfer or receipt of information and this can be stopped at any time by either user.
To regulate the use and performance of this technology a Special Interest Group called the Bluetooth SIG was created by a number of companies within the technology and telecommunications field. If any company wishes to utilize the functionality then it must be agreed by and comply with the regulations set by the SIG.
Although it used throughout a wide range of sectors a major use is within the mobile phone industry who have used it to introduce features such as hands free calling and the personal exchange of music, photographs and videos between users and it is due to these features that it has almost become a standard within any handset.
This functionality is now found within personal computers with the increasing introduction of wireless hardware such as keyboards, mouse, speakers and printers and even digital cameras that can connect wirelessly to transfer images. A Bluetooth adapter has also been created so that those whose personal computer does not have the functionality built in can appreciate the benefits and this is usually in the shape of a data stick which is easily inserted and installed.
As well as personal use the functions of Bluetooth has also spread to be used within a wide variety of sectors and allows apparatus such as medical equipment and even traffic control systems to communicate with each other on demand.
