Bluetooth is a short-range radio technology aimed at simplifying communications among Internet devices and between devices and the Internet. It is a computing and telecommunications industry specification that describes how mobile phones, computers and personal digital assistants can easily interconnect with each other and with home and business phones and computers using a short-range wireless connection. Using this technology, users of cellular phones, pagers, and personal digital assistants will be able to buy a three-in-one phone. You can make it possible to use this phone as a portable phone at home or in the office, get quickly synchronized with information in a desktop or notebook computer, initiate the sending or receiving of a fax, initiate the sending or receiving of a fax, initiate a print-out. So basically you can have all mobile and fixed devices totally coordinated, thanks to Bluetooth technology. Fundamentals of Bluetooth Bluetooth is a standard developed by a group of electronics manufacturers that makes it possible for cell phone to make its own connections, without wires, cables or any direct action from a user using Bluetooth enabled phone. It is not just with cell phones even computers and more electronic devices can make their own connection using Bluetooth. Bluetooth is designed to be a standard that has two levels of working: 1] Bluetooth is a radio-frequency standard. It provides agreement at the physical level. 2] It also provides confirmation at the next level of communication, where products have to agree on when bits are sent, how many will be sent at a time and how the users in a conversation can be sure that there is no adulteration in the message received after it has been sent. There are more than 1,000 companies belonging to the Bluetooth Special Interest Group. Bluetooth communication has taken the place of wires for connecting peripherals, telephones and computers. This technology is very popular among the cell phone users. It has given the cell phone technology new heights and is proving its worth as time passes. There are many advantages to cell phone users for using Bluetooth technology: 1] Bluetooth does not require you to do anything special to make it work. The devices find one another and strike up a conversation without any user input at all. It will make your work very easy once you use it for establishing connection. 2] It is wireless. When you travel, you do not have to worry about any type of wires or arranging hands free connected to your cell phone. They are no more required. 3] It is cost effective. It is not all that expensive as compared to the work it can do for you and it will make communication through cell phone a pleasure. Bluetooth has overcome the limitation of infrared about the distance and reliability. As compared to infrared, Bluetooth can make communication possible over longer distances and Bluetooth is more reliable also. Products with Bluetooth technology must be qualified and pass interoperability testing by the Bluetooth Special Interest Group prior to release.
