Bluetooth is a wireless technology. Bluetooth is a short range communications technology from fixed mobile devices, creating personal area networks (PANs) with high levels of security. The features of Bluetooth technology low power and low cost. Created by telecoms vendor Ericsson in 1994, it was really conceived as a wireless alternative to RS-232 data cables. Today Bluetooth is managed by the Bluetooth Special Interest.
The structure and the global acceptance of Bluetooth technology means any Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices located in proximity to one another.
A fundamental capacity of Bluetooth wireless technology is capability to simultaneously transmissions of voice and data. which provides users with a variety of innovative solutions such as hands-free headsets for voice calls, printing and fax capabilities, and synchronization for PCs and mobile phones, just to name a few.
Blue Tooth Data Transfer Range
Range may vary depending on class of radio used in an implementation:
? Class 3 radios ? have a range of up to 1 meter or 3 feet
? Class 2 radios ? most commonly found in mobile devices ? have a range of 10 meters or 33 feet
? Class 1 radios ? used primarily in industrial use cases ? have a range of 100 meters or 300 feet.
? Wireless control of and communication between a mobile phone and a hands-free handset. Bluetooth was one of the earliest applications to become popular.
? Wireless networking between PCs in a confined space and where little bandwidth is required.
? Transfer of files, contact details, calendar appointments, and reminder between devices with OBEX.
? Wireless communication has PC input and output devices, the most common thing are mouse, keyboard and printer.
? For low band width applications where higher USB band width is not required
? Wireless bridge between two Industrial Ethernet
? Bluetooth technology is a first wireless technology transfer the data between the two devices like handsets.
