BLUETOOTH TECHNOLOGY
ABSTRACT
Even though the age of wireless communications is upon us, many of us still deal with a plethora of cables that snake along and behind our desktop computers. Cables connect our printers, scanners, keyboards, digital cameras and any other peripherals that enhance our computing experience. If you have bluetooth technology integrated within your devices then wait no more.
Bluetooth technology enables computers, phones, handhelds, and peripherals to communicate with one another without cables. Bluetooth technology is not meant to replace wireless networks but to complement it. Bluetooth enabled devices give the user more flexibility, security, reduced power consumption, and becoming affordable for everyone bluetooth technology.
Bluetooth is a method for data communication that uses short-range radio links to replace cables between computers and their connected units. Ericsson showed wireless hands-free headset for its mobile phone. The headset used Bluetooth to connect to a special adapter attached to the cell phone.
Bluetooth technology is industry wireless specification standard for use in various devices for short-range communications. As a radio-based technology it allows devices to share information over a maximum range of 10 meters.
Bluetooth has been designed to operate in noisy radio frequency environments, and uses a fast acknowledgement and a frequency-hopping scheme to make the communications link robust, communication-wise. Bluetooth radio modules avoid interference from other signals by hopping to a new frequency after transmitting or receiving a packet.
