 Bluetooth
is an industrial specification for wireless personal area networks
(PANs). Bluetooth provides a way to connect and exchange information
between devices such as mobile phones, laptops, personal computers,
printers, GPS receivers, digital cameras, and video game consoles
over a secure, globally unlicensed short-range radio frequency.
The Bluetooth specifications are developed and licensed by the
Bluetooth Special Interest Group.
Bluetooth is a standard and communications protocol primarily
designed for low power consumption, with a short range (power-class-dependent:
1 meter, 10 meters, 100 meters) based on low-cost transceiver
microchips in each device.
Bluetooth enables these devices to communicate with each
other when they are in range. The devices use a radio communications
system, so they do not have to be in line of sight of each
other, and can even be in other rooms, as long as the received
transmission is powerful enough. |
