Bluetooth technology is how mobile phones, computers, and personal digital assistants (PDAs), not to mention a broad selection of other devices, can be easily interconnected using a short-range wireless connection. Using this technology, users can have all mobile and fixed computer devices be totally coordinated.
Bluetooth wireless technology is a short-range communications technology
intended to replace the cables connecting portable and/or fixed devices while
maintaining high levels of security. The key features of Bluetooth
technology are robustness, low power, and low cost. The Bluetooth
specification defines a uniform structure for a wide range of devices to connect
and communicate with each other.
