Bluetooth networks connect devices wirelessly by using short-range radio frequencies to establish a connection. Depending on the Bluetooth device, the range can extend up to 100 meters (~328 feet). You can secure a Bluetooth connection by using a secure Personal Identification Number (PIN) between two devices.
Bluetooth is primarily used with cell phones, telephone headsets, handheld devices, mice, keyboards and mobile printers, and is also a strong choice for retail business peripherals such as point of sale (POS) systems
Bluetooth-enabled notebooks can interact with other Bluetooth-enabled phones, handhelds, notebooks and more, all without wires. It's a good idea to make sure that your new notebooks have integrated Bluetooth capability, even if you're not sure you can use it right now. Bluetooth devices can go a long way toward letting you customize your mobile experience now and in the future.
