Bluetooth

Bluetooth allows wireless personal networks to connect and exchange information among devices such as mobile phones, laptops, printers, and digital cameras over a secure short-range radio frequency (Johnson, 2006). Bluetooth works when two or more devices are in proximity (100 meters or less) to one another and do not require high bandwidth. Other than the device, there is no cost for using Bluetooth technology. Bluetooth technology has been incorporated into classrooms as a secure communication between teacher and student or administrator. Educators can transfer data and image files wirelessly among devices like laptops, mobile phones, PDAs, whiteboards, and printers. When designing a wireless network or selecting peripherals, Bluetooth applications should be considered. More information on the specifications and applications is available at [|www.bluetooth.com].
