Bluetooth is a form of technology that allows electronic devices to transmit and receive data wirelessly across short distances. This technology utilizes low-power, short-wavelength radio waves to establish a link between two or more devices that support Bluetooth. As a networking standard, it operates on two levels: physical and protocol. The physical level includes the radio frequencies, whereas the protocol level handles the accuracy and means of data transmission.Full Answer >
A Bluetooth dongle is an adapter used on non-Bluetooth enabled computers to connect wirelessly to a Bluetooth device. Most dongles plug into a USB port. A Bluetooth enabled computer has the adapter installed with the hardware inside the device, allowing the user to preserve USB ports for other uses.Full Answer >

Bluetooth works by transmitting data through radio waves that operate at a low power level and a specific frequency to create an uninterrupted connection between two devices. The frequency that Bluetooth operates falls between 2.402 and 2.480 gigahertz and has been reserved for industrial, scientific and medical device use internationally. To avoid causing interruptions with other devices operating in the same radio range, Bluetooth signals are emitted at one miliwatts.Full Answer >
