Instead of using wires and cables to connect two devices, Bluetooth devices can connect with each other using radio waves . In order for Bluetooth devices to work, you must connect the hardware and software. The equipment usually consists of mikroczipa with internal antenna. This system can transmit and receive signals at specific frequencies. The software is then used to interpret the incoming call or signal that can be read other devices with Bluetooth connectivity.

To ensure no interference when communicating with Bluetooth devices perevarivat they are 1600 frequency hops per second. When two devices are synchronized, they perevarivat synchronously. This frequent change in wavelength means that if the signal is interrupted due to some unexpected, not interrupted longer than 1/1600 of a second.
