This is one of the tiniest miniaturised atomic clocks in the world. Atomic clocks are the most accurate time standards, regulated in correspondence with the vibrations of particular atomic or molecular systems. The future plan is to add atomic clocks in portable devices to improve synchronisation of communication networks, and increase transfer rates through high accuracy coordination between devices. Atomic clocks are useful in telecommunications for time multiplexing techniques. When transferring data from point A (e.g. a mobile phone) to point B (e.g. a base station of the cellular network), atomic clocks allow multiple users to transmit information packets on a single channel or frequency. This requires highly accurate synchronisation of emitters and receivers to identify time gaps between each of the signals. The more accurate the clock, the more data can be sent over a single channel.
