Implementations disclosed describe numerous techniques and systems facilitating synchronous actions in wireless networks that have a central device (CD) and multiple peripheral devices (PDs) communicating wirelessly with the CD. The CD communicates one or more messages to the PDs and various PDs determine, using communicated messages, a time of a synchronous action to be performed by the PDs. The synchronous action includes an interaction of a respective PD with one or more associated devices communicatively coupled with the PD. Upon completion of the synchronous action, the PDs may transmit data generated by the PDs, or by the one or more associated devices, in connection with the synchronous action.

Time synchronization in wireless networks

A network interface is provided, in which it has an active mode and at least one of a disconnect mode and a suspend mode, and performs a predetermined process when a release condition of the disconnect mode or the suspend mode is satisfied. The network interface includes a driving control circuit for stopping at least a part of driving clock generation circuits included in the network interface until the release condition of the disconnect mode or the suspend mode is satisfied from the time when the disconnect mode or the suspend mode is established, wherein the driving control circuit operates irrespective of a clock signal.
