Apparatus and method for synchronizing wireless devices

摘要

An apparatus for synchronizing devices includes a central access point node configured to utilize a low latency protocol to transmit a series of synchronization messages to the devices, transmit and receive data acquisition commands and responses from the devices using a high reliability protocol different from the low latency protocol, and calculate and apply relative clock offsets for each device based on the series of synchronization messages. The apparatus may also account for failure in delivery of a portion of the series of synchronization messages by recording timestamp data at the devices to send to the central access point prior to the central access point calculating the relative clock offsets.
