Techniques for clock synchronization over a wireless connection are provided. A first wireless node determines an offset between a first clock used by the first wireless node for a wired connection between the first wireless node and at least one upstream node and a second clock used by the first wireless node for a wireless connection between the first wireless node and a second wireless node on the downstream. The first wireless node transmits an indication of the determined offset to the second wireless node for use by the second wireless node to calibrate a third clock corresponding to the first clock to synchronize the third clock with the first clock, wherein the third clock is used by the second wireless node for a second wired connection with at least one downstream node.
