Abstract: Some embodiments include an apparatus, method, and computer program product for high precision device synchronization of electronic devices in a shared medium. Some embodiments include a first electronic device that utilizes a combination of synchronization techniques to synchronize with a second electronic device. The first electronic device receives a first signal from the second electronic device that includes network-based synchronization data and marker data, and performs network-based synchronization with the second electronic device at a first synchronization accuracy. The first electronic device receives a second signal, and uses the marker data and phase lock synchronization to detect a frequency change of the second signal received, as well as to determine a corresponding time marker. The first electronic device updates a clock of the first electronic device based at least on the corresponding time marker, the network-based synchronization data, and the marker data.
