Title: METHOD AND SYSTEM FOR SYNCHRONIZATION OF NODE DEVICES IN A COAXIAL NETWORK
Abstract:
Method for synchronization of a data communications network including a plurality of node devices (n0-n4) which are interconnected through a coaxial network and configured for data communication within a predetermined frequency bandwidth, comprising the steps of: transmitting a reference signal, at a frequency outside said bandwidth, from a first node device onto the coaxial network; receiving a loopback signal, at a frequency outside said bandwidth, from a further node device through the coaxial network; determining a time delay value (di,j) based on a time lapse (Ti,j) between transmitting the reference signal and receiving the loopback signal; sending the time delay value to said further node device.
