Abstract:
A wireless network, comprising:a plurality of network nodes arranged to exchange data via a wireless medium, each of said nodes including, at least one electrical apparatus, and at least one radio device, wherein each network node includes a clock supply for supplying said electrical apparatus and the radio device with its clock, wherein a network node which is designated as a main network node is arranged to transmit, via its radio device, a synchronization pattern which is dependent on the clock of its clock supply, wherein all other network nodes, designated as secondary network nodes, are assigned to different, hierarchically ordered distance classes in dependence on their distance from the main network node which is assigned to the highest distance class, wherein all secondary network nodes of a distance class are arranged to transmit, via their respective radio device, a synchronization pattern which is dependent on the clock of their respective clock supply and characterizes the distance class, and wherein a secondary network node is arranged to synchronize its clock supply by means of at least one received synchronization pattern of a hierarchically higher distance class.
