| 摘要 |
The invention relates to a wireless network which includes a plurality of network nodes, each of which includes a radio device with a respective radio clock supply and is arranged to exchange data via a wireless medium, and also includes a user interface for the exchange of data between the associated radio device and at least one user. At least one user of a network node receives a user clock, being independent of the radio clock, from a user clock supply of the relevant network node. Each network node is arranged to determine, in response to events specified by a central network node, a time value related to the relevant application clock. The central network node transmits at least the last time value formed by a selected network node. Each network node forms the difference between the last two time values determined and synchronizes the frequency of its user clock supply in dependence on the comparison of the difference between its last two time values determined with the difference between the last two time values of the selected network node.
