Abstract
In a method of controlling a frequency via an asynchronous transmission network, signals received at the output of the asynchronous transmission network have been clocked at a reference frequency and transmitted by the network with respective varying transit delays and the frequency of a local clock is slaved to the reference frequency by means of an error signal formed from selected received signals with minimal transit delays. Applications include local mobile telephone networks.
