APPARATUS AND RELATED METHOD FOR DATA SYNCHRONIZATION ACROSS A W IRELESS NETWORK

摘要

The present invention provides for a transmitting means for transmitting data packets in a wireless network, wherein at least some of the data packets are arranged to include clock data for use at a receiving means in the network for clock reconstruction at the receiving means, the transmitting means including processing means and operating system means connected to a network controller for delivering the data packets to the network, wherein the transmitting means is arranged to identify packets arriving at the network controller and which require clock data, and wherein the network controller is arranged to insert the clock data within the said identified packet prior to transmission of the packet. Also provided is a system and method of synchronising the clock of a receiving means to a clock signal from a transmitting means in a wireless network, wherein the clock at the receiving means is reconstructed from a data packet delivered from the transmitting means and including the step of monitoring acknowledgement of receipt of the packet at the receiving means, and resending the said packet if receipt is not acknowledged, and including the step of inserting updated clock reference data in the packet prior to resending the packet.
