Abstract
A communication system is provided for communication between network nodes and a communication controller. In the network, a request signal is transmitted from a first node to the communication controller when the first node has a packet data message to transmit. The communication controller then acknowledges the request, and the first node transmits its data message in response. The communication controller further transmits a clocking signal allowing synchronization of the node signals with the controller signals. The clocking signal, request, acknowledgement and data message can all be provided on different frequencies, allowing simultaneous transmission of these signals for efficient operation.
