摘要： A radio communications network for transmitting data from a plurality of remote stations to a central station is provided. This system is particularly proposed for automatic meter reading systems in which the remote stations are located at utility meters. The system includes an array of receiving stations arranged relative to the remote stations so that the messages from each remote station can be received by at least two and preferably four of the receiving stations providing a high level of duplication of messages. The remote stations transmit utility usage information obtained from a previous time period at a random time subsequent to the time period so that message collisions can occur. High level of duplication provided by the increased number of receiving stations reduces the message loss. A quiet period during which the remote stations are prevented from transmitting can be used for communication between the receiving stations and the central station.

摘要： A wide area communications network communicating data from a plurality of network service modules through a plurality of remote cell nodes and intermediate data terminals to a central data terminal. The wide area communicates network collects network generated by a plurality of physical devices such as gas, water or electricity meters, located within a geographical area. The wide area communications network is a layered network have a hierarchical communications topology. The central data terminal controls network operation. Intelligence exists at all layers of the network, thereby easing the workload of the central data terminal. The intelligence attributed to each module is a function of the application of that module.
