    摘要: A network of fixed RF transmitter modules, an RF repeater module and an RF collector module are located within a multi-unit facility for collecting water usage data from a plurality of water meters associated with the units within the facility and for uploading to a central billing center. Each water meter is coupled to a single RF transmitter module. Each RF transmitter module reads the water meter multiple times per day and transmits the data over a 418 MHZ carrier. One of a plurality of transceivers coupled to the RF repeater module receives the data and directs it to a storage medium in the RF repeater module. The RF repeater module temporarily holds the data and then repeats it on the RF carrier. The RF collector module receives the data through a transceiver coupled thereto. The data is stored in a storage medium of the RF collector module for retrieval by the central billing center.
