Abstract
A system and method for collecting, at a central station, utility consumption data from a plurality of sites, by a meter unit and a booster unit for each site. The meter unit includes a measuring device for measuring the utility consumption at the respective site; a storage device for storing the measured utility consumption during successive relatively-short time intervals; and a short-range transceiver. This booster unit includes a short-range transceiver for communication with the short-range transceiver of the meter unit at the respective site via a short-range transmission channel; and a long-range transmitter for transmitting utility consumption data to the central station via a long-range transmission channel. The system further includes a control system periodically activating the booster unit from a relatively long sleep state, to a relatively short active state during which the booster unit receives from its respective meter unit, via the short-range transmission channel, the utility consumption data stored therein during the preceding sleep state of the booster unit; and transmits the received utility consumption data to the central station via the long-range transmission channel.
