A communication system for transferring data from meter devices to a central monitor. The system uses personal communication devices such as cellular telephones and an existing cellular network to provide links between the remote sites. A recharge unit for a cellphone may be used to provide an interface between a cellphone and a meter. Electricity, gas and water meter information can be transferred from residential meters to the respective service providers, for example. Information may also be transferred from the service providers to the meters if required. |
