Wireless telemetering access
View Patent ↗Apparatus and a method for providing, to a service provider, telemetry access to customer equipment. The telemetry access is provided using wireless access means to avoid having to provide special residential wiring to connect to meters and control devices at customer premises. Each customer device is provided with a cellular station having its own mobile identity, either an international mobile switching identifier (IMSI) or a mobile identity number (MIN). Each IMSI or MIN need not be associated with a different telephone number. For example, a single telephone number can be assigned to a service provider to access all devices telemetered by that service provided. Advantageously, this arrangement provides for an inexpensive method and apparatus for accessing customer devices.
