Abstract
A cellular network data transmission system including a digital communicator having a memory in which data is stored and an automatic dialer at a specific location for responding to an electrical signal indicating a specific condition exists, a cellular interface connected to the digital communicator and a cellular transceiver having an antenna, connected to the cellular interface, a cellular network including a central computer and an antenna for receiving signals from the transceiver antenna and for transmitting such signals from the central cellular computer site to a central monitoring station whereby the occurrence of a specific condition at the specific location initiates the dialing of an assigned number by the automatic dialer and the transmission of data corresponding to the specific location from the memory through the interface, transceiver and cellular network to the central monitoring station, the cellular network also adapted to receive signals initiated by the central monitoring station and to transmit such signals from the central cellular computer site to the transceiver antenna, whereby such signals are sent through the cellular network, transceiver and interface …
