Abstract: The present invention relates to a method of establishing a connection between a mobile communicating object and a remote server, by way of a mobile communication network where the communicating object has a list encompassing a determined number of preferred mobile communication networks with which the object can be made to connect. The method comprises a first step where the communicating object establishes a radio connection with one of the networks available so as to transmit a first series of audit information (such as quality of signal, error rate, base station cell identifier) to the remote server, a step of verification by the server of the data received and, in the event of anomaly, of engagement of a procedure for modifying the selection of the mobile communication network to which the mobile object is connected.

Abstract: The present disclosure relates to a piece of electronic equipment for the replication of ports and the routing of digital signals, intended for secure environments for concentrating signals coming from a plurality of pieces of measuring equipment, as well as communication with a piece of supervising equipment. The equipment includes: —N ports whereof M ports are electrically insulated by optoelectronic coupler, N being an integer greater than or equal to 1, and M being an integer between N?1 and N, —a radiofrequency interface with a matched piece of supervising equipment, —a processor performing a protocol conversion between the radiofrequency protocol and the protocol of the ports.

Abstract: A presence tracking method includes the steps of detecting the presence of one or more agents in the vicinity of at least one predefined geolocated point by verifying the establishment of a short-distance communication between one or more mobile communication terminals of one or more agents with one or more fixed devices, associated and located at the predefined geolocated point, of informing one or more remote servers about the presence or not of agents in the vicinity of the predefined geolocated point by transmitting an acknowledgement signal to one or more remote servers at regular intervals; and, after the occurrence of one or more predetermined events, carrying out one or more operations in response to the event. The present disclosure also relates to a system for implementing the method.
