Abstract: A method, apparatus, and system are described. The method includes generating a set of current values associated with at least one component included on a moving vehicle and providing the set of current values over a wireless network. The values are generated by one or more sensors. An edge computing device receives the current values. The method further includes processing the set of current values in real-time using at least one machine learning algorithm to identify a value of a point in time for a failure of one of the at least one component based on the set of current values and at least one set of past values received. The past values are stored in a memory. The set of current values are transmitted with a low time latency between the generating the set of current values and the processing of the set of current values.

Abstract: A hazard detector device comprises: a smoke detector to detect smoke, and to generate an output indicating that smoke is detected; a wireless receiver to receive, from a remote hazard detector apparatus, an incoming wireless communication signal indicating that the remote hazard detector apparatus detected a hazard; an audible alert generator to generate an audible alert in response to said incoming wireless communication signal; a wireless transmitter to transmit, to a remote alarm device, an outgoing wireless communication signal indicating that at least one of the following conditions exist: (a) the smoke detector of said hazard detector device detected smoke; (b) said hazard detector device received said incoming wireless communication signal indicating the remote hazard detector apparatus detected a hazard.

Abstract: Method and computer-readable medium for managing billing for calls within a user's telecommunications campus. According to the method and computer-readable medium for managing billing for calls within a user's campus, users can make unlimited calls within the campus by determining whether a call from a user begins in a predetermined area of use; determining whether the user is on a predetermined list of users, if the call began in the predetermined area of use; assigning a first billing rate to the call, if the predetermined list of users includes the user; and assigning a second billing rate to the call, if the predetermined list of users does not include the user.

Abstract: A method and system for private wireless network communications is provided. A private wireless network controller is coupled to a Private Branch Exchange (PBX), a private base transceiver station, and a Public Switched Telephone Network (PSTN). The private base transceiver station is coupled to a wireless macro network. The private wireless network controller and private base transceiver station allow connection of interconnect and dispatch wireless calls, which originate on the private wireless network, to other mobile stations on the private wireless network, to terminals connected to the PBX, to mobile stations on wireless macro networks, and to terminals coupled to the PSTN.
