Abstract: A system for remote control of locomotives over a single time division multiple access network is provided. The system includes a locomotive control unit configured to operatively control a locomotive. The locomotive control unit is suitable for transmitting and receiving information via the network. The system also includes at least two operator control units suitable for transmitting and receiving information via the network and a hump control unit suitable for transmitting and receiving information via the network. The network employs both spatial and frequency diversity for remote control. The locomotive control unit, the at least two operator control units, and the hump control unit will only transmit in a respective defined period of time.

Abstract: Aspects of the invention provide for a mesh network management system. In one embodiment, a system is disclosed having: at least one computing device adapted to manage a wireless mesh network by performing the actions comprising: sending data including a plurality of fragments over a network to a plurality of Advanced Metering Infrastructure (AMI) nodes, wherein the data is sent a predetermined number of times; receiving, from the plurality of AMI nodes, a message regarding the plurality of fragments of the data; and sending, in response to receiving the message, fragments of the data that were not received by the plurality of AMI nodes.

Abstract: A communication system enabling wireless transmission of messages via packets; and a method of operating the system provides for improved accuracy in the transmission of a message, particularly for overcoming signal distortion associated with the phase changes and varying multipath found in transmissions from the locomotive of a moving train. The maximum benefit of forward-error correction (FEC) with Reed-Solomon (RS) coding is applied for a message payload that is significantly shorter than the fixed length of a packet, with lesser coding being performed with longer payloads.

Abstract: A system for managing element management in an ad-hoc network is disclosed. The system employs a TDD/FDD communication protocol to allocate assignment of time/frequency slots to individual system elements. Time/frequency assignment is based on desired communication standards in conjunction with geographic mapping of adjacent stations to prevent interference between stations.

Abstract: An advanced metering infrastructure (AMI) enabled device, program product and communication system. An AMI enabled device is described that includes a power failure detection system that constructs a power loss message in response to a detected loss of power and a communication system for transmitting messages over a network. The communications system includes: a prioritization system for prioritizing the power loss message as a high priority message, and a queuing system that ensures that the power loss message is transmitted ahead of all low priority messages.

Abstract: A mesh data network data management system where each of a plurality of nodes collects data when a respective triggering event occurs, puts the collected data in a reporting data packet, and sends the reporting data packet to an upstream node in the mesh data network. If a reporting node is in communication with a downstream node, it may also place received downstream data in the reporting data packet so that all data from a branch of the mesh data network in which the reporting node operates may be included in the reporting data packet.
