Abstract: Devices, systems, and techniques for a synchronized network for battery backup are described herein. A network device can establish a synchronized sleep schedule with the network while in a mains-power mode of operation. The network device can transmit data in the mains-power mode without regard for a transmission window of the synchronized sleep schedule. The network device can detect an interruption of mains power to itself and transition to a low-power mode of operation. The network device can then transmit data in the low-power mode, restricting data transmission to the transmission window of the synchronized sleep schedule.

Abstract: The physical position of a movable node in a network is determined by sending a first signal from a first reference node to at least a second reference node and the unknown node. The unknown node receives the first signal and sends a second signal to at least the second reference node in phase with the first signal. The first signal and the second signal are received in the second reference node and the phase of the received signals is compared to determine the position of the unknown node based on the phase difference between the received first and second signals.

Abstract: Systems and methods for the remote data exchange and device management with efficient file replication over heterogeneous communication transports. A user or application may provide a server with a communication bundle that may include a command and a data file. A transfer of the bundle from the server to one or more devices coupled to the server by a network over a first protocol may be initiated. Before the completion of the transfer, if a more cost effective connection becomes available the transfer of the bundle from the server to one or more devices may be completed via the more cost effective connection. The bundle may be transmitted in multiple segments. The individual segments may be transferred in any order and over various network protocols, and reassembled at the receiving device.
