Systems and methods for updating firmware or other critical configuration data in scalable distributed systems are provided. Such systems and methods can include (1) a master controller receiving (a) a firmware update file that is divided into a plurality of packets and (b) a metadata file that is associated with the firmware update file and (2) a first one of a plurality of slave controllers receiving the metadata file and, responsive thereto, updating a local peer table to include entries for the master controller and a group of the plurality of slave controllers that are available to share any of the plurality of packets and downloading each of the plurality of packets from a combination of the master controller and the group of the plurality of slave controllers.

Systems and methods for updating firmware and critical configuration data to scalable distributed systems using a peer to peer protocol

A location tracking system includes a first plurality of signal receiving and transmitting devices, the members of the first plurality each include an RF transceiver, sound receivers and sound emitters. A second plurality of signal transmitting units, the members of the second plurality each include at least an RF transceiver and a sound emitter. A system control element in communication with the members of the first plurality wherein the control element determines the locations of members of the second plurality based, at least in part, on information received from members of the first plurality.
