Abstract: An infrastructure-controller for an infrastructure. The infrastructure-controller configured to: send a ranging-scheduling-signal to a key, wherein the ranging-scheduling-signal comprises timing-information for a subsequent ranging operation; and activate one or more ranging nodes associated with the infrastructure, for receiving a key-ranging-signal from the key, at an infrastructure-node-start-ranging-time based on the timing-information. The ranging-scheduling-signal has a frequency in a first RF frequency range. The key-ranging-signal has a frequency in a second RF frequency range.

Abstract: A controller for a communication and ranging apparatus wherein the apparatus is configured to transmit both a data signal and a ranging signal, wherein the controller is configured to: determine a scheduled transmission event of the data signal; determine a scheduled transmission event of the ranging signal; determine if the scheduled transmission events will occur within a predetermined time window of each other; if it is determined that the scheduled transmission events will occur within a predetermined time window of each other, then determine a priority signal and a secondary signal, wherein: the priority signal is one of the data signal and the ranging signal; and the secondary signal is the other of the data signal and the ranging signal; and provide signaling configured to prevent the scheduled transmission event of the secondary signal from being transmitted such that only the scheduled transmission event of the priority signal is transmitted.

Abstract: A first anchor of a first type communicates with a mobile electronic device. A characteristic of the communications between the first anchor of the first type and the mobile electronic device is determined. One or more second anchors each of a second type is selected based on the characteristic of the communications. A respective distance to the mobile electronic is determined based on each of the selected one or more second anchors each of the second type.

Abstract: An infrastructure-controller (206) for an infrastructure (202), wherein the infrastructure has a plurality of Bluetooth Low Energy, “BLE”, nodes (208, 210, 212) associated with it. The infrastructure-controller (206) is configured to: identify one of the plurality of BLE nodes as a current-BLE-node (212), and activate the current-BLE-node (212) for communication with a key (204) using BLE signals; determine a communication-quality-indicator for each of the plurality of BLE nodes (208, 210, 212), that represents the quality of communication with the key (204); based on the communication-quality-indicators, identify one of the plurality of BLE nodes as a next-BLE-node (210); and provide connection-information to the next-BLE-node (210) using out-of-band signalling (214). The infrastructure-controller (206) can then deactivate the current-BLE-node (212); and activate the next-BLE-node (212) for continued communication with the key (204) using BLE signals.
