Abstract: A capability for localization of a wireless tag based on wireless gateway association information uses a wireless tag supporting multiple states and wireless gateway association information associated with the wireless tag to control localization of the wireless tag. The wireless tag may support an unconnected state in which the wireless tag communicates location tracking information using a wireless beacon signal which may be detected by various wireless gateways and a connected state in which the wireless tag communicates location tracking information via one or more connections with one or more wireless gateways. The wireless gateway association information may include wireless gateway lists (e.g., whitelists, blacklists, or the like), association rules, notification rules, or the like. The wireless gateway association information may be used to control transitions of the wireless tag between the unconnected state and the connected state, to control notifications for the wireless tag, or the like.

Abstract: A capability for flexible communications within an energy-limited wireless system is presented. An energy-limited wireless node includes a communication module configured to switch between a sleep mode in which the communication module is not operable to communicate and an active mode in which the communication module is operable to communicate, a configurable auxiliary receiver configured to initiate switching of the communication module from the sleep mode to the active mode based on detection of a wake-up signal, and a controller configured to control configuration of the configurable auxiliary receiver to operate using an auxiliary receiver configuration.

Abstract: There is provided a communications network comprising a network node and a resource limited node. The network node comprises a controller operable to estimate an optimal duty cycle for various operating modes of the resource limited node to minimize the overall resource consumption of the resource limited node; and a transmitter operable to notify parameters of the estimated optimal duty cycle to the resource limited node.

Abstract: A femto cell device comprises: a receiver for receiving transmissions from a user terminal in an active call with a macro cellular network node; an analyzer for determining a radio frequency (RF) signature characterizing the transmissions received from the user terminal; an authorizer arranged to use the RF signature to determine if the user terminal is authorized to use the femto cell device; and a communicator for informing the core network that the femto cell device is a valid candidate handover target for the user terminal when the user terminal is determined by the authorizer to be authorized to use the femto cell device.

Abstract: A capability for controlling or facilitating the use of a wireless tag to communicate location tracking information is presented. The capability for controlling or facilitating use of a wireless tag to communicate location tracking information utilizes a wireless tag supporting multiple states in order to control communication of location tracking information. The wireless tag supporting multiple states in order to control communication of location tracking information may be configured to support or facilitate tag-controlled state transitions, gateway-controlled state transitions, infrastructure-controlled state transitions, or the like, as well as various combinations thereof.

Abstract: Various embodiments provide a method and apparatus for determining tag location by using one or more estimated channel responses (CR) that characterize the wireless channel between the tag and one or more respective anchors. In particular, a tracking server in communication with the anchor(s) determines the tag's location based on a comparison of the estimated CR(s) with a set of stored CRs associated with the anchor(s).
