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.

Proximity-based localization of wireless tags based on wireless gateway association information

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. A controller includes a processor and a memory communicatively connected to the processor wherein the processor is configured to determine a configuration for a configurable auxiliary communication module of an energy-limited wireless node, and propagate, toward the energy-limited wireless node, an indication of the configuration for the configurable auxiliary communication module of the energy-limited wireless node.

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. The multiple states of the wireless tag may specify use of different sets of wireless gateways for communication of location tracking information, use of different protocols for communication of location tracking information, use of different air interfaces for communication of location tracking information, use of different performance parameters for communication of location tracking information, or the like.

A capability for opportunistic forwarding of information using a wireless terminal is presented. An energy limited node includes a wake-up circuit configured to detect a wake-up signal from a wireless terminal where the wake-up signal includes a modulated waveform signal, and a communication module configured to switch, based on a control signal generated by the wake-up circuit, from a sleep mode in which the communication module is not operable to communicate with the wireless terminal to an active mode in which the communication module is operable to communicate with the wireless terminal. A wireless terminal includes a first wireless communication interface configured for communication with a device using a wireless communication protocol, a second wireless communication interface configured for wireless communication with a wireless access node of a wireless network, and a processor configured to support opportunistic forwarding of information between the device and the wireless access node of the wireless network.

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).

Method and apparatus for determining tag location

A method is provided of radio communication in a radio communications network comprising a macrocell base station and a femtocell base station. The method comprises the femtocell base station: transmitting in a first radio frequency band that is allocated to the macrocell, and detecting that a user terminal that is connected to the macrocell base station is in the femtocell. In response to said detecting the user terminal as being in the femtocell, the femtocell base station ceases to use that frequency band at least in the region in which the user terminal is located so as to avoid unacceptable interference to the user terminal.
