摘要： Methods and systems for determining a device position include determining (704) a first position estimate using radio-based range information. A second position estimate is determined (708) using visual odometry information. The first position estimate and the second position estimate are fused (710) based on radio environmental conditions and visual environmental conditions to determine a final position estimate. Resources are deployed (606) based on the final position estimate.

摘要： A computer-implemented method for dynamic provisioning of Wi-Fi capacity in areas using a centralized radio access network (C-RAN) architecture is presented. The computer-implemented method includes introducing a set of access points (APs) in a network for providing capacity required to serve a plurality of users accessing heterogeneous content, introducing a set of remote radio heads (RRHs) in the network acting as transmit/receive points, tracking traffic fluctuations, and adapting front-haul configurations at a granularity of epochs, where measurements from previous epochs serve as input to drive current epochs.

摘要： Methods and systems for localization within an environment include determining (2402) a topology estimate of nodes located in a dynamic indoor environment, based on distances measured between the nodes. Rigid k-core sub-graphs of the topology estimate are generated (2404) to determine relative localizations of the nodes. Relative localizations are transformed (2406) into absolute localizations to generate a map of positions of the nodes within the environment. A feature of the map is deployed (2410) to a device in the environment.

摘要： Aspects of the present disclosure describe a battery-free touch sensing user interface (UI) for Internet of Things (IoT) and other smart spaces employing Radio Frequency Identification (RFID) readers and tags that we call RIO. With RIO, any surface may be a touch-aware surface by attaching RFID tag(s) thereto. RIO advantageously supports custom-designed RFID tags and therefore facilitates customized UIs to be easily deployed in a real-world environment. RIO employs impedance tracking that results from a human finger - or other appendage - touching a surface of an RFID tag, thereby changing a characteristic impedance of the RFID tag antenna. This change manifests as a change in the phase of the RFID backscattered signal and is advantageously used by RIO to track fine-grained touch movement over the RFID tag. Disclosed further are multi-tag environments in which RIO operates and demonstrations including continuous tracking of finger movement during a swipe to within 3mm of its actual position.

摘要： A product locating system is provided. The system includes at least one Radio Frequency (RF) backscatter transmitter (410) configured to emit a main carrier RF signal that forms an excitation signal. The system further includes a passive RF backscatter tag (420) associated with a product and configured to generate an Ultra-Wideband (UWB) signal from the excitation signal. The system also includes at least one RF backscatter receiver (430) configured to simultaneously receive both the excitation signal from the at least one RF backscatter transmitter and the UWB signal from the passive RF backscatter tag, and compute the time-difference-of-arrival (TDoA) therebetween. TDoA information from multiple RF backscatter receivers, including the at least one RF backscatter receiver, is aggregated to compute the location of the product to which the passive RF backscatter tag is attached.
