    Abstract: Provided are architectures, systems, methods, and computer program products for real-time object locating and position determination using frequency channel diversity for transmitting and receiving position determination signals including bursts of location signals. Channelized frequency diversity of a short burst of small location signals that “hop” across multiple frequency channels is used to collectively produce a quasi-wideband position determination signal. Object tags operating with frequency channel diversity for transmitting location signals of position determination signals require low power consumption, but can still efficiently provide adequate position determination signals for reliable position determination.

    Abstract: Systems, methods, apparatuses, and computer readable media are disclosed for providing timing-based distance measurement to a passive radio frequency identification (“RFID”) tag using one or more wideband RF signals synchronized with the standard narrowband RF signal. In some embodiments, the narrowband RF signal activates a passive RFID tag creating a backscatter reflection target which returns a modulated narrowband signal and a wideband signal from the passive RFID tag. The one or more wideband receivers determine time-of-flight and/or time-of-arrival measurements for the returned wideband signal. A location measurement is then calculated for the passive RFID tag using the tag data, the known location of the wideband transceivers, and the time-of-flight/time-of-arrival data.

    Abstract: A wireless local area network (WLAN) includes a server and receiver, which includes a radio frequency (RF) front-end circuit that receives wireless signals from the mobile nodes within the WLAN and detects baseband signals. A signal waveform detector edge detects a signal waveform and generates a trigger signal indicative of the modulation type, data format and time-of-arrival (TOA) information of a desired signal to be captured. A baseband processor receives the trigger signal from the signal waveform detector and captures the desired signal. A system controller is connected to the baseband processor and configures the baseband processor for processing the desired signal and obtaining message data and signal metrics that are transferred to the system controller to be communicated outbound from the receiver as a client to the server.

    Abstract: An example system for locating passive RFID tags includes a narrowband RFID reader configured to transmit a narrowband RF signal to energize a passive RFID tag, thereby causing the passive RFID tag to create a backscatter reflection target; a first wideband transceiver configured to transmit a wideband RF signal; a second wideband transceiver configured to: receive the wideband RF signal reflected from the backscatter reflection target; and record time-of-arrival data for the reflected wideband signal; and processing circuitry configured to determine a location measurement of the passive tag based on the time-of-arrival data.
