A distributed radio geo-location and tracking system has a distributed subsystem architecture that distributes its processing workload over a plurality of information handling and processing subsystems. For maximum detection capability, each of a plurality of tag emission receivers is equipped with a circularly polarized, omnidirectional antenna, to provide hemispherical coverage. The receivers are coupled to a partitioned plurality of detection processors, that are coupled via distributed association processors to multiple location processors. Each detection processor demodulates and time stamps received energy correlated to known spreading codes of the tags, to associate received energy with only one tag. It transmits a message containing this information over a communication framework to an association processor. The computational load is equitably distributed by a flow control mechanism among available association processors, with all receptions of a single tag transmission being directed to the same association processor.

An object tracking system for locating radio-tagged objects within a monitored environment has a plurality tag transmission readers that detect RF transmissions from the tags, and generate output signals representative of the time-of-arrival of first-to-arrive tag transmissions. An object location processor processes the first to arrive signals in accordance with a multilateration algorithm to geolocate a tag. In order to modify the operation of a tag that comes within a prescribed region of the monitored environment (such as passing through a doorway), one or more relatively short range, magnetic field proximity-based, tag-programming ‘pingers’, are placed proximate to the region. A magnetic field receiver on the tag detects the field generated by the pinger and causes the tag to change operation such as increase its RF transmission rate.

A system and method controls entry or exit of a vehicle to or from a vehicle lot. A tag transmitter is adapted to be mounted on a vehicle for transmitting a wireless RF signal that includes vehicle data relating to the vehicle. A lane sensor is associated with a vehicle lane through which vehicles pass for at least one of entering and exiting the vehicle lot and is configured to receive wireless RF signals from the tag transmitter when the vehicle is in the vehicle lane, while substantially rejecting wireless RF signals from other tag transmitters mounted on other vehicles within the vehicle lot or in an adjacent vehicle lane. A processor is operatively connected to the lane sensor and receives and processes the vehicle data to validate and control the vehicle's entry or exit to or from the vehicle lot.

An object tracking system for locating radio-tagged objects has a plurality tag transmission readers that detect tag transmissions, and generate time-of-arrival output signals representative of the time-of-arrival of first-to-arrive tag transmissions on the basis of clock signals generated by local clock generators at the tag reader sites. The tag reader sites may transmit time-of-arrival signals to an object location processor by way of a wireless local area network. Measurements made on transmissions from a fixed position reference tag are used to update a reader clock offset database employed by the processor to maintain the reader clocks effectively time aligned.

A system of the present invention is operative for locating a wireless mobile device in communication with a wireless local area network (WLAN) that includes a plurality of cells defining a wireless local area network each having an access point base station. The access point base stations communicate with wireless mobile devices using wireless communication signals as typically spread spectrum communication signals. A processor is operatively connected to each of the access point base stations and operative to process communication signals transmitted from a mobile device and determine which signals are first-to-arrive signals based on a common timing signal and conduct differentiation of the first-to-arrive signals to locate the mobile device.
