A vehicle tracking system includes a wheel assembly containing sensor circuitry capable of sensing various types of conditions, such as specific electromagnetic and/or magnetic signals indicative of particular wheel locations. The sensor circuitry is coupled to an RF transceiver, which may but need not be included within the wheel. The wheel may also include a brake mechanism. In one embodiment, the wheels are placed on shopping carts and are used to collect and monitor shopping cart status and location data via a wireless network. In some embodiments, the wheel assemblies detect that they have entered into particular zones by measuring received signal strengths of received command transmissions, and by comparing these measurements to thresholds that are used to define zone boundaries.
