Generally, the present invention automatically monitors the travel of vehicles in response to requests from users at remote locations. In this regard, a user at a remote location submits a vehicle indicator (such as a bus number, for example) and a location indicator (such as a bus stop number, for example) to a data manager at a vehicle tracking system. The data manager automatically retrieves travel data and location data based on the vehicle indicator and the location indicator. The travel data indicates the current location of the vehicle identified by the vehicle value, and the location data represents a location along the vehicle's route of travel. The data manager then compares the travel data and the location data in order to determine whether the vehicle is a predetermined proximity from the location represented by the location data. When the vehicle is a predetermined proximity from the location identified by the location data (i.e., arrival of the vehicle at the location is imminent), the data manager automatically transmits a notification message to the user at the remote location.

A method and system enhances the gain of a propagation path of a radio frequency (RF) signal while utilizing an envelope tracking (ET) mechanism to provide power to a power amplifier within the propagation path. An envelope tracking (ET) controller detects using the ET mechanism an RF envelope of the RF signal being propagated towards the power amplifier. The ET controller applies envelope pre-distortion to the RF signal. The ET controller initiates a function for shaping the supply voltage of the power amplifier by selecting a shaping table that can provide a specific level of increasing amplifier gain at higher signal drive level. The ET controller shapes the supply voltage for the power amplifier by adjusting values corresponding to the detected RF envelope. As a result, RF signals are propagated from the transceiver to the power amplifier output port across high and low transceiver drive levels with net constant gain.

The invention disclosed in this document is a vehicle tracking system using Radio Frequency Identification (RFID) transponders and an RFID transceiver, which is attached to a moving vehicle to collect vehicle location data. Each location code is encoded on a transponder, which is then embedded at a location along a vehicle's route to be read by the transceiver as the vehicle passes nearby. The data read by the transceiver is transmitted to the Internet using a mobile communication device like a cell phone. By having fixed transponder locations and a transceiver that is on the moving vehicle, this system becomes the reverse of the typical RFID item-tracking system. In addition, it is able to use the data stored on the RFID transponders, read by the RFID transceivers, and processed by the data storage and processing device to determine whether a vehicle is on its predetermined route, estimate when the vehicle will arrive at future stops on its scheduled route, and determine whether it is on schedule. This RFID vehicle-tracking system is therefore unique.
