SYSTEM AND METHOD FOR DETERMINING THE ENTRY OR EXIT LANE OF VEHICLES PASSING INTO OR FROM A VEHICLE LOT USING TAG INTERROGATOR AND RSSI
First Claim
1. A system for determining the entry or exit lane of vehicles passing through a vehicle gate, comprising:
- a vehicle gate comprising a plurality of vehicle lanes through which vehicles enter or exit;
a tag interrogator positioned at a predetermined location of the vehicle gate for emitting a signal containing a tag interrogator ID identifying the tag interrogator such that a plurality of vehicle lanes are within range to receive the signal; and
a tag transmitter mounted on a vehicle that enters or exits a vehicle lane and receives the signal emitted from the tag interrogator, wherein said tag transmitter is operative for determining the received signal strength indication (RSSI) and in response to receiving the signal, transmitting an RF signal containing the tag interrogator ID and the RSSI for determining which vehicle lane the vehicle is located based on the tag interrogator ID and RSSI.

Abstract
A system determines the entry or exit lane of vehicles passing through a vehicle gate that has a plurality of vehicle lanes through which vehicles enter or exit. A tag interrogator is positioned at a predetermined location of the vehicle gate and emits a signal containing a tag interrogator ID. A plurality of the vehicles lanes are within range to receive that signal. A tag transmitter is mounted on a vehicle that enters or exits the gate and receives the signal emitted from the tag interrogator, which determines the Received Signal Strength Indication (RSSI) and in response, transmits an RE signal containing the tag interrogator ID and the RSSI for determining which vehicle lane the vehicle is located based on the tag interrogator ID and RSSI.

9. A system for determining the entry or exit lane of vehicles passing through a vehicle gate, comprising:
-
a vehicle gate comprising a plurality of vehicle lanes through which vehicles enter or exit; a tag interrogator positioned at a predetermined location of the vehicle gate for emitting a signal containing a tag interrogator ID identifying the tag interrogator such that a plurality of vehicle lanes are within range to receive the signal; a tag transmitter mounted on a vehicle that enters or exits a vehicle lane and receives the signal emitted from the tag interrogator, wherein said tag transmitter is operative for determining the received signal strength indication (RSSI) and in response to receiving the signal, transmitting an RF signal containing the tag interrogator ID and the RSSI; at least one access point positioned at a known location that receives the RF signal from the tag transmitter; and a processor operatively connected to said at least one access point for receiving and processing the data received from the tag transmitter and determining which vehicle lane the vehicle is in based on the tag interrogator ID and RSSI of the signal received from the tag interrogator. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for determining the entry or exit lane of vehicles passing through a vehicle gate, comprising:
-
providing a vehicle gate comprising a plurality of vehicle lanes through which vehicles enter or exit; emitting a signal containing a tag interrogator ID from a tag interrogator positioned at a predetermined location of the vehicle gate that identifies the tag interrogator, wherein the plurality of vehicle lanes are within range of the signal at the vehicle gate and receive the signal; receiving the emitted signal from the tag interrogator within a tag transmitter mounted on a vehicle that enters or exits one of the vehicle lanes in proximity to the signal emitted from the tag interrogator and determining the received signal strength indication (RSSI) and in response to the signal received from the tag interrogator, transmitting an RF signal containing the tag interrogator ID and the RSSI of the signal emitted from the tag interrogator to determine which vehicle lane the vehicle is located based on the tag interrogator ID and RSSI. - View Dependent Claims (22, 23, 24, 25)
