Abstract
A wireless sensing system and method for wireless sensor interrogation within a vehicle are disclosed. The wireless sensing system includes a plurality of radio frequency sensors distributed within a predefined area, a plurality of energizers within the predefined area for transmitting radio frequency signals to the plurality of radio frequency sensors, and at least one reader within the predefined area physically independent from the energizers for receiving radio frequency signals from the plurality of radio frequency sensors wherein the number of energizers exceeds the number of readers. The method for wireless sensor interrogation within a vehicle includes providing a plurality of radio frequency sensors distributed within the vehicle, providing a plurality of energizers and at least one reader within the vehicle wherein the number of readers is less than the number of energizers, transmitting radio frequency signals to the plurality of radio frequency sensors from the plurality of energizers, and receiving radio frequency signals from the plurality of radio frequency sensors with the at least one reader.
