RFID for Indoor Position Determination

As Global Positioning System (GPS) behaves irrationally due to poor satellite reception, we provide an overview of indoor position detection of objects to precisely find out positions of different objects. Here we come up with Radio Frequency Identification (RFID) as an important tool for detecting objects that are occluded from satellite visibility. We briefly describe underlying architecture of RFID technology. We show how many innovations RFID technique have made by combining with Ultrasonic sensors, Infrared sensors, Impulse-Radio Ultra wide band, and image sensors that lead to different models. We also discuss these approaches in this position determination scheme as well as provide an overview of the pros and cons of each system. We also compare many existing systems and based on the underlying drawbacks, we propose a novel system design, architecture and illustrate its usefulness.
