Researchers at Missouri University of Science and Technology say they have developed a new technology that increases read rates, reduces read errors, and improves system coverage in RFID systems used in a variety of applications. According to the scientists, the patent-pending technology helps eliminate RFID signal collision by employing two different schemes to adjust RFID reader power in response to interference levels.
The technology uses distributed adaptive power control and probabilistic power control schemes to adjust RFID reader power output in response to signal collision, the interference which occurs when multiple RFID readers try to read RFID tags or when RFID antennae are in close proximity to each other. The new technique was developed by a research team led by Dr. Jagannathan Sarangapani.
Missouri University of Science and Technology, formerly known as the University of Missouri-Rolla, is a part of the University of Missouri system. The school’s Office of Technology Transfer and Economic Development, which serves as the focal point for entrepreneurship, economic development, technology transfer, and technology commercialization, is currently looking for a commercial partner to bring the technology to market.
