A: Signal degradation in RFID systems can be caused by several factors, including the presence of metal objects, water or other liquids, and interference from other RFID tags or electronic devices. The physical distance between the RFID reader and tag also plays a significant role in signal quality. How does physical distance affect the signal in RFID systems? A: Physical distance is a critical factor in determining signal quality in RFID systems. As the distance between the RFID reader and the tag increases, the signal strength decreases, which can lead to signal degradation or complete loss of communication between the reader and the tag. This is due to the inverse square law, which states that the signal intensity diminishes with the square of the distance. As a result, ensuring an optimal reading distance is crucial for reliable RFID system performance. - 免费预告片中文字幕 srt。
