◆Use read enhancement technology: In environments that are greatly affected by metal and liquid, technologies such as directional antennas and enhanced readers can be used to improve the system's ability to penetrate and stabilize tags and reduce the number of tag misses.
◆Tag selection and customization: Selecting RFID tags that are suitable for specific environments is an important measure to reduce the problem of missed reading. Factors such as the absorbency of the material, the size and shape of the tag need to be considered. For scenes involving more metal or liquid, specially designed tags can be selected to improve readability.
◆Optimize tag layout: Reasonable layout of RFID tags is the key to reducing missed reading. Avoiding tags that are too close or overlapping can reduce the occurrence of collisions. In addition, the placement and orientation of the tag also affect the reading performance. Therefore, when arranging, ensure that the tag is in the best reading position and orientation to improve the successful reading rate.
◆Antenna design and deployment: The design and deployment of antennas are crucial to RFID reading performance. The use of appropriate antenna design and optimized deployment strategies can reduce the impact of multipath effects and obstacles such as metal and liquid on RFID signals. By adjusting the direction and angle of the antenna, the reflection and attenuation of the signal can be minimized, and the reader's ability to accurately read the tag can be improved.
◆Optimize spectrum management: The RFID system works in the wireless spectrum and is easily interfered by signals from other electronic devices. By rationally planning and managing the spectrum used by the RFID system, selecting unoccupied frequency bands or using spectrum hopping technology, the impact of signal interference can be reduced and the success rate of RFID tag reading can be improved.
