Answer: The positioning accuracy of the 433MHz network in an open area is 3 to 5 meters, and the positioning in the cell is room-level positioning. In addition, the 433MHz network has better diffraction performance and less interference to occlusion.
Answer: UWB positioning accuracy is high, positioning accuracy is centimeter level, about 30cm.
Answer: The RFID location service system uses LF low frequency activation and UHF (ultra high frequency / low frequency) RSSI (field strength value) positioning technology. Based on this, Rongfei ’s unique ROFREV Anti-collsion location protocol The addition of Stack V2.0 can meet the requirements of large capacity (ten thousand people), high reliability (100% accuracy) and anti-interference in the judicial industry, and realize the location service of all personnel and vehicles in the institution.
