数据传输速率的考虑 载波频率和频带宽度与数据传输速率密切相关。一般讲,载波频率越高,可实现的数据传输率越高。通信过程所占用的频带越宽,数据传输速率也越高。定性地讲,阅读器与标签之间通信所需要的频带宽度应该是数据率的两倍。在窄带通信的条件下,RFID系 Data transmission rate considerations Carrier frequency and bandwidth are closely related to data rates. In general, the higher the carrier frequency, the higher the data transfer rate that can be achieved. The wider the frequency band occupied by the communication process, the higher the data transmission rate. Qualitatively, the bandwidth required for communication between the reader and the tag should be twice the data rate. Under the condition of narrowband communication, RFID system
