摘要： A technique of reducing the interference wave occurred between a plurality of reader/writers in an environment in which a plurality of RFID systems are operating. An RFID system includes a plurality of reader/writers and a controller for controlling the plurality of reader/writers. Each reader/writer includes a body, antennas, and a distributor for selecting one antenna from the antennas. The controller selects an antenna having a positional relationship in which the interference wave is small from the antennas of each reader/writer, and giving a command for the antenna to the body of each reader/writer. Each reader/writer selects one antenna from the antennas based on the command from the controller and transmits a command to the RFID.

摘要： A technology for detecting an RFID by a reader writer and transmitting harmonics for reading and writing the RFID timely without using an object detection sensor is provided. Using a nonlinearity of a rectifier or a demodulator in an IC chip of the RFID, a continuous wave or a modulated wave of two or more different frequencies is output from the reader writer. The RFID receives the continuous wave or the modulated wave of two or more different frequencies and the reader writer receives harmonics intermodulation generated by the rectifier or the demodulator in the IC chip. Therefore, the RFID can be detected without any special object detection sensor, and a modulated wave for reading or writing the RFID can be transmitted.

摘要： A reader/writer (R/W) transmits a query command ALL (A), which causes RFID tags (A) with a communication method (A) to respond at a time, to N RFID tags (A) with the communication method (A) and X RFID tags (C) with a communication method (C). In this case, since R/W receives responses from N RFID tags (A), it can recognize presence of the RFID tags with a communication method (A) from its reception level or the like. Next, R/W transmits a query command ALL (B) which causes RFID tags (B) with a communication method (B) to respond at a time. In this case, since R/W receives no response, it can recognize that no RFID tag with the communication method (B) is present rapidly. In an RFID system, therefore, a communication time between RFID tags and an RFID reader/writer can be reduced.
摘要翻译：读取器/写入器（R / W）通过通信方法（N）向N个RFID标签（A）发送一个使得通信方法（A）的RFID标签（A）一次响应的查询命令ALL（A） A）和X RFID标签（C），具有通信方法（C）。在这种情况下，由于R / W接收到来自N个RFID标签（A）的响应，因此可以从其接收等级等利用通信方法（A）来识别RFID标签的存在。接下来，R / W以通信方式（B）发送使得RFID标签（B）一次响应的查询命令ALL（B）。在这种情况下，由于R / W没有收到响应，因此可以认识到没有快速存在具有通信方式（B）的RFID标签。因此，在RFID系统中，可以减少RFID标签与RFID读写器之间的通信时间。

摘要： A plurality of masters continuously receives data through a specific channel to detect whether a slave exists nearby. On the other hand, the slave transmits data for a given period through the specific channel by a trigger specified by a user. A master near the slave receives the data transmitted by the slave and recognizes that the slave exists nearby. After the recognition of the slave, the master performs carrier senses on channels other than the specific channel and transmits data for a given period through a channel on which a carrier does not exist. After the transmission through the specific channel, the slave receives a plurality of channels other than the specific channel to receive the data transmitted by the master.
