  • Publication number: 20210266770
    Abstract: A system includes a plurality of readers and an information processor. The reader includes a first communicator, an antenna, and a first processor. An antenna communicates with radio tags. The first processor measures a time in which radio waves are received with a plurality of channels in a carrier sense time, the carrier sense time being a time in which the radio tags are not communicating and transmits a channel report indicating a time in which radio waves are received with each channel to the information processor through the first communicator. The information processor includes a second communicator and a second processor. The second processor acquires the channel report through the second communicator and generates an aggregate report indicating channel states while the plurality of readers are not communicating with the radio tags based on the plurality of acquired channel reports.

  • Patent number: 10803263
    Abstract: A wireless tag reading apparatus includes an input control means, an extraction means, a storage control means, and a determination means. The input control means receives an input of a signal obtained by converting the radio wave received by an antenna that receives a radio wave from a wireless tag. The extraction means extracts the phase of the radio wave received by the antenna from the signal received by the input control means. The storage control means causes the storage medium to store the phase of the radio waves extracted by the extraction means for each reception position at which the antenna received the radio waves. The determination means determines whether the wireless tag that transmitted the radio wave is inside a predetermined region based on the amount of change of phase stored in the storage medium.
