    摘要: Radio frequency identification (RFID) tags selected for inventorying using combination of preselect and/or post select criteria. The selection commands can be for selecting according to a tag memory content, by invoking the mask address or by comparing other tag characteristics. Selection criteria can be determined locally at a modem block of a reader or provided to the modem block by higher layers of the reader. Tags meeting the selection criteria are reported to the higher layers for further actions. Some tags may be held while waiting for instructions from the higher layer block(s).

    摘要: Rogue RFID readers are detected by listening to communication between rogue reader and a tag, capturing an identifier associated with the tag from the communication by the reader or by the tag, and checking the captured identifier to determine whether it is a result of a command from another legitimate reader. Audible or visible alerts may be issued, flags may be set, or messages transmitted to an administrator upon determining the operation of the rogue RFID reader. Based on the alert(s) affected tags or the rogue reader may be jammed or an effect of the illegal transmission by the rogue reader may be reversed or tags replaced.

    摘要: RFID tags and chips for RFID tags are capable of being inventoried in one or more early attempts. These tags are capable of then refraining from participating in one or more subsequent inventorying attempts. In some embodiments refraining is performed solely by the tag, while in others it is guided by the RFID reader. In some embodiments, an inventoried indicator in the tag becomes updated upon backscattering. The updated value is used by the tag to recognize a subsequent attempt, and thus refrain from participating in it. This permits the subsequent attempt to be used more intensively for inventorying the more elusive, harder-to-read tags, especially in more demanding scenarios.

    摘要: Systems, software, devices, and methods are described for an RFID reader system to communicate with RFID tags. RF energy encountered in conjunction with using a selected channel is detected. The RF energy can be a signal from another RFID reader. The detected signal is used to adjust a waveform shaping parameter. RF waves can be transmitted from the reader to the RFID tags and RF waves can be backscattered from the RFID tags. At least some of the RF waves transmitted to or backscattered from the RFID tags have a waveform with a shape according to the adjusted waveform shaping parameter.

    摘要: Methods, apparatuses and systems directed to synchronizing upstream and downstream transmissions across routing nodes in a wireless mesh network. The present invention, in one implementation, reduces radio interference between routing nodes in a wireless mesh network. In one implementation, the present invention, also allows for the use of a single radio dedicated to wireless backbone transmissions thereby reducing the cost of routing nodes. In one implementation, at least some of the routing nodes in the wireless mesh network include a second radio and associated wireless communication functionality to provide wireless access to mobile stations.
