Methods and devices for performing dynamic compensation of a phased array RFID reader are disclosed herein. An example method includes configuring an RFID reader having an antenna array to compensate for determined antenna element phase-shift errors. The method includes exciting a reference antenna element of the antenna array, emitting an emitted signal, receiving the emitted signal via a receiver antenna element of the antenna array, and generating a received signal. The method further includes determining, by a processor, a phase shift of the received signal relative to the emitted signal, and determining a phase-shift error. The method then includes configuring the RFID reader to compensate for the determined phase-shift error associated with the receiver antenna element in response to receiving an RFID tag signal.

A bioptic barcode reader configured to be supported by a workstation and having a lower housing comprising a platter having a generally horizontal window and a tower portion extending generally perpendicular to the lower housing and having a generally vertical window. A multi-axis radio-frequency identification antenna assembly is positioned within the tower portion of the bioptic barcode reader and includes first, second, and third antennas. The first antenna is configured to emit a radiation pattern oriented in a first direction, the second antenna is configured to emit a radiation pattern oriented in a second direction, substantially orthogonal to the first direction, and the third antenna is configured to emit a radiation pattern oriented in a third direction, substantially orthogonal to the first direction and the second direction.

Various apparatuses for use in a wireless network are disclosed. A first apparatus comprises two antennae oriented orthogonally, a biosensor capable of reading a user's fingerprint, and a housing comprising a groove for guiding a user's finger, the groove physically separating the antennae, effectively creating a radome for each antenna. A second apparatus comprises a printed circuit board (PCB) a port, a shell enclosing the PCB, and at least one horseshoe gasket, the shell and gasket creating a waterproof seal isolating the port and the external environment from the rest of the PCB. A third apparatus comprising a bracket for attaching a housing to a building material, an aiming annulus for aiming the housing and the housing. Wherein two or more of the bracket, aiming annulus and housing may be joined in order to mount and aim the housing using one or more structures on the components.

A reading device includes an antenna, a data storage unit, and a controller. The antenna is configured to receive tag information from RFID tags attached to objects in a receiving range. The data storage unit stores an object ID in association with a predetermined total number of RFID tags on an object corresponding to the object ID. The controller is configured to start a reading operation in which the antenna emits radio waves and receives tag information from the RFID tags. The controller counts the number of RFID tags associated with the object ID according to the tag information received during the reading operation. The counted number is compared to the predetermined total number associated with the object ID, and the controller controls a timing for terminating the reading operation based on the comparison.

A method for streaming sensor data from a set of radio-frequency identification (RFID) tags includes determining an initial communication approach to be performed with respect to each RFID tag. The method also includes managing access to the RFID tag by refining the initial communication approach based on records of successes and failures of the initial communication approach. A radio-frequency identification (RFID) system is also disclosed, the system comprising one or more processors and a memory system comprising one or more non-transitory computer-readable media storing instructions that, when executed by at least one of the one or more processors, causes the system to perform operations for streaming sensor data from one or more RFID tags to one or more RFID readers.
