    Abstract: A barcode reader configured to be supported by a workstation and having a housing with a window. A multi-axis radio-frequency identification antenna assembly is positioned within the housing of the 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.

    Abstract: A bioptic barcode reader configured to be supported by a workstation and having a lower housing with a platter having a generally horizontal window and a tower extending generally perpendicular to the lower housing and having a generally vertical window. A radio-frequency identification radio is positioned within the lower housing and is communicatively coupled to a feed patch positioned within the lower housing and proximate, but spaced apart from, the platter such that the feed patch is capacitively coupled to the platter and configured to energize the platter such that the platter is operative as a radio-frequency identification reader antenna.

    Abstract: An RFID echo cancellation assembly includes: a circulator defining a transmission path from a transmit module to an antenna module, and a reception path from the antenna module to a receive module; a combiner on the reception path between the circulator and the receive module; a variable reflector for applying a cancellation signal to the combiner; a controller for setting an operational parameter at the variable reflector according to an attribute of a transmitted signal from the transmit module; and a coupler defining a segment of the transmission path between the transmit module and the circulator, and a cancellation path between the variable reflector and the combiner. The coupler couples a portion of the transmitted signal to the variable reflector, whereupon the variable reflector generates the cancellation signal based on the operational parameter, for transmission to the combiner via the cancellation signal path.

    Abstract: Systems and methods to co-locate RFID readers with in-band sensor networks, such as LoRa sensor networks, are disclosed herein. An example arrangement is a co-located device that includes a dual-mode transceiver configured to communicate with targets operating in a first protocol (e.g., RFID) and other targets operating in a second protocol (e.g., LoRa). The example arrangement includes a dual-mode controller that operates the dual-mode transceiver to communicate via the first protocol during a first time period while disabling communication via the second protocol and to communicate via the second protocol in a second time period while disabling communication via the first protocol.
