Abstract: Methods and systems for providing an asset communication system are described. One asset communication system includes an active communication subsystem including a first radio transceiver, a passive communication subsystem including a second radio transceiver configured to transmit and receive data using radio waves for communication and power, and a sensory subsystem. The sensory subsystem can include one or more sensors, for example, an ambient environment sensor. The asset communication system further includes a synchronous trigger controller for activating the active communication subsystem according to a schedule, and an asynchronous trigger controller for activating the active communication subsystem based on a signal received from a sensor or the second radio transceiver.

The sensory subsystem can include one or more sensors, for example, an ambient environment sensor. The asset communication system further includes a synchronous trigger controller for activing the active communication subsystem according to a schedule, and an asynchronous trigger controller for activating the active communication subsystem based on a signal received from a sensor or the second radio transceiver.

Abstract: A method is provided for a remotely-deployed field device to automatically select one of different mobile network modes to communicate with a server computing device. The field device is configured to maintain consistent and reliable connection with the server computing device by automatically switching between different mobile network modes that are selectively open and active based on various criteria, such as technical and/or business considerations. The automatic selection of mobile network modes is achieved in a submissive mobile network connection regime in which the remotely deployed field device autonomously operates to submit to whichever mobile network mode is open and active under preset criteria.

Abstract: A collapsible storage rack includes an integral RFID tag scanner configured to read RFID tags of products stored thereon. The storage rack is adjustable between an expanded configuration and a collapsed configuration.

Abstract: A modular RFID tag scanner includes a control unit and multiple signal distribution units. The signal distribution units include multiple antennas within a single housing. The signal distribution units are each connected to the control unit by an RF transmission line. The configuration of the modular RFID tag scanner permits easy construction or retrofitting of a product storage structure to scan RFID tags on products, such as to monitor product inventory on the product storage structure. Methods of installing and using an RFID tag scanner are also disclosed.

Abstract: An antenna subsystem includes an antenna and a radio frequency (RF) feed structure. The antenna subsystem includes a signal layer, a ground plane layer, and a middle layer arranged therebetween. The RF feed includes a substrate, a port, and a conductive layer. The port is arranged and configured for selective coupling with a transmission line. A conductive layer includes a first portion electrically connected to the port, which transfers an RF signal between the transmission line and a signal layer. The conductive layer also includes a second portion electrically connected to the port, which electrically couples a ground conductor of the transmission line to the ground plane.

Abstract: An inventory monitoring system including a data collection and transmission module and a data evaluation module. The data collection and transmission module receives data from an RFID tag and transmits the data to the data evaluation module to thereby enable the presence of a product to which the RFID tag is attached.
