Abstract: Disclosed herein are systems and method for using a cellular communication chain integrated with RFID wireless communication to communicate with an external RFID tag and a cellular wireless base station. A front end circuit can receive a first RF signal as input and can provide, as output, a processed first RF signal for wireless communication via a cellular network and be a low-band signal. An RFID circuit can generate a second RF signal for wireless communication with an RF identifier tag. A switch circuit or one or more toggle switches can be configured to route the processed first RF signal for transmission via an antenna for the wireless communication via the cellular network and route the second RF signal for transmission via the antenna for the wireless communication with the RF identifier tag.

Abstract: The disclosed hybrid shielding structure may include a printed circuit board (PCB) that is to be overmolded with at least a portion of molding compound. The PCB may include various electronic components disposed thereon. The hybrid shielding structure may also include conductive trenches and conductive fences that are disposed on the PCB. The conductive trenches and the conductive fences may provide an electromagnetic shield for at least a portion of the electronic components of the PCB. The hybrid shielding structure may further include a conformal shielding and a PCB ground flood and ground layers. Various other systems, electronic devices, apparatuses, and methods of manufacturing are also disclosed.
