RF Ground Plane: The module requires an RF ground plane on the rest of the Printed Circuit Board (PCB) area. This
can be located on any layer of the PCB. For best performance, extend the RF ground plane the entire length of the
board. Connect all ground pins and do not notch the ground plane around the module. The bottom of the module is
grounded so be careful of vias or conductive traces located under the modules that are not soldered masked to prevent
shorting. Keep metallic components, connectors, copper traces, internal layers, and ground planes away from the
antenna area in 3D space!
