Systems and methods are disclosed for a first WiFi Direct device to receive a machine-readable label from a second WiFi Direct device to provide information on the P2P WiFi capability of the second WiFi Direct device to aid the two devices in establishing a WiFi Direct connection. The methods involve the use of single andor multiple sensor group systems to provide qualitative andor quantitative estimates of uptake andor penetration. The package includes a base made from a dielectric material which includes vias which contain a conductive material and are electrically coupled to the ground potential of the printed circuit board. Interaction with the GUI widgets also facilitates the preview of the selections that are not in the current view, thus making it easier to determine what has been selected without having to navigate to the view that contains those selections. The DC subband is then entropy encoded into the bitstream.
