A mobile communication system includes at least three transmission antennas of first to third transmission antennas, and uses an overlapped antenna scheme for grouping the first and second transmission antennas into a first transmission antenna group and grouping the second and third transmission antennas into a second transmission antenna group. A pair of outer manifold elements sandwich an intermediate manifold element. A biometric identifier is automatically captured for validating the identifiable attributes by confirming that the asserted identity matches identifiable attributes.
