Abstract: A ground-based antenna assembly (10) is provided that includes an assembly base (14) defining a substantially horizontal plane (18) and configured for attachment to a residential, commercial or governmental structure. The ground-based antenna (10) also includes a plurality of planar receiving panels (22) having a circular and/or elliptical shape. The plurality of planar receiving panels (22) are radially-spaced about the assembly base (14) and tilted with respect to the substantially horizontal plane (18) for a receiving field-of-view. The ground-based antenna assembly (10) further includes a plurality of planar transmitting panels (26) having a circular and/or elliptical shape. The plurality of planar transmitting panels (26) are radially-spaced about the assembly base (14) and tilted with respect to the substantially horizontal plane (18) for a transmitting field-of-view.

Abstract: Apparatus and a method are described for providing for multiple secure functions in a host or wireless radiotelephone. Access to the functionality of the radiotelephone is provided by means of a smart card or security token features contained therein. The determination of the secure function which is accessed is determined by encrypted credential information carried in the smart card. The smart card may be used for numerous applications, but is particularly useful in conjunction with radiotelephone devices having a plurality of secure communication levels. The radiotelephone device will activate the secure levels based on the security level algorithm carried in the smart card.
