A system and method for processing received transmission signal adapted to be used in high rate communication systems without impairing the received signal energy and without additional expensive components. A route is calculated from a point of origin to an optimal target point from a plurality of spatially separated target points that are allocated to at least one directed segment andor to at least one node. Upon display of a presentation page on the first computer, data representing a given portion of the presentation page is repeatedly broadcast over the communication link. The camera photographs an image of a feature. A width direction is perpendicular to both a flow direction of air in the throttle and the reference vector.
