Abstract

A virtual wireless local area network system and method utilizing impulse radio wherein transmission rates (bit rates) can vary according to the impulse radio transmission quality (signal to noise ratio) and wherein the position of the user can be determined and said user can be directed to an area of greater transmission rates and wherein a plurality of impulse radio portals can be utilized and switched between to maintain high levels of transmission rates while a user is moving within a predetermined area.
