<p>A cellular telephone system wherein the handset (20') thereof is connected to the remaining portions (22.92) by an infrared light-link (26). This provides the elimination of the connecting cord with attendant benefits, principally the ability to roam with the handset in the manner of a so-called 'cordless' telephone. Various embodied infrared light-links include a through-the-glass version incorporated with the RF antenna and a bi-directional dash-mounted version (figure 6, figure 7) for automobiles (10) which connects to the handset when inside of the automobile or outside thereof; and also a combined IR interface and dome light unit (54) for disguising and hiding the infrared light-link inside of a vehicle.</p> |
