His innovative approach has led to the development of a unique device that enhances the measurement and analysis of cellular signal strengths.
Latest Patents
Joseph A Schifferdecker holds a patent for a Cellular-system signal-strength analyzer. This device is a manually-movable, portable analyzer designed for measuring, recording, and displaying geographically-located downlink cellular-communication-channel signal strengths. It is particularly useful in non-vehicular pedestrian areas and inside buildings. The analyzer features a cellular-telephone scanning receiver housed within a backpack worn by the operator. This design allows for mobility while traversing the areas to be analyzed. The device includes a height-adjustable antenna mast made from telescoping tubes, which supports a self-resonant antenna. This antenna's elevation can be varied to determine signal strengths at different pedestrian heights. Additionally, the backpack houses a controller and a laser rangefinder with a built-in compass, which inputs geographic location data to the controller. An arm-held computer connected to the controller records and displays the signal strengths of selected cellular-communication channels for various locations throughout the analyzed areas.
