Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 Detecting a cellular device location in a given room by its signal, using a phased-array antenna. Our individual goal in this project was to check whether the system's behavior is close enough to theory - if not, then to do an adjustments and to solve other problems in the system, like reflections.

Specification המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 4 2 Multi-beam antenna at each side of the room for full coverage. The antennas and the cell-phone are placed 1.14m high from the floor in the room. The cell-phone is on a shelf, with 1m length. The distance between the antennas and cell-phone is 2m. We need to detect whether the cell-phone is on the right side of the shelf, or on the left side. In other word – our detection resolution is 0.5m.
