ABSTRACT:
A speed measuring system for measuring the speed of a wireless communication terminal communicating with a base station includes an angle measuring unit, a distance measuring unit, a time measuring unit, and a speed calculator. The base station includes a signal tower and an antenna on the signal tower. The signal tower defines a central longitudinal axis perpendicular to the antenna, and the axis intersects the antenna at a point. The angle measuring unit measures an included angle between signal from the wireless communication terminal at any location and the antenna. The distance measuring unit measures a distance between the wireless communication terminal at any location and the point. The time measuring unit measures the time the wireless communication terminal takes from a first location to a second location. The speed calculator calculates the speed of the wireless communication terminal.
