Mobile Station Beam Width Control for Wireless Tracking

The patent applies dynamics by making the beam width adjustable rather than fixed. The beam width is dynamically changed based on the distance to the other mobile station: narrower beam width is used when distance is large to maintain signal strength, and wider beam width is used when distance is small to facilitate easier tracking. This dynamic adjustment resolves the contradiction between achieving high-speed communication (requiring narrow beam) and ease of tracking (requiring wide beam).

The patent applies parameter changes by modifying the beam width parameter based on distance conditions. Instead of implementing a complex mechanical or electronic tracking mechanism to maintain alignment, the system changes the beam width parameter adaptively: using wider beams when close to the target makes tracking easier and more reliable, while using narrower beams when far away maintains communication efficiency. This parameter adaptation achieves reliable communication without requiring complex tracking mechanisms.

The system dynamically adjusts beam width based on real-time distance measurements. When the distance to the other mobile station is large, a narrower beam width is used to concentrate signal energy and overcome attenuation. When the distance becomes small, the beam width is widened to reduce tracking accuracy requirements. This dynamic adaptation allows the system to maintain signal strength when needed while reducing tracking precision demands when distance decreases.
