Patent number: 11683090Abstract: A system uses pulsed lasers to enhance a signal propagation path in a telecommunications network. The system can estimate a signal propagation path, which varies based on a current location of a mobile device relative to a base station. The system can detect a propagation loss due to a condition of a propagation medium including the signal propagation path and determine whether the mobile device is in Line-of-Sight (LOS) of a laser emitter. In response to detection of the propagation loss, the laser emitter can emit a pulsed laser that can enhance signal propagation by mitigating the propagation loss on the signal propagation path. The pulsed laser has a propagation path overlapping the signal propagation path when the mobile device is in LOS of the laser emitter, which is mounted on the base station.Type: GrantFiled: January 18, 2022Date of Patent: June 20, 2023Assignee: T-Mobile USA, Inc.Inventors: George Cummings, Brett Christian, Scott Probasco
