1. A computer-readable storage medium, excluding transitory signals and carrying instructions, which, when executed by at least one data processor of a system, cause the system to:
establish a millimeter wave (mmW) communication channel on a 5G telecommunications network between a base station and a mobile device,
wherein the mmW communication channel includes a signal propagation path from the base station to the mobile device;
estimate the signal propagation path in accordance with an antenna beam generated based on a beamforming operation to communicate uplink/downlink signals between the base station and the mobile device,
wherein the signal propagation path varies based on a current location of the mobile device relative to the base station and in accordance with the antenna beam;
detect a signal propagation loss to the mmW communication channel due to a condition of a propagation medium including the signal propagation path;
determine whether the mobile device is in Line-of-Sight (LOS) of a laser emitter,
wherein the laser emitter is configured to emit a laser in a coverage area of the 5G telecommunications network; and
in response to detection of the signal propagation loss, cause the laser emitter to emit a pulsed laser configured to enhance signal propagation for the mmW communication channel by mitigating the signal propagation loss relative to the signal propagation path,
wherein the pulsed laser has a propagation path overlapping the signal propagation path when the mobile device is in LOS of the laser emitter.
