20 Claims

1. A system, comprising:

a first plurality of circuits in a receiver front-end of a reflector device,

wherein the reflector device is in a vicinity of a physical obstructing object at a line-of-sight (LOS) radio path between a first equipment and a second equipment, and

wherein the first plurality of circuits are configured to:

adjust a first amplification gain of each of a plurality of radio frequency (RF) signals received from the first equipment via a first radio path of a non-line-of-sight (NLOS) radio path,

perform a first phase shift on each of the plurality of RF signals with the adjusted first amplification gain to generate a plurality of first phase-shifted RF signals, and

communicate a combination of the plurality of first phase-shifted RF signals to a second plurality of circuits, and

wherein the second plurality of circuits is in a transmitter front-end of the reflector device, the second plurality of circuits are configured to:

perform a second phase shift on each of the plurality of first phase-shifted RF signals to generate a plurality of second phase-shifted RF signals; and

transmit the plurality of RF signals as a directed beam to the second equipment via a second radio path of the NLOS radio path,

wherein the directed beam is transmitted to the second equipment based on the plurality of second phase-shifted RF signals.
