Abstract

A system, in a radio frequency (RF) transmitter device, dynamically selects one or more reflector devices along a non-line-of-sight (NLOS) radio path based on a defined criteria. Further, the dynamically selected one or more reflector devices are controlled based on one or more conditions. In an RF receiver device, communicates with the dynamically selected one or more reflector devices comprising an active reflector device. The active reflector device comprises at least a first antenna array and a second antenna array. The first antenna array transmits a first set of beams of RF signals to at least the RF transmitter device and the RF receiver device. The second antenna array receives a second set of beams of RF signals from at least the RF transmitter device and the RF receiver device.
