Abstract

In a first radio frequency (RF) device, circuits determine a non-line-of-sight (NLOS) radio path, and select a first plurality of reflector devices associated with the NLOS radio path from a second plurality of reflector devices. The first plurality of reflector devices, are selected based on a first set of criteria, includes an active reflector device and a passive reflector device, and are controlled to transmit a plurality of RF signals to a second RF device based on a second set of criteria. The second RF device is associated with electronic devices. The first RF signal interferes with a second RF signal of the RF signals. A first type of signal associated with the plurality of RF signals is converted to a second type of signal at the second RF device, and the second type of signal is transmitted by the second RF device to the one or more electronic devices.
