1. A system, comprising:
one or more circuits in a programmable active reflector (AR) device associated with a first radio frequency (RF) device and a second RF device, wherein the one or more circuits are configured to:
receive a request and associated metadata from the second RF device via a receiver antenna array, wherein the request is based on a noise generated by the second RF device;
receive one or more antenna control signals from the first RF device based on the received request and associated metadata;
generate a plurality of controlled RF signal based on the received one or more antenna control signals; and
transmit, via a transmitter antenna array, the generated plurality of controlled RF signals based on the associated metadata to the second RF device within a transmission range of the programmable AR device,
wherein the plurality of controlled RF signals are cancelled at the second RF device based on the associated metadata.
