Abstract

A system for transmitting wireless communications within ductwork. The system includes a plurality of transmitter devices for introducing electromagnetic radiation into the ductwork such that the ductwork acts as a waveguide for the electromagnetic radiation, said transmitter devices comprising a transmitter array, wherein the transmitter devices are configured to introduce the electromagnetic radiation using multiple propagation modes. The system also includes a plurality of receiver devices for detecting the electromagnetic radiation within the ductwork, said receiver devices comprising a receiver array.
