Wireless signal distribution in a building HVAC system |
摘要 |
The present invention is directed to a system for using the ductwork of a building for transmitting electromagnetic radiation. The system includes a device for introducing electromagnetic radiation into the ductwork such that the ductwork acts as a waveguide for the electromagnetic radiation. The system also includes a bi-directional coupler positioned to re-radiate the electromagnetic radiation around an obstacle. The system further includes a device for enabling the electromagnetic radiation to propagate beyond the ductwork. The present invention is also directed to a method for transmitting electromagnetic radiation using the ductwork of a building and a method for designing a system for transmitting electromagnetic radiation in the ductwork of a building.
