Patent ID: 6963305

Claim:
An electromagnetic microwave coupler system for wired, fiber optic and wireless information networks to provide wireless communication through a wall or ceiling of various composition without its alteration, comprising: a transceiver with data controller providing a bridging means for transmission and reception of information modulated microwave signals; microwave coupling device of wavelength-related design for transmission and reception of said microwave signals through said wall or ceiling by using a radio frequency conductive and reflective housing structure with an aperture limited by a Brewster's angle creating a confined electromagnetic radiation field through said wall or ceiling in interaction with an antenna means placed within said structure and located close to said wall or ceiling; wherein, a RF conductive and reflective shielding means is part of said coupling device and is designed such that the said shielding means is surrounding the said aperture to prevent backward radiation of said radiation field while restricting the microwave signal penetration to as small as possible volume; at least one means is provided to secure said microwave coupling device to said wall or ceiling; a microwave signal attenuation means having bi-directional means with low forward signal power losses and high isolation attenuation is provided for control of transmitted said microwave signals to optimize power for a specific said wall or ceiling type and thickness; said antenna means comprises at least one resonator used for both transmission and reception; and, at least one said microwave coupler system each with at least one said coupling device located above the ceiling or behind a wall of a building providing at least one wireless access point for communication through said wall or ceiling to communicate with wireless devices having their own antennas located below or behind said wall or ceiling; and, a second said microwave coupler system is placed at the opposite side of said wall or ceiling for communication with said first microwave coupling device for reception and transmission of said microwave signals through said wall or ceiling.
