Electromagnetic coupler system

[Category : - Telecommunications]
[Viewed 2091 times]

This invention makes it possible to communicate through solid non-metallic walls or ceilings with low microwave power levels. RF beam forming couplers are driven by common LAN (Local Area Network) circuits. For connection to a LAN segment at the other side of a wall or ceiling, transceiver 4 transmits data modulated microwave RF to coupler 6 through a directional step attenuator 10. The reduced signal is received by the coupler system at the other side with a power level low enough to eliminate wireless detection from the outside and enabling the transmission through feet thick concrete walls or ceilings at wide band microwave frequencies with privacy.
