Wireless communication inside shielded envelope
First Claim
1. A mobile platform window system able to attenuate electromagnetic radiation between interior and exterior areas of said mobile platform, wherein an envelope of said mobile platform defines a boundary between said interior and exterior areas, said window system comprising:
- at least one window disposed on said mobile platform;
an electromagnetic radiation shielding layer applied to said window; and
at least one electrically conductive member electrically joining said shielding layer to said envelope of said mobile platform.

Abstract
A system and method limit transmission of wireless electromagnetic device radiation through the windows of a mobile platform outer envelope. The mobile platform includes at least one window on an outer envelope. A shielding layer is applied to the window and electrically grounded to the outer envelope. At least one transceiver hub is located within the mobile platform receiving and/or transmitting the electromagnetic device radiation. An off-board communication device wirelessly communicates with the transceiver hub. The shielding layer attenuates a portion of the radiation contacting the window. Only a communication path between the transceiver hub and the off-board communication device is therefore operable. Wireless device transmission and/or reception via a window path is effectively blocked by the shielding layer, decreasing the potential for disruption to mobile platform electrical systems and interfering with ground-based communication systems.

12. A system to limit the transmission of electromagnetic radiation through one or more windows penetrating an outer envelope of a mobile platform, the electromagnetic radiation being generated by wireless devices located within the outer envelope, said system comprising:
-
an electromagnetic radiation shielding layer applied to said window and electrically grounded to said outer envelope;
at least one wireless transceiver hub located within the outer envelope in wireless communication with the wireless devices; and
an off-board communication device located remote from the outer envelope in wireless communication with said transceiver;
wherein said shielding layer operably attenuates the electromagnetic radiation such that a communication path between the mobile platform and said off-board communication device is operable only between said transceiver and said off-board communication device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
