Problems solved by technology

[0003] The second problem is that the ability of the mobile phone to connect to a large number of base stations at the same time also degrades the transmission and switching infrastructure of the terrestrial carrier
A major technical problem is that passengers using mobile phones on board are not guaranteed to be connected to picocells inside the aircraft
thus difficult to allow only wireless services supported by onboard picocells while excluding all others

Embodiment Construction

[0019] The following description of preferred embodiments is exemplary only and is by no means intended to limit the invention, its application or uses.

[0020] see figure 1 , which shows a wireless communication system 10 according to a preferred embodiment of the present invention. An exemplary aircraft 12 includes a fuselage 14 and a plurality of windows 16 disposed in the fuselage 14 . Each window 16 includes a conductive film 18 disposed on at least one surface thereof. An unshielded window 20 lacking conductive film 18 is shown for further detailed discussion below.

[0021] One or more wireless cellular devices 22 are wirelessly linked to one or more picocell antennas 24 via a radio frequency (RF) signal path 26 . In the preferred embodiment, picocell antennas 24 are each connected to one of a plurality of picocell / gateway transceivers 70 via wireless data lines 36 . Similarly, one or more passenger wireless network devices 32 are connected to one or more wireless ...

Abstract

A system and method limit transmission of wireless electromagnetic device radiation through the windows of a mobile platform 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.

Description

technical field [0001] In general, the present invention relates to wireless communication devices, and in particular to devices and methods for restricting transmission and reception of wireless communication devices. Background technique [0002] The use of personal wireless devices such as cellular telephones, notebook computers, and personal digital assistants for operation on mobile platforms, generally referred to herein as aircraft, creates several problems. One problem is that a cellular telephone handset on an aircraft at flight altitude (eg, about 10,668 meters (35,000 feet)) has a line-of-sight visibility of about 426 kilometers (265 miles) in all directions. This area can contain tens, hundreds, or even thousands of cellular telephone base stations, causing interference and reducing system capacity over a wide area. A single cell phone call at 10,668 meters can use spectral resources equivalent to tens, hundreds or thousands of terrestrial cell phone calls. [...
