Portable Wireless Adapter for Avionics Location-Based Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems in aircraft lack secure and efficient methods to limit wireless data transmission to within the aircraft, potentially exposing sensitive information and bandwidth to unauthorized devices and frequencies.
Innovation Solution
A portable wireless communications adapter that uses a Wireless Avionics Intra-Communication (WAIC) frequency range between 4.2 GHz and 4.4 GHz, equipped with a location sensing module to determine its position within the aircraft and selectively enable or disable transmission, ensuring compliance with WAIC standards and enhancing security by only allowing communication between authorized devices and aircraft systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is enabled in standard frequency bands (900 MHz, 2.4 GHz, 3.6 GHz, 5 GHz, 60 GHz) for portable electronic devices, then ease of operation and compatibility are improved, but security and bandwidth control deteriorate due to accessibility to unauthorized devices
Solution Approach 1:
The patent changes the frequency parameter from standard consumer bands to the specialized WAIC band (4.2-4.4 GHz), creating a dedicated wireless spectrum for avionics communications that is separated from commercial devices while maintaining wireless communication capabilities
Solution Approach 2:
The patent introduces a wireless transceiver as an intermediary device that enables portable electronic devices to communicate with aircraft systems over the WAIC band, acting as a bridge between standard consumer devices and avionics systems while enforcing security protocols
2Adaptability or versatility
If wireless communication is allowed outside the aircraft, then adaptability and versatility are improved, but security and bandwidth control worsen due to exposure to unauthorized devices and frequencies
Solution Approach 1:
The patent implements dynamic control of the wireless transceiver based on geographic location, automatically enabling or disabling transmission capabilities based on whether the aircraft is within authorized geographic boundaries, thus adapting security measures to operational context
Solution Approach 2:
The patent uses geographic location data as feedback to control transceiver operation, creating a closed-loop system where location information continuously informs transmission decisions to maintain security while enabling legitimate communications

AI summary
A portable wireless communications adapter includes a wireless receiver, a wireless transmitter, an electronic interface connector, and a location sensing module. The wireless receiver is configured to receive wireless data over a Wireless Avionics Intra-Communication (WAIC) frequency range between 4.2 gigahertz (GHz) and 4.4 GHz. The wireless transmitter is configured to send wireless data over the WAIC frequency range between 4.2 GHz and 4.4 GHz. The electronic interface connector is configured to mate with a portable electronic device for communication of the wireless data with the portable electronic device. The location sensing module is configured to determine a location of the portable wireless communications adapter relative to an interior of an aircraft based on WAIC communications received at the wireless receiver and selectively enable and disable the wireless transmitter based on the determined location.
