This project is determined practical aircraft hardening techniques for mitigation of airplane system susceptibility to RF energy from Portable Electronic Devices (PEDs) operating from within the fuselage.
The effort included collecting information on PED technologies (e.g. Bluetooth, IEEE 802.11a/b/g, UWB, GSM, CDMA) and counter-measures that have been incorporated or studied either in commercial, military, or non-aviation related programs.
Practical implementation was the main overall focus of the effort. Results of this effort were intended to support regulatory requirements on protecting aircraft from the effects of PED emissions.
Researchers reviewed existing and developing techniques used both within and outside the aviation industry that could be applied or adapted to aircraft.
Researchers examined techniques to reduce coupling path attenuation through door seams, through windows, at antennas (including the processing of intended signal vs. noise), and in airplane equipment enclosures and airplane wiring.
