“…The measurement approach taken is similar to the one described in [4]. As the measurement of Frequency Modulated Continuous Wave (FMCW) signals generated by a RA require very specific and complex measurement equipment, a continuous wave (CW) source feeding the RA antennas was used instead.…”

Civil aviation is considering the use of wireless transmission technology for safety-related on-board machine-tomachine communications. The crucial factor is the availability of a globally harmonized radio frequency band with predictable characteristics in terms of signal propagation and interference induced by other users of that frequency band. Currently the International Telecommunication Union and the International Civil Aviation Organization are establishing the regulatory environment allowing the usage of the band 4. 2-4.4 GHz for socalled Wireless Avionics Intra-Communications. A WirelessAvionics Intra-Communications system essentially provides highly reliable short-range radio links between two or more points on board an aircraft. Since the frequency band 4.2-4.4 GHz is also used for radio altimetry on board civil and state aircraft, it is important to understand the coupling mechanisms between WAIC systems and the Radio Altimeter system onboard the same aircraft as well as onboard different aircraft. For this reason an extensive measurement campaign as described in this paper was carried out. The purpose of this campaign was to assess the degree of coupling between the antennas of both systems for a variety of antenna constellations involving one or two commercial short-haul aircraft of type Airbus A320-200 and A321-200. Keywords-wireless avionics intra-communications (WAIC), coupling measurements, radio altimeter, wireless sensor network.I.

“…The minimum value in the table is 34 dB, providing at least an 8 dB safety margin over the 26 dB IPL Target . Data in the Table 5.6-2 came from [10] but were corrected for a small 2.06 dB calibration error. The error, applies specifically to GS band data only, was discovered and corrected by the original authors after the report publication.…”

“…This includes the allocation of frequencies for wireless sensing on aircraft, along with the determination of RF power levels, and FAA acceptance for aircraft use. There is a concern that wireless devices within the cabin may interfere with aircraft antennas located outside the cabin [37]. Personal electronic devices and cell phones have been tested to determine the effects of wireless devices may have on the aircraft avionics.…”

Abstract-NASA aeronautical programs require integrated vehicle health monitoring (IVHM) to ensure the safety of the crew and the vehicles. Future IVHM sensors need to be small, light weight, inexpensive, and wireless. Surface acoustic wave (SAW) technology meets all of these constraints. In addition it operates in harsh environments and over wide temperature ranges, and it is inherently radiation hardened. This paper presents a survey of research opportunities for universities and industry to develop new sensors that address anticipated IVHM needs for aerospace vehicles. Potential applications of passive wireless SAW sensors from ground testing to high altitude aircraft operations are presented, along with some of the challenges and issues of the technology.
