Abstract:
This paper presents results of a narrowband measurement campaign conducted in a two different civil aircrafts. Inside a Boeing 737-400 and in an Airbus A340-300 aircraft, the objective being the development of a propagation prediction model which can be used in the deployment of incabin wireless networks. The measurements were conducted at three different frequency bands: 1.8, 2.1 and 2.45 GHz, representative of several wireless services. The path loss factor was found between 2.1 and 2.3 inside Boeing and between 3.3 and 3.6 inside Airbus. The average K-factor in the Airbus aircraft corridors was found between 9.5 and 10.1 dB, for LoS conditions and between 3.7 and 5.0 dB for NLoS cases. In respect the Kfactor inside the Boeing corridor ranges between 12.1 and 12.6 dB. Propagation prediction technique based on Physical Optics was applied to the Boeing 737-400 cabin scenario to obtain comparison of theoretically predicted values and measurements.
