Aircraft PLC Channels Characterization: Initial Discussion

This paper presents a characterization of aircraft power line channels limited in the frequency band 1.7-100 MHz. Analyses of frequency response magnitude, additive noise, and channel capacity are described. Two measurement configurations of power lines are considered in order to better understand the aircraft electric power network channel. The harness analyzed belongs to a flight test prototype aircraft Embraer Legacy 450 equipped to perform flight tests. Results show that for a transmission power of -50 dBm/Hz, the upper and lower channel capacities are around 1000 and 900 Mbps, respectively.
