ARNS-band air to ground radio channel characterization using 902–928 ISM band measurements

This paper presents the results of flight tests conducted in August 2015. During these flight tests, an OFDM-like sequence in the 902-928 MHz ISM band is used to characterize air-to-ground propagation of the 960-1215 MHz ARNS band. The paper gives a brief overview of the measurement setup and procedures, followed by the channel characterization results and an assessment of its applicability to aviation ranging application.
