This paper presents an exhaustive comparison of channel measurements and appropriate channel statistics at 28 GHz, 38 GHz, and 130 GHz in the light of massive measurements conducted in an aircraft cabin environment. A total of 84 transmitter-receiver (Tx-Rx) positions are measured, covering both line-of-sight (LoS) and non-line-of-sight (NLoS) cases, with Tx-Rx distances ranging from 1 m to 10 m. The close-in and floating-intercept path loss models are presented for the cabin environment, and root-mean-square (RMS) delay spread (DS) and angular spread (AS) are compared and analyzed. The results indicate that the path loss exponent (PLE) is smaller than the free space PLE in the LoS aisle case over all measured frequencies. Moreover, the RMS DS and AS decrease as frequency increases in LoS and NLoS cases. This work can be applied to the design and optimization of the wireless communication system within the aircraft cabin.
