Sunny Coast, I am sure you would have read the 2017 European Neuro Convention Presentation on NTI's announcement on 8 June 2017. Page 9 to 18 explains the alpha, beta, delta and theta brainwaves and the differences experienced between people with ASD condition and "normal". Page 11 shows a graphic presentation of the differences.
I believe the "Normal range" would be best explained in what the company has already presented.
