Fractional Bands uses a modelisation of price variation by a Fractional Brownian Motion, that incorporates the consideration of the Fractal dimension, contrary to the Bollinger Bands, which are based on a Wiener Brownian Motion (a particular case of the Fractional Brownian Motion). They also use a different equation from the Fractal Bands (https://www.mql5.com/en/code/8895). This difference, while being more consistent with the model on a mathematical point of view, does not seem to provide an indicator as interesting at a trading point of view. Nonetheless, it might still be of some use in combination with other indicators.

Here is the Fractional Bands (in limegreen) with the Fractal Bands (in red), both share the same MA, which is the FRASMA (https://www.mql5.com/en/code/8866):
