I'm a fellow amateur, but I would say it allows higher bandwidth than X-band. It's a higher frequency range, shorter wavelength. Edit: it might be worse for signal propagation through the atmosphere though... https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Shaping_the_Future/Are_signals_at_W-band_frequencies_good_enough_for_communications https://www.esa.int/Enabling_Support/Space_Engineering_Techn... Probably a bit like 2.4 GHz vs 5GHz WiFi.
