Hello again
I do not work for Orange. This is a truly independent view.
According to their coverage map, Orange 4G covers the whole of Tortosa and surrounding area. So why bother using an obsolete system like Wimax ? The future is LTE (or 4G). Most users should be able to get a good signal and hence decent upload and download speeds using the provided modem and the attached antenna. If the signal is borderline you can put up an external antenna (as I have). Changing Wimax suppliers is like changing one donkey for another. Not much use for daily travel to Barcelona
