Yes, very heavy rainstorms do degrade the WiMax signal considerably. However the precipitation is always (a) confined to a narrow area right "on the beam" and (b) fast moving, so the problem usually lasts for not more than ten minutes and we are talking about two or three times a year. We do not lose any WiMax signal on a normal rainy day.
Compared to satellite transmissions on which I also have a signal meter, it's more reliable. The satellite not only loses the signal during heavy LOCAL rainstorms but goes down with medium to high altitude wind (which is a frequent ocurance where I live) and also twice a year as the sun passes "behind" the satellite as seen from my location.
I spent today running a cable and installing a phone socket where the Prime User of the telephone sits in the evening, quite took me back to my GPO Tech 2A days......when I also worked on setting up the UK's microwave telecomms network, which also suffered attenuation in heavy rain. Presumably still does ?
