Microwave is a ridiculously broad term. By some definitions it is any signal from about 300MHz to 300GHz, but in the industry we don't really consider it microwave until you get to L-band (1-2GHz), and even then, compared to a lot of stuff we do that's extremely low frequency (I've worked mostly in X, Ka and E-bands - ~7-9, 18-19, 28-31 GHz up to 80-90GHz). But WiFi and cellular are definitely microwave, as are the big point-to-point links you're talking about. Not that I'm agreeing with the parent comment - having worked in the microwave comms industry (and a little bit of radar) for about 10 years, the best explanation I've heard for 'Havana Syndrome' is closer to food poisioning than anything to do with RF. I think the US Government has basically walked back any claims that they were actual attacks recently too. |
