I love jargon heavy posts. I just dropped an hour learning about o3b, MEO, CPE, low earth orbit, data rates. This kind of googling leads to new hobby pursuits and some times new career thinking.
Now study geostationary c, ku, and ka band transponder capacity, earth stations, vsat modems/dishes/rf chains, to have a better understanding of the current two way satellite status quo.
Ka, as in, radar?
Yes, though two way satellite Ka is generally uses to refer to all of the bands above the "traditional" Ku band FDD frequency channels, but below 31GHz.
Not exactly the same bands as ka radar.
Me too, I've learned so many things by spending a few hours going down the rabbit hole.
