Thuraya, Inmarsat and Iridium are all narrowband low data rate solutions. It's unusual to see DVB-S2(x) used at symbol rates below 1 msps. Above 1 msps the DVB-S2(x) standard has become commonplace, mostly on the forward link of TDMA systems but also SCPC high
rate modems. The big move now is to unify commercial satellite air interface with 5G. There is a 3GPP working group working on the standards. The idea is to make satellite a seamless part of the 5G network.</div>

<div dir="auto">Thuraya, Inmarsat, and Iridium all use different signaling approaches, but they all appear to be very different from DVB-S2x which, I think, came out of the VSAT world. <br>
I’m not saying that they couldn’t use it. Do they plan to? If so, for what reason?
