But what does this mean for the FTA (Free To Air) Satellite systems? Will we also need to upgrade our receivers as well? Haven't found an answer so far... but for OTA (Over The Air)...

"Will I need a new TV or tuner?
Well...yes. Sort of. There is no intention in making ATSC 3.0 backward compatible. This is a huge leap forward, and that's only possible if the standards developed in the early '90s (which in turn were hamstrung by tech from the '50s) are left behind.
However, it's going to be a long time before this will be an issue. Initially there's going to be bandwidth sharing, so current ATSC 1.0 tuners will still work well into the 3.0 transition. There will also be multiple options to get the new signal to older TVs. Think HDMI dongles, standalone tuners, perhaps even whole-home tuners that receive the signal and then send that over your home Wi-Fi.
Since an ATSC 1.0 tuner box can be had right now for $40, it's likely this aspect will be worked out inexpensively for the "legacy" TVs still in use, just like how HD is available now on all the old SD TVs still in use.
Once the standards are finalized, you'll start seeing ATSC 3.0 tuners in TVs, hopefully with a more marketing-friendly name like "4K Broadcast Ready" or something. But we're a few years away from that."
