What do you mean 1 data point? It transmits bytes, not data points. I could easily stuff 60 temperature and humidity readings into one hourly 192b packet(ie per-minute weather data). That's 120 data points, not 1. And you could easily double that with simple differential encoding or beyond other compression techniques

Yeah what I meant to underline was that for a critical application you won't be able to react faster than one hour in case the data reports a critical issue. So not suitable for security or any application where you need less than one hour latency. I guess if you need satellite coms maybe the sensor is not in a place you can go in one hour anyway.
