Interest in LEO for IoT grows, new chipset integrates LPWAN with satellites The launch of a system-on-chip (SoC) enabling low power WAN networks to connect IoT devices over low earth orbit (LEO) satellites, by a little-known US start-up, does not by itself signify growth in this field. But combined with other developments involving Tier 1 operators, as well as persistent rumors that Apple will support LEO connectivity in future iPhones, it is clear there is at least a little fire behind the smoke.
