A story of bosses, messengers, and how commands fly through the air
The eIM is the boss: it lives in the cloud, tells devices which profile to use, and manages thousands at once. The IPA is the on-device translator: it receives commands and passes them to the chip. It's a messenger, not a decision-maker.
The translator comes in two versions: IPAd lives in the device's main computer (for smarter devices), while IPAe lives inside the eSIM chip itself: meaning even the tiniest sensor with barely any computer power can still be remotely managed!
Four communication bridges connect everything: ESipa is the main highway for commands and downloads. ES9+' connects to the profile factory. ES11' checks the message board. And ESep is the secret double-signed tunnel for secure commands: it's not a real wire, just a logical path inside the main highway!
Not all devices speak the same language! The system supports HTTPS for smart gateways, CoAPS for tiny battery-saving sensors, MQTT for messaging platforms: and even custom languages. Whatever a device speaks, the system understands!
The IPAe variant lives inside the eSIM chip itself! That means even the tiniest, simplest sensor: one with barely any computer power: can still be remotely managed. The chip does all the thinking.
