IoT Architecture and Core IoT Modules
The edge computing and IoT ecosphere starts with the simplest of sensors located in the remotest corners of the earth and translates analog physical effects into digital signals (the language of the Internet). Data then takes a complex journey through wired and wireless signals, various protocols, natural interference, and electromagnetic collisions, before arriving in the ether of the Internet. From there, packetized data will traverse various channels arriving at a cloud or large data center. The strength of IoT is not just one signal from one sensor, but the aggregate of hundreds, thousands, potentially millions of sensors, events, and devices.
