Welcome back to evan.nerding! Having mastered the wireless foundation in Chapter 1, we are now ready to tackle the full system in Chapter 2: The Internet of Things (IoT).
This episode moves past the buzzwords and provides a detailed, complete technical breakdown of the IoT Ecosystem. We define exactly what an IoT system is from the perspective of an administrator and engineer.
We deep-dive into the four critical architectural layers of a wireless IoT solution:
Sensing Layer (The Edge)
Network Layer (The Transport)
Middleware/Platform Layer
Application Layer
Understanding these layers is essential for any OT professional because it dictates where security controls must be placed and how troubleshooting should be segmented.
We also explore the key components of an IoT solution—from the edge sensors and actuators to gateways and the cloud platform—and examine the use cases for IIoT (Industrial IoT) and enterprise systems covered by the CWISA.
Mastering the architecture is the key to successfully planning and deploying reliable wireless solutions.
Tune in next time as we dive into the specific Wireless Technologies (BLE, Zigbee, LoRa) that make the IoT possible!
