152  Architectural Enablers

152.1 Overview

The Internet of Things became viable when four technologies converged: cheap computing, miniaturization, long-lasting batteries, and diverse wireless protocols. This series explores these foundational enablers that make billion-device IoT networks economically possible.

NoteKey Takeaway

In one sentence: IoT became viable when four technologies converged - cheap computing, miniaturization, long-lasting batteries, and diverse wireless protocols - enabling billion-device networks at costs impossible a decade ago.

Remember this: If your sensor costs $20, your annual battery and connectivity costs should be under $2 - otherwise you have chosen the wrong technology stack.
