1046  Low-Power Wide-Area Networks (LPWAN)

1046.1 Introduction

Time: ~5 min | Difficulty: Foundational | Unit: P09.C01.INDEX

Low-Power Wide-Area Network (LPWAN) technologies represent a class of wireless communication protocols specifically designed for IoT applications that require long-range connectivity with minimal power consumption. LPWAN fills the gap between short-range technologies (like Wi-Fi and Bluetooth) and traditional cellular networks, enabling battery-powered devices to communicate over distances of several kilometers while lasting years on a single battery.
