1067 LPWAN Fundamentals
1067.1 Low-Power Wide-Area Networks (LPWAN)
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.
By the end of this chapter series, you will be able to:
- Understand the defining characteristics of LPWAN technologies
- Identify the key LPWAN protocols: LoRa, Sigfox, and NB-IoT
- Compare LPWAN with other wireless technologies
- Evaluate LPWAN suitability for different IoT applications
- Calculate link budgets and estimate range for LPWAN deployments
- Avoid common pitfalls in LPWAN design and deployment
