LoRaWAN, Sigfox, NB-IoT & LTE-M Compared

The Internet of Things depends on a critical question. How do you connect devices that must operate for years on tiny batteries, often miles from the nearest power outlet? This Elektor Technical Brief provides a practical guide to the technologies that have become the backbone of long-range, low-power IoT connectivity. Compiled by the Elektor Content Team, this concise technical brief examines the real engineering tradeoffs behind today’s leading Low-Power Wide-Area Network (LPWAN) technologies: LoRaWAN, Sigfox, NB-IoT, and LTE-M.

By referencing a wide range of Elektor articles and other online content, this document explains why link budget, noise, bandwidth, and power consumption ultimately determine system performance. From there, it explores the architectures, strengths, limitations, and deployment realities of each major LPWAN technology, helping you understand not just how they work, but when and why to use them.

Whether you’re designing smart meters, industrial sensors, agricultural monitoring systems, asset trackers, or connected infrastructure, this guide provides the insights needed to make informed connectivity decisions. Along the way, you’ll discover:

Why LPWAN technologies emerged and where they fit in the IoT landscape
The RF fundamentals that drive range, reliability, and battery life
Details about LoRaWAN, Sigfox, NB-IoT, and LTE-M
Practical comparisons of power, coverage, latency, cost, and deployment models
Guidance for selecting the right LPWAN technology for your application
Emerging trends shaping the future of long-range IoT connectivity

Clear, accessible, and grounded in real engineering practice, this Technical Brief helps you move beyond specifications and marketing claims to understand what matters most. If you’re building connected products that need to survive in the field — not just in the lab — this is the LPWAN guide you’ll want at your side.
