How do you connect an IoT device that needs to operate for years on a small battery, potentially miles from the nearest power source? Choosing the right wireless technology is one of the most important engineering decisions in any long-range IoT design.
 

Elektor has released a new Technical Brief, LPWAN Decoded: LoRaWAN, Sigfox, NB-IoT & LTE-M Compared, providing a practical engineering guide to the technologies behind today’s low-power, wide-area IoT applications.

Rather than simply comparing specifications, the brief examines the fundamental engineering considerations that determine real-world performance, including link budget, noise, bandwidth, range, reliability, and power consumption. It then looks at the architectures, advantages, limitations, and deployment models of four major LPWAN technologies: LoRaWAN, Sigfox, NB-IoT, and LTE-M.

The guide is designed to help engineers understand not only how these technologies work, but also when and why one may be a better choice than another.

Topics covered include:
 

  • Why LPWAN technologies emerged and where they fit into the IoT landscape
  • RF fundamentals affecting range, reliability, and battery life
  • The key characteristics of LoRaWAN, Sigfox, NB-IoT, and LTE-M
  • Practical comparisons of power consumption, coverage, latency, cost, and deployment
  • Factors to consider when selecting an LPWAN technology
  • Emerging trends in long-range, low-power IoT connectivity


The Technical Brief is particularly relevant to engineers developing smart meters, industrial sensors, agricultural monitoring systems, asset trackers, and connected infrastructure.

Compiled by the Elektor Content Team and drawing on a range of Elektor technical articles and other online resources, LPWAN Decoded is intended as a concise, practical reference for engineers who need to make informed connectivity decisions.

LPWAN Decoded: LoRaWAN, Sigfox, NB-IoT & LTE-M Compared is available now as a PDF Technical Brief. Member price: €13.46; non-member price: €14.95
