LPWAN: IoT going the extra mile

Let us continue the series of IoT-back-to-basics blog posts. This is part three: (if you missed part 2 you can find it here)

The world of technology is constantly evolving, and with it comes the need for advanced connectivity solutions to support the growing Internet of Things (IoT) ecosystem. As an IoT expert with three decades of experience in connected devices, I have witnessed the evolution of connectivity technologies and their impact on various industries. In this article, we will dive deep into LPWAN (Low Power Wide Area Network), a vital component of IoT connectivity, and explore its features, advantages, and applications.

Most Important Points:

– LPWAN encompasses wireless technologies designed for low-power, wide-area IoT connectivity.
– Choosing between public networks and private build involves evaluating cost, control, and scalability.
– Mobile networks like NB-IoT and LTE-M offer global coverage, simplified installation, and scalability advantages.
– Understanding the unique strengths and limitations of NB-IoT and LTE-M helps select the appropriate technology for specific use cases.
– Alternative LPWAN technologies such as LoRaWAN, Sigfox, Mioty, and 5G NR+ provide additional options for IoT connectivity.

Understanding LPWAN

LPWAN is not a single technology standard but a group of wireless technologies designed to provide long-range, low-power connectivity for IoT devices. It encompasses various protocols and standards; all focused on delivering cost-effective, energy-efficient communication over wide areas. LPWAN technologies are tailored to support low-power IoT devices that require long battery life and can operate over large distances.

Public Networks or Private Build

When considering IoT connectivity options, deciding between utilizing public networks or building a private network infrastructure is essential. Public networks offer connectivity through established technologies, such as 4G/5G or LoRaWAN, operated by different service providers. However, caution is advised with Sigfox due to recent financial concerns. On the other hand, building a private network gives you complete control over the infrastructure, and LoRaWAN is a popular choice for this purpose.

Leveraging Mobile Networks

Mobile networks, particularly NB-IoT and LTE-M, based on 4G and 5G technologies, have emerged as prominent options for large-scale IoT deployments. These technologies utilize existing service provider networks and frequency bands, providing global coverage and seamless integration. Leveraging mobile networks offers advantages such as simplified installation, access to a larger market, international competitiveness, scalability, and reduced device costs.

NB-IoT or LTE-M?

For organizations exploring IoT connectivity through mobile networks, two prominent technologies often come into consideration: NB-IoT (narrowband IoT) and LTE-M. While both are 3GPP-standardized technologies and share the same network infrastructure, they have distinct strengths and limitations, making them suitable for different use cases. Understanding the specific requirements of your IoT project will help determine which technology aligns better with your objectives.

Beyond Mobile Networks: Exploring Alternatives

In addition to mobile networks, several alternative LPWAN technologies have emerged to cater to various IoT use cases. Technologies such as LoRaWAN, Sigfox, Mioty, and 5G NR+ offer alternative options for building Low Power Wide Area Networks. Each of these technologies has unique features, advantages, and considerations, making assessing their compatibility with your specific IoT requirements crucial.

In conclusion, LPWAN technology enables robust and scalable IoT connectivity. Understanding the nuances of LPWAN, including its different technologies and deployment options, empowers IoT experts to make informed decisions and design optimal connectivity solutions for their projects. Whether leveraging mobile networks like NB-IoT and LTE-M or exploring alternative LPWAN technologies, the key is to align the chosen technology with the specific requirements of the IoT application, ensuring seamless and secure connectivity.
