Implementing Cellular IoT Solutions for Digital Transformation

By: Dennis McCain

Overview of this book

Even if you’re an IoT technology manager with a sound understanding of wireless local area network technologies like Wi-Fi and Bluetooth, you may face many unique challenges when implementing a wireless wide area network (WWAN) IoT solution with cellular technologies with respect to choosing the optimal IoT device, cellular connectivity, and architecture. To help you overcome such roadblocks, this digital transformation book guides you in implementing a robust, end-to-end cellular IoT solution using best practices for all aspects of managing the IoT solution. Starting with an introduction to the top IoT markets and solutions in the context of an enterprise’s digital transformation, this book will show you how this leads to cost savings and new business models. You’ll grasp all you need to know about the IoT system components, life cycle, and best practices for implementing an IoT solution. While the book explains all the leading IoT wireless technologies, the focus is on LTE and 5G cellular technologies. With a review of real-world cellular IoT solution case studies and future IoT trends, you'll be ready to work with wireless IoT technologies, devices, and architectures. By the end of this book, you'll be able to identify the best wireless technologies for your IoT use cases and successfully implement cellular IoT solutions addressing key issues in the solution life cycle.

Cellular IoT device architecture

Let us begin our review with an overview of the cellular IoT device architecture shown in Figure 6.1:

Figure 6.1 – Cellular IoT device architecture

Figure 6.1 – Cellular IoT device architecture

At a high level, a cellular IoT device includes a processing unit that runs the device application, an LTE/5G cellular module with the SIM and RF, a power unit for managing the battery and/or energy harvesting (such as solar or thermoelectric), various sensors, and digital/analog inputs and outputs. It could also integrate WLAN radios such as Bluetooth, Wi-Fi, LoRa, and/or LR-WPAN, which we covered in Chapter 3, Introducing IoT Wireless Technologies. Let us examine each of these architecture blocks in more detail.

Processing unit

The processing unit is the brain of the device, which manages all the other peripheral architecture blocks on the device and is where the device firmware application runs, on either a Microcontroller Unit (MCU) or Central Processing Unit...
