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.

LTE LPWA design and best practices

The LTE LPWA technologies LTE-M and NB-IoT specified in 3GPP Release 13 were designed specifically for the IoT markets and typically coexist in a cellular carrier’s existing operating frequency bands. The lower cost and power as compared to standard LTE has significantly increased the adoption of LTE LPWA to the point that the number of LTE LPWA connections now tops unlicensed LPWA connections. In this section, we will discuss the unique features of LTE LPWA that enable low-cost and low-power IoT devices. As shown in Table 4.3, there is a trade-off primarily in terms of data rates and latency for these features.

Table 4.3 – A comparison of standard LTE with LTE LPWA

Both LTE-M and NB-IoT require a single receive antenna (versus two for standard LTE), low spectrum bandwidth, and low transmit power. Taken together, these reduced requirements lower a device’s cost and complexity. While NB-IoT is exclusively...
