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.

Network topologies

As shown in Figure 3.1, there are 3 primary network topologies used in wireless networks, with the mesh and star topologies being the most common:

Each IoT WLAN and WWAN technology uses specific network topologies, and there are advantages and disadvantages to each topology. For example, mesh topologies used with many Wireless Personal Area Networks (WPANs) and recent WLAN technology releases have the main advantage of network resiliency where the failure of one device does not disrupt connectivity due to redundant connections. The disadvantages of a mesh topology are the complexity of the network and device setup, as well as latency issues in traversing the network. In the case of star topologies used in cellular and WLAN technologies, the main advantages are reliability, efficiency, and centralized network management. The primary disadvantages of star topologies are the cost...
