IoT and Edge Computing for Architects - Second Edition

By: Perry Lea

Overview of this book

Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is needed if you want to traverse the spectrum of technologies needed to build a successful IoT system, whether that's a single device or millions of IoT devices. IoT and Edge Computing for Architects, Second Edition encompasses the entire spectrum of IoT solutions, from IoT sensors to the cloud. It examines modern sensor systems, focusing on their power and functionality. It also looks at communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, the book explores IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. It also explains edge computing, routing and gateways, and their role in fog computing, as well as the messaging protocols of MQTT 5.0 and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. The book wraps up the analytics portion with the application of statistical analysis, complex event processing, and deep learning models. The book then concludes by providing a holistic view of IoT security, cryptography, and shell security in addition to software-defined perimeters and blockchains.

LoRa and LoRaWAN

LPWAN also includes technologies that are proprietary and not sponsored by 3GPP. It can be argued that some IEEE 802.11 protocols should also be classified in LPWAN, but the next two sections will highlight LoRa and Sigfox. LoRa is a physical layer for a long-range and low-power IoT protocol while LoRaWAN represents the MAC layer.

These proprietary LPWAN technologies and carriers have the advantage of using the unlicensed spectrum and that, simply, is data plan cost.

LoRa/LoRaWAN can be built, customized, and managed by anyone. There is no carrier or service-level agreement if you choose not to use a carrier. LoRa and LoRaWAN offer a degree of flexibility only seen in CBRS and Multefire. It is important to understand the monetization impact on scaling when building an architecture using any communication.

Typically, technologies like Sigfox and LoRaWAN will be 5x to 10x lower in their data rates compared to traditional 3G or LTE connections...
