NB-IoT is a LTE-based cellular low-power WAN (LPWAN) technology. NB-IoT uses a narrow band of 200 kHz and supports a min. channel bandwidth of 3.75 kHz. Due to these characteristics, NB-IoT is offering unmatched system flexibility and capacity. At the same time, NB-IoT is quite radically focusing on typical IoT use cases with low bandwidth requirements and enables
- network coverage in difficult-to-reach areas,
- low cost battery-powered devices with long zero-touch lifetime and
- applications requiring a high density of IoT devices.
My new book is focusing on NB-IoT device design – from an engineering and a business point of view. Contents has been agreed (by contract) with Springer-Verlag. The book manuscript has been submitted, see below Table of Contents. Work will be published soon – as an eBook (PDF format) as well as a printed version. In the meantime, Springer announced publication date for the printed version: December, 6 2021. The eBook version will be available earlier.
Objective of my book is to assistance to engineers entering the IoT business, provide some inspiration and guidance and help them to take right direction while specifying requirements and ingredients of an IoT project. Various topics are covered: How does NB-IoT work, what are key benefits, which are NB-IoT predestinated use cases and application areas? What are major design ingredients and selection criteria, e.g. for components, suppliers, cloud services. In addition, some important system design and security considerations are explained. Major NB-IoT industry key players are being mentioned, e.g. manufacturers of NB-IoT network modules (modems), network operators and service providers.
A main topic is to explain NB-IoT extraordinary power saving features and how to implement battery-powered IoT devices with ultra-long zero-touch lifetime (i.e. more than 10 years). Two design concepts are covering two typical NB-IoT target applications: one for a monitoring use case providing periodic updates in a “push” operation mode, the other for a security use case providing local data on request only (“pull” operation). In addition, a versatile NB-IoT network evaluation and test tool based on RasPi platform is being introduced.
This book provides a lot of useful information and practical advice for engineering-minded IoT fans.
