nWP044 - Best practices for cellular IoT development

This document introduces the main aspects and decisions you need to consider before and during your development phase of a low-power cellular Internet of Things (IoT) product.

The sections are structured and ordered chronologically to follow a natural way of designing a cellular IoT device. The first sections cover the initial design decisions you might need to make to get the best possible baseline of your design. This includes overviews about the nRF9160 System in Package (SiP), modem radio, and radio technologies. The importance of network coverage and access is also discussed.

Then, high-level topics such as IP, security, and application protocols are presented. The sections discuss IP protocol choices and recommendations, different security protocols, and available application protocols you can use.

Lastly, the document gives information about certificates, third-party modules from Nordic partners, and support channels.
