Introduction

This article is designed to help those embarking on a new business venture or concept using LoRaWAN technology to understand the options and impact of the choice of LoRaWAN network server type. This article assumes a basic level of knowledge of LoRa and LPWANs and offers the reader clarity on the possible architectures available by virtue of different LoRaWAN Network Server implementations.

LoRaWAN Architecture

LoRaWAN itself defines and end to end data delivery solutions as illustrated in Figure below . End devices are predominately various types of sensor that communicate with LoRaWAN gateways using the LoRa physical layer protocol predominately on sub-GHz license-exempt bands such as 868MHz in EU, 915 MHz in USA & 470MHz in China.
