#LoRa technology # IoT applications

In this tutorial, LoRa Technology for IoT applications, we present the main features of LoRa technology and LoRaWAN systems, for the deployment of large-scale IoT applications. Part 2 talk by Ilenia Tinnirello. 

First, we present some basic concepts of LoRa modulation and discuss the implications on coverage and interference-rejection capabilities. We show that collisions between packets modulated with the same Spreading Factor (SF) usually lead to channel captures, while different spreading factors can indeed cause packet loss if the interference power is strong enough.

Second, we discuss some simple models able to quantify the achievable capacity in a typical LoRa cell: we show that high SFs, generally seen as more robust, can be severely affected by inter-SF interference and that different criteria for deciding SF allocations within the cell may lead to significantly different results.

We discuss the capacity improvements that can be achieved by increasing the density of LoRa gateways.

Finally, we present some real-world applications and experimental data from one of the biggest Italian LoRaWAN provider.
