1.1 Introduction
This chapter introduces the context and motivation for studying LoRa, outlines the objectives
and scope of this project, and sets the stage for further exploration of its potential.
1.1 Background
LoRa was initially developed by Cycleo, a French company, and later acquired by Semtech.
It operates as a physical layer modulation using Chirp Spread Spectrum (CSS), offering
resilience to interference and enabling long-range communication. LoRaWAN, the
corresponding MAC layer protocol, extends these benefits with a scalable star-of-stars
network topology that supports large-scale IoT deployments. [1]
The flexibility of LoRa enables its deployment in unlicensed spectrum bands, reducing
regulatory constraints and deployment costs. Its ability to provide reliable communication
over distances up to 20 km in rural settings and several kilometers in urban areas has made it
a leading choice for IoT connectivity

1.2 Problem Nature
Modern IoT systems encounter several challenges:
1. Coverage Limitations: Urban environments with dense obstructions and rural areas with
sparse infrastructure pose significant barriers to conventional communication
technologies.
2. Energy Efficiency: IoT devices rely on limited power sources, often requiring months or
years of battery life to avoid frequent maintenance.
3. Cost of Deployment: Scaling IoT networks with traditional communication solutions
often leads to high capital and operational expenditures.
LoRa mitigates these issues by providing a reliable and efficient communication system that
ensures long-range connectivity and extended battery life. However, optimizing its deployment
and understanding its full potential remains an active area of research.
