Department of Telecommunications and Media Informatics

We live in the world of wireless connectivity and IoT every day. A whole set of

engineers are researching future communication solutions. In my dissertation, I am

dealing with a recent LoRaWAN radio frequency network. LoRaWAN networks have

been specifically developed for IoT devices, with long range capability and low power


At the beginning of my dissertation, I briefly review some basic required

knowledge for radio communication. Through an example I present transmission

blocking factors and signal losses during the communication. In most of the research

section I present the network architecture of LoRaWAN.

The design and implementation section details the construction of an energy efficient

measuring device, that uses the LoRaWAN network to send the information to

an Internet service. At the end of the dissertation, I make some measurement and

calculation to the efficiency of the finished device. I analyze the achieved results and give

an outlook for future development opportunities.
