In the future of telecommunications, every object will be connected to the Internet.
These objects will be forming a network that senses and collects data from their
environment. The name of this network is Internet of Things (IoT). It opens many new
possibilities for applications, such as automating certain, previously manual, activities.
Considering the impact that the classical Internet had on our lives, one can imagine the
magnitude of the change that the IoT will bring.
In order to succeed, it needs the development of new communication protocols, that
suits its requirements. It does not necessarily need high speeds, as the sheer number of
devices connected to it, will provide huge amounts of data. Low Power-Wide Area
Networks (LP-WAN) is a novel communication paradigm, that addresses the
requirements of IoT for long range communications and low energy consumption by
sacrificing the high data rates.
The purpose of this thesis is to study and implement LoRa, a LP-WAN communications
technology, proposed by Semtech. It is low power, bandwidth scalable, resistant to
interference, fading and the Doppler effect. Furthermore, it can be used for long range
transmissions. These properties make LoRa ideal for the IoT.
