Although the concept of IoT (Internet of Things) became mainstream a few years ago, its true potential has yet to be realized.
The fact that companies with great market influence participate in its standardization and research significantly contributes to its growth.
And we need standards and technologies, because without them the promises of IoT can not become a reality.
Gathering of measured values from several environmental sensors is not a trivial process.
The currently available wireless solutions were designed for various purposes.
Looking at their capabilities the most obvious trade-off is between transmission range and data rate.
In my thesis I will compare such aspects of the four investigated technologies.
These solutions are low-powered and use narrow frequency bands to transmit data over long distances.
First I will describe their operation and theoretical limits, then I will show examples about applying them in a real use-case.
Next I will analyze their latency and the throughput in detail using measurements, and describe the measurement arrangements used to obtain these.
In the end I will compare them using these results and make recommendations about which ones should be used in different scenarios.
