NB-IoT vs. LTE-M: Measurement Data of the Energy Consumption of LPWAN Technologies

NB-IoT vs. LTE-M: Measurement Data of the Energy Consumption of LPWAN Technologies

This dataset contains the raw energy measurements as well as R scripts to reproduce the energy consumption plot for the corresponding paper.

Each .csv file contains a specific set of measurements and we provide a script to read, process and plot the contained data.

Figure 3

Mean energy consumption of the different phases for Authentication for NB-IoT and LTE-M.

Due to the fact that the duration of Idle Connected in the measurement scripts was 30 seconds and 60 seconds for Idle Not Connected, the D-value and the mean power consumption are divided by 2.

Figure 4

Mean energy consumption of the different phases for Data Connection and Download for NB-IoT and LTE-M for 1KB of data in HTTP.

The delay between the measurements for Figure 4 were all 30 seconds long, but the identified Standby and Idle phases have different lengths. Therefore, the Idle phase values for both access technologies have been normalized and calculated for 20 seconds each.

Figure 5

Mean energy consumption of the different phases for Data Connection and Download for HTTP and MQTT for 1KB of data in NB-IoT.

In this scenario the delay between the measurements were different again. For MQTT the delay was 150 seconds and for HTTP 30 seconds. Therefore, the data during the Idle and Standby (only for MQTT) phase is normalized and calculated for 20 seconds and 10 seconds, respectively. During the MQTT Idle phase measurements, the device disconnects. This is not taken into account for the evaluation, which is why these energy values are discarded for this figure.
