Energy consumption analysis of Sub-1GHz IoT device

Integrated technological environments can be develop using information captured by wireless sensor networks. This class of networks operates for long periods of time, therefore low energy consumption devices are required. This paper measures the level of energy consumption during the communication period between two IoT-devices in sub-1GHz frequency operation without a specific native communication protocol. The analysis was made based on electric current measurements, obtained using different parameters to observe different possible cases. The device life expectancy was studied in commercial battery models. A life expectancy of device is 4.5 years in average considering several types of setups with periodical consumption.
