An accurate measurement-based power consumption model for LTE uplink transmissions

In this poster the results of an accurate, measurement-based power consumption profiling of Long Term Evolution (LTE) User Equipment (UE) are presented together with concrete model parameter sets for four different most recent LTE data sticks and one LTE smart phone. In contrast to existing power consumption models for cellular devices, the model presented in this poster allows for a precise quantification of energy supply requirements depending on the LTE uplink data transmission power, the device type and the carrier frequency. This knowledge can be for example applied for the suitable dimensioning of batteries and energy harvesting devices in the context of LTE-based wireless sensor networks. I. MOTIVATION The battery lifetime is one of the most important perfor- mance parameters for customers. Also in the context of LTE- enabled remote sensing, energy consumption is a topic of major importance. The communication activities -in particular the uplink transmissions- are one of the major drivers of the overall power consumption. The important relationship between the uplink transmission power P Tx (dBm) and the overall power consumption of the UE ¯ P (W) has however not been sufficiently addressed for LTE so far. Especially for
