Measuring Power Consumption of LTE User Equipment

Application Notes

If you are designing smartphone chipsets or operating a mobile network, you need to determine how certain parameters affect a specific smartphone’s power consumption and figure out how to adjust the parameters to improve battery life. In this application note we show how to use the Keysight Technologies, Inc. E6621A PXT wireless communications test set and the Keysight N6705B DC power analyzer to establish a power consumption model for LTE user equipment (UE). The model is useful when you need to examine the UE battery life in system-level simulations.

 

We will explain how the Keysight equipment can be used in manual tests, but we do not discuss how to make automated tests (for example, using VEE software).

 

In this application note, we analyze smartphones adhering to the 3GPP LTE standard.
