The increasing dependence of human beings on technology has not only made ICT a growing power consumer, but also a rising contributor to the adverse effects of global climate change. In light of the growing power consumption by ICT, accurate measurement techniques are required since leaders cannot manage what cannot be measured. One of the emerging power measurement techniques is via the use of...

The measurement of the dynamic power consumption is an important task in the field of energy harvesting regarding the characterization and optimization of low power systems. This paper reports on the development and characterization of a computer-controlled measurement system for the measurement of the dynamic current consumption of low power systems in a range from 100 nA to 100 μA, with a tim...

Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...
