This report presents a laboratory-based characterization of Long Term Evolution (LTE) User Equipment (UE) emissions under closed-loop power control, building on our prior work (NIST TN 2069), which assessed the impact of a large number of factors aff

The authors present a test method for quantifying and reducing systematic errors arising from antenna proximity to lossy objects in over-the-air performance testing of lossy large-form-factor wireless devices. The method determines the extent to whic

The strength of an electromagnetic plane wave incident in the free field can be characterized in terms of power output by an idealized isotropic antenna probe. We refer to the parameter as equivalent isotropic incident power (EIIP), though it lacks a
