Abstract
In this project a measurement of the effective radiated power (ERP) is compared to a measurement of the total radiated power (TRP). ERP is measured according to ETSI inside an anechoic chamber and TRP is measured inside a reverberation chamber. The measured TRP value is related to the ERP value via an estimated maximum directivity of the test object. The comparison is performed for three active radio units with terminal antennas at their carrier frequencies and their first five harmonic frequencies. The uncertainty of an ERP measurement according to ETSI is compared to the uncertainty of an estimation of the ERP value via the TRP measurement as proposed in the new method.
