Abstract :
This paper investigates the influence of the human body on indoor measurements of radio wave path loss at 3.5 GHz and proposes a solution to improve the accuracy of measurement. The presence of the human body causes measurement errors to radio wave field strength, which is of concern for analysis. The reduction of errors due to measurement process enhances the accuracy of measurement data that is used to validate propagation models. Also, the characterisation of signal strengths at nearby-locations will be presented, which may be used as a proof to develop new propagation models that take advantage of fast calculation based on the observation of relations between geographically-related signal levels. This is also used to analyse the human body influence depending on the locations.
