Abstract :
In this paper a new approach for the calibration of electromagnetic material parameters (permittivity) of 3D ray tracing prediction model at 2.4 GHz is presented. The calibration procedure is based on measurements of the channel impulse response using cross-correlation techniques and the 802.11b preamble. Further developments of a method, which has been published earlier, are presented. The analysis of the permittivity of different walls determined from a short measurement campaign is shown
