“…Two simple scenarios with few objects are used to assess the accuracy of the electromagnetic calculation. They were previously used in [40] and [41], where both measurements and simulated data are reported. As a third example a typical urban scenario [42] is analyzed to test both the reliability of calculations and the computational charge.…”

Abstract-High frequency methods resort to numerical ray tracing for application to complex environments. A new method based on the geometrical projection performed by a ray-congruence has been developed as a preconditioning of the ray tracing procedure. It builds a visibility tree, i.e., a database, storing information on all possible ray paths inside a scenario. The method gives a solution to a class of open problems of ray tracing techniques: ray missing, double (multiple) counting, termination criterion, calculation upgrade. Other features of the method are the multipath map and the multipath classification that allow the user to know the relevance of multipath at any point of the scenario in advance, before ray-tracing calculation.The method can be systematically applied to scenarios pertaining to different applications provided that the objects belong to the class of polyhedrons. Reflected and diffracted contributions in a scene are modelled as secondary sources which are handled with an off-line electromagnetic field calculation.Numerical analysis is provided showing the efficiency of the method.

“…Such measurements have already been conducted and analysed in various references, e.g. [5][6][7]. Theoretically, if the scattering environment around the receiver were perfectly conducting, there would be no obstacles to rely on such obtained results when a "last-mile" multipath propagation is considered.…”

The paper is intended to explore a possibility to apply scaled radio measurements in estimation of real multipath propagation channel characteristics, such as impulse responses and corresponding autocorrelation functions. Naturally, the influence of estimatedpermittivity error on usability ofsuch a procedure is supposed to be the main problem. In order to provide an insight in this issue, ray-tracing simulations oftwo typical multipath scenarios have been compared with corresponding scaled measurements. It has been concluded that, in order for a scaled measurement to be reliable, the permittivity issue with reference to the considered radio environment must be properly addressed

“…However, the literature concerning scaled measurements for characterizing coherent wave propagation is scarce. In [7] and [8], a fixed scaled system, operating at 25 GHz, is reported for measuring wave transmission over simple two-dimensional (2-D) rectangular cylinders. In this paper, a sophisticated millimeter-wave scaled propagation measurement system (SPMS), the concept of which we presented in [9], is designed to measure all desired channel parameters over a realistic scaled urban environment.…”

Abstract-In this paper, a scaled measurement system designed for wireless channel characterization is proposed and discussed, and experimental results are reported. The system consists of a vector network analyzer, miniaturized -band transmitter and receiver probes, scaled buildings, and a precise computer-controlled positioner. The scaled propagation measurement system is designed to operate coherently at the 90.8-92.8-GHz band, and it provides a dynamic range of 85 dB. As the measurement wavelength in this system (=3 mm) is approximately two orders of magnitude smaller than the actual wavelength in most commercial and military wireless systems, a typical dimension of the propagation environment can be smaller than the actual environment proportionally. Hence, propagation measurements can be done very efficiently under laboratory conditions using a scaled model of a city block. This system is intended for verifying the results of wave-propagation prediction software. It can also be used to investigate scattering models for different types of buildings and complex objects, data collection for wireless communication, and many other studies such as diversity methods (frequency and polarization).Index Terms-Coplanar waveguide (CPW), millimeter wave, scaled model, subharmonic mixer, wave propagation, -band.
