Applied for the first time to mobile radio propagation modeling at the beginning of the nineties, ray tracing is now living a second youth. It is probably the best model to assist in the design and planning of future short-range, millimeter-wave wire

An experimental evaluation of the possible effects produced on wireless links operating at 2.4 GHz by snow and ice accumulation over the antennas is presented. The measurement outcomes show that an additional loss increasing with the dimension of the

Environmental effects may seriously threaten the performance of UHF RFID systems and reduce the rate of successful reading; many applications aiming at the so-called item-level tagging (ILT) can be therefore compromised. In order to preserve the reli

The performance of UHF-RFID systems are particularly exposed to environmental effects, such as multipath propagation and electromagnetic coupling. This sensitivity to the electromagnetic properties of the environment is peculiar of systems operating

An experimental work aimed at assessing the outdoor-to-indoor propagation losses at 169 MHz is described in this paper. The building penetration loss, often considered as an additional constant value to be added to propagation losses in previous stud

A novel statistical model for over rooftop (ORT) propagation in an urban environment is presented in this paper. The proposed algorithm is based on an automatic extraction of the relevant environment parameters from the urban map. These parameters ar

Field prediction is an essential component of the planning process of cellular radio systems. This task is particularly time- and money-consuming in the urban environment, where cell size is of the order of a few hundred meters, and the influence of

Advanced radio transmission and antenna techniques, such as MIMO, directive-antennas and beamforming have recently been proposed for high-speed communication systems. In this work we study the Power-Angular-Distribution for different receivers locati

The choice of a given propagation model has a major impact on the accuracy and effectiveness of cellular planning, especially in an urban environment, where a higher degree of detail is required. Rigorous models, such as those based on ray optics, ar
