Channel properties influence the development of wireless communication systems. Unlike wired channels that are stationary and predictable, radio channels are extremely random and don’t offer easy analysis. A Radio Propagation Model (RPM), also known as the Radio Wave Propagation Model (RWPM), is an empirical mathematical formulation for the characterization of radio wave propagation as a functi...

A stochastic radio channel model (SRCM) for broadband indoor mobile systems operating at 5.2 and 17 GHz has been derived within the ACTS project AC085 Magic WAND. The SRCM was designed to accurately describe the time, frequency, direction, and polarization dispersive characteristic of real radio channels because these effects are important for the design of advanced receiver structures incorpor...

WLANs are nowadays at the top of the mass market networks technologies. They are essentially implemented indoors, where the traditional planning tools are not yet focused. In spite of the concern to improve the radio planning quality, the existing propagation models can still be sharpened for better outcomes, mainly in large buildings. A new propagation model is proposed and evaluated with meas...

This paper describes an efficient urban outdoor and indoor wave propagation model that supports receiver performance and coverage analyses as well as system effectiveness analyses within urban canyon environments described in the Compact Terrain Database (CTDB) format. The model has been used to support Joint MEASURE based analyses of GPS III performance/coverage within a typical urban environm...

The concept of wave propagation and the interaction of waves with matter is pivotal in many fields of physics and engineering (e. g. radio transmission, optics, sound propagation, transmission of information in waveguides...). Therefore wave propagation plays a central role in teaching physics, electrical engineering, information technology etc. from the undergraduate level (undergratuate engin...

Millimeter-wave (mm-wave) radios have been gaining interest as one of the strong enabling physical layer technologies for the fifth-generation (5G) mobile and backhaul access. This paper aims at clarifying possible roles of the mm-wave radios in the 5G development and performing comprehensive literature survey on the radio channel modeling for the feasibility study of a radio link. Emphasis in ...

This letter provides a comparison of indoor radio propagation measurements and corresponding channel statistics at 28, 73, 140 GHz, based on extensive from 2014–2020 in an office environment. Side-by-side comparisons characteristics (e.g., large-scale path loss multipath time dispersion) across wide range frequencies the low millimeter wave band 28 GHz to sub-THz illustrate key similarities dif...
