Radio Propagation Measurement and Channel Modelling

Iury S. Cristiane R. It is essential to establish dominant propagation mechanisms in indoor environments to model propagation loss for 5th generation networks. This work presents, discusses and analyzes the data of measurement campaigns carried out in the 10 GHz band. These data were obtained in two different scenarios: a corridor and a laboratory. The measurement campaigns were conducted with horn-type directional antennas considering vertical, horizontal and cross-polarization modeling under line-of-sight conditions, where horizontal polarization antenna modeling is the differential of this work.

Radio propagation is the behavior of radio waves as they travel, or are propagated , from one point to another, or into various parts of the atmosphere. Several different types of propagation are used in practical radio transmission systems. Line-of-sight propagation means radio waves which travel in a straight line from the transmitting antenna to the receiving antenna. Line of sight transmission is used for medium-distance radio transmission, such as cell phones , cordless phones , walkie-talkies , wireless networks , FM radio , television broadcasting , radar , and satellite communication such as satellite television. Line-of-sight transmission on the surface of the Earth is limited to the distance to the visual horizon, which depends on the height of transmitting and receiving antennas. It is the only propagation method possible at microwave frequencies and above. At lower frequencies in the MF , LF , and VLF bands, diffraction allows radio waves to bend over hills and other obstacles, and travel beyond the horizon, following the contour of the Earth.

Propagation measurements and models for wireless communications channels Abstract: The authors describe the type of signals that occur in various environments and the modeling of the propagation parameters.

Propagation models constitute a fundamental building block of wireless communications research. Before we build and operate real systems, we must understand the science of radio propagation, and develop channel models that both reflect the important propagation processes and allow a fair comparison of different systems. In the past five decades, wireless systems have gone through five generations, from supporting voice applications to enhanced mobile broadband.

Aalto University School of Electrical Engineering. Millimeter-wave mm-wave radio is attracting attention as one of the key enabling physical layer technologies for the fifth-generation 5G mobile access and backhaul. This paper aims at clarifying possible roles of mm-wave radio in the 5G development and performing a comprehensive literature survey on mm-wave radio channel modeling essential for the feasibility study. Emphasis in the literature survey is laid on grasping the typical behavior of mm-wave channels, identifying missing features in the presently available channel models for the design and evaluation of the mm-wave radio links within the 5G context, and exemplifying different channel modeling activities through analyses performed in the authors' group. As a key technological element of the mm-wave radios, reduced complexity beamforming is also addressed.

While there are numerous books describing modern wireless communication systems that contain overviews of radio propagation and radio.
