Multiplicative based path loss model
International Journal of Communication Systems, 2018SummaryWe present a newly introduced multiplicative based path loss model for the wireless channel. The model verified with experimental data at 2100 MHz collected across Cyprus in 6 existing microcells in urban, suburban, and rural areas. The new method uses the multiplicative least square fitting model that relates the decibel path loss to the ...

Validation of path loss by heuristic prediction tool with path loss and RSSI measurements
2010 IEEE Antennas and Propagation Society International Symposium, 2010The characterization of path loss in indoor environments has been the subject of extensive research and many models have been proposed to make accurate predictions. Statistical models are easy to obtain when a lot of measurement data are available, but their validity is limited to the category of buildings in which the measurements are performed.

Weight Loss Management: A Path Lit Darkly
Health Education & Behavior, 1998This article reviews recent research on the prevalence and virulence of obesity as a causal risk factor for mortality and morbidity. The prevailing assumption that obesity, by itself, is a chronic disease or a primary risk factor for health is challenged.

Path loss model for crowd counting
2017 7th IEEE International Conference on Control System, Computing and Engineering (ICCSCE), 2017Crowd counting using wireless sensing relies on either participatory or non-participatory methods. In both cases, the algorithm developed would predict the number of people or their density within the area monitored, for the purpose of crowd safety and management. An alternative to such approaches is the path loss modeling. A model is proposed to count

D-band indoor path loss measurements
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014This paper presents the path loss measurements of 110 to 170 GHz indoor wireless channels. The measurements are performed in line-of-sight (LoS) and obstructed-line-of-sight (OLoS) environments. The results show that the measured path loss is in good agreement with the theoretically predicted path loss.

Wireless signal propagation path loss estimation
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014In this work, the power of the wireless interference received by the victim communication system in the spectrum-sharing scenario between two wireless communication systems is investigated. The path loss models are detailed, and simulation results are given. The interference analysis is important for successive interference mitigation processing, which

Path loss revisited using computer simulation
2009 IEEE International Conference on Systems, Man and Cybernetics, 2009In this paper, we propose a computer simulation model for the study of the large-scale effects on narrowband wireless transmission systems. The development of the path loss model is based on the ray tracing technique. This study concentrates on the first-order scattering effects, namely each multipath signal is a two-hop signal that involves a single ...

Path-loss prediction model for microcells
IEEE Transactions on Vehicular Technology, 1999Empirical path-loss formulas for microcells in low-rise and high-rise environments are established from measurements conducted in the San Francisco Bay area. Using the 1-km intercepts and slope indexes of the least square fit lines to the measurements at cellular and personal communication services (PCS) frequencies for three base station heights ...

Path-Loss Measuring Techniques and Equipment
IEEE Transactions on Communications, 1960The planning of tropospheric scatter communication systems requires precise and reliable knowledge of the path loss. This paper describes the techniques and equipment used to evaluate proposed installations. The equipment operates in the frequency range of 875 to 940 or 1650 to 1950 mc with output powers of 10 or 100 watts.

Ensembling Probabilistic Regressors for Path Loss Prediction
Proceedings of the 4th URSI Atlantic RadioScience Conference – AT-RASC 2024Machine Learning (ML) based Path Loss (PL) prediction is of great importance when designing modern communications networks. As a result of providing a framework for understanding what learning entails, probabilistic modeling has become one of the most prominent theoretical and practical methods for developing machines that acquire knowledge from ...
