Propagation path loss models for mobile communication
Proceedings of 21st International Conference Radioelektronika 2011, 2011Signal propagation and path losses are the key elements of wireless network design. This paper describes tuning process of empirical propagation path loss models for typical environments (urban, suburban, open areas). The Hata based models were compared with data measured in Brno. Model corrections were suggested and tested for GSM frequency band.

Outdoor-to-indoor path loss modeling at 10.1 GHz
2016 10th European Conference on Antennas and Propagation (EuCAP), 2016This paper presents a grazing angle dependent outdoor-to-indoor (O2I) path loss model at 10.1 GHz for a glass and a concrete wall. The COST 231 O2I path loss model is used as a baseline in model creation. The parameters for the model are derived from radio channel measurements performed with a vector network analyzer and a single-input single-output ...

Lee's model (cellular radio path loss prediction)
[1992 Proceedings] Vehicular Technology Society 42nd VTS Conference - Frontiers of Technology, 2003Lee's model is used to predict the local-mean of a received signal along a mobile path where the mobile unit travels. The standard derivation of prediction error by comparing the predicted values with the measured data is approximately 2-3 dB. The model is simple to implement and has a theory to back it. >

Propagation Path Loss Models for Parking Buildings
2005 5th International Conference on Information Communications & Signal Processing, 2006This paper proposes a method to predict path loss in parking buildings. We performed measurements in two different of parking buildings at a frequency of 1.8 GHz and proposed new upper- and lower-bound models. The actual breakpoint distance was shorter than theoretical one because of the effective floor height due to cars.

Modeling Path Loss in Confined Animal Feeding Operations
2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008Wireless sensor networking technology has great potential to advance monitoring of animal environments. Recent applications are very limited due to a lack in understanding of the performance of wireless sensors in large-scale, concentrated, and confined animal feeding operations.

Empirical Path Loss Models Optimization for Mobile Communication
2018 IEEE 5th International Congress on Information Science and Technology (CiSt), 2018In this paper, the most widely used empirical path loss models are compared to real data; the most appropriate one (COST-231) has been optimized using three different algorithms to fit measured data for mobile communication system. The performance of the adjusted Cost-231 model obtained by the proposed methods is then compared to the experimental data.

Frequency analysis of path loss models on WIMAX
2011 3rd Computer Science and Electronic Engineering Conference (CEEC), 2011WIMAX signal throughput and area coverage range are the most important factors that will affect the quality of broadband access services in mobile systems. This paper presents a comprehensive study of frequency analysis for path loss on mobile WIMAX presented to achieve large throughput and wide coverage to a big number of users.
