Influence of Noise-Limited Censored Path Loss on Model Fitting and Path Loss-Based Positioning [PDF]

open access: yesSensors, 2021
Positioning is considered one of the key features in various novel industry verticals in future radio systems. Since path loss (PL) or received signal strength-based measurements are widely available in the majority of wireless standards, PL-based ...

Modeling In vivo Wireless Path Loss [PDF]

open access: yes2014 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-Bio2014), 2014
Our long-term research goal is to model the in vivo wireless channel. As a first step towards this goal, in this paper we performed in vivo path loss measurements at 2.4GHz and make a comparison with free space path loss.

Path loss model for wireless applications at 3500 MHz [PDF]

open access: yes2006 IEEE Antennas and Propagation Society International Symposium, 2006
The propagation measurements for fixed wireless systems operating at 3.5 GHz are analysed and discussed. A statistical path loss model for a suburban Belgian environment is proposed and different receiver heights are analysed. The path loss exponent depends upon the receiver height.

60 GHz Path Loss Modelling Inside Ships [PDF]

open access: yes2020 14th European Conference on Antennas and Propagation (EuCAP), 2020
This paper presents the results of a mmWave channel sounding campaign in a bulk carrier vessel. Using the Terragraph channel sounder, we measured path loss at 60.48 GHz for different separations between the transmit and receiving nodes in the engine room and steering control room of the vessel.

FSO Path Loss Model Based on the Visibility

open access: yesIEEE Photonics Journal, 2022
Free-space optics (FSO) is attracting renewed attention in the frame of 5G, which demands wireless backhauling technologies with extremely high data rates over distances up to a few kilometers. Link availability is a FSO well-known issue due to the large

Path loss models based on stochastic rays [PDF]

open access: yesIET Microwaves, Antennas & Propagation, 2007
In this paper, two-dimensional percolation lattices are applied to describe wireless propagation environment, and stochastic rays are employed to model the trajectories of radio waves. We first derive the probability that a stochastic ray undergoes certain number of collisions at a specific spatial location.
