Step Length Measurements Using the Received Signal Strength Indicator
Sensors, 2021 In this paper, portable transceivers with micro-controllers and radio frequency modules are developed to measure the received signal strength, path loss, and thus the distance between the human ankles for both indoor and outdoor environments.

Small Aircraft RF Interference Path Loss [PDF]
2007 IEEE International Symposium on Electromagnetic Compatibility, 2007 Interference to aircraft radio receivers is an increasing concern as more portable electronic devices are allowed onboard. Interference signals are attenuated as they propagate from inside the cabin to aircraft radio antennas mounted on the outside of the aircraft.

Cellular system information capacity change at higher frequencies due to propagation loss and system parameters [PDF]
, 2012 In this paper, mathematical analysis supported by computer simulation is used to study cellular system information capacity change due to propagation loss and system parameters (such as path loss exponent, shadowing and antenna height) at microwave ...

Stochastic Analysis of Non-slotted Aloha in Wireless Ad-Hoc Networks [PDF]
, 2010 In this paper we propose two analytically tractable stochastic models of non-slotted Aloha for Mobile Ad-hoc NETworks (MANETs): one model assumes a static pattern of nodes while the other assumes that the pattern of nodes varies over time.

Connectivity of confined 3D Networks with Anisotropically Radiating Nodes [PDF]
, 2013 Nodes in ad hoc networks with randomly oriented directional antenna patterns typically have fewer short links and more long links which can bridge together otherwise isolated subnetworks.

In-body path loss models for implants in heterogeneous human tissues using implantable slot dipole conformal flexible antennas [PDF]
, 2011 A wireless body area network (WBAN) consists of a wireless network with devices placed close to, attached on, or implanted into the human body. Wireless communication within a human body experiences loss in the form of attenuation and absorption.

Development of path loss model for 802.11n in large conference rooms [PDF]
, 2011 In this paper, a path loss (PL) model for 802.11n in large conference rooms is determined, based on PL measurements. The PL can be described accurately by a one-slope model with one standard deviation.

Study on 3GPP Rural Macrocell Path Loss Models for Millimeter Wave Wireless Communications
, 2017 Little research has been done to reliably model millimeter wave (mmWave) path loss in rural macrocell settings, yet, models have been hastily adopted without substantial empirical evidence.

BuildingsStructural seismic resilience is influenced by both the structural performance loss (loss) and the repair path (path). Some studies ensure the reality of path but lack accuracy of loss.
