Millimeter waves channel measurements and path loss models
2012 IEEE International Conference on Communications (ICC), 2012This paper describes a measurement campaign performed in a modern building at the University of L'Aquila, Italy. Measurements are taken for two large bands around 60 GHz, i.e. 54–59 and 61–66 GHz. The channel probe is an ultrawideband (UWB) PN-sequence signal having a bandwidth of 1.2 GHz, which is up-converted to the 60 GHz band and finely tuned in ...

Path Loss Model for UAV-Assisted RFET
IEEE Communications Letters, 2018In this letter, we develop channel models for unmanned aerial vehicle-aided air-to-ground (AtG) radio frequency energy transfer (RFET). AtG path loss plays a key role in RFET-based recharging of field nodes. Representative field environments consist of different types of built-up areas, namely, suburban, urban, dense urban, urban high-rise, and rural ...

Adaptive Path-loss Model-based Indoor Localization
2008 Second International Conference on Electrical Engineering, 2008In this paper, we present new received signal strength (RSS)-based indoor localization system. In indoor environment, it is not desirable to use a theoretical signal propagation path-loss model. The signal propagation is severally affected by surrounded object, especially metallic object. In order to cope with this problem, we introduce a new path-loss

Low-cost wireless devices often rely on the log-distance path loss model for determining the distance between two devices based on radio signal strength. The log-distance path loss model relies on a properly determined path-loss exponent to produce accurate results; however, this variable can be difficult to obtain or estimate accurately, especially ...

A new method for path-loss modeling
International Journal of Microwave and Wireless Technologies, 2019AbstractIn this paper, a new path-loss model for electromagnetic wave in an indoor multipath environment is proposed based on matching coefficient, polarization matching factor, and normalized field intensity direction function. This model is called the Friis-extension (Friis-EXT) model, because it operates as the Friis model under certain conditions ...

Bounding the error of path loss models
2011 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2011In this paper we analyze the efficacy of basic path loss models at predicting median path loss in urban environments. We attempt to bound the practical error of these models and look at how they may hinder practical wireless applications, and in particular dynamic spectrum access networks.

Path Loss Models for Wireless Cardiac RF Communication
IEEE Antennas and Wireless Propagation Letters, 2021In this letter, we propose fundamental path loss (PL) models which play vital roles in promoting the intraheart communication system design of future deeply implanted leadless pacemakers inside the cardiac chambers. Initially, employing a plane wave approach yields the attenuation of the electric field in homogeneous heart tissue, while a modified ...

Path Loss Modeling for Outdoor UWB Channels
2018 IEEE 4th International Symposium in Robotics and Manufacturing Automation (ROMA), 2018In this paper, path loss has been analyzed and modeled based on the results obtained from an outdoor Ultrawideband (UWB) channel measurement. The measured channel is time varying and has the sparsity behavior, where most of the channel elements are zeros.

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 ...
