Long Range Low Power Wide Area Network (LoRa LPWAN) technology is unique and remarkable technology because of its long-range coverage, low power consumption and low cost system architecture. These features have allowed Lora LPWAN to become a favorable option for performing communication in most of IoT wireless applications. In this paper, the foliage effect has been studied in terms of attenuation and its overall contribution to the path-loss and link budget calculations.

Abstract:
ISO 9613-2 provides a propagation model in which shielding by walls can be predicted. Originally, the ISO 9613-2 was designed to predict sound propagation for industrial noise. The typical propagation distance for industrial noise is usually a few hundred meters at most; for some noise types as shooting noise, much larger distances are often relevant. Due to the great acceptance of the ISO 9613-2, the foliage attenuation of the ISO 9613-2 is also used to predict the attenuation of forest stands. However, it turned out that the foliage model of ISO 9613-2 underestimates attenuation values at la

Abstract:
As fixed wireless access (FWA) is still envisioned as a reasonable way to achieve communications links, foliage attenuation becomes an important wireless channel impairment in the millimeter-wave bandwidth. Foliage is modeled in the radiative transfer equation as a medium of random scatterers. However, other phenomena in the wireless channel may also occur. In this work, vegetation attenuation measurements are presented for a single tree alley for 26–32 GHz. The results show that vegetation loss increases significantly after the second tree in the alley. Measurement-based foliage losses are co

This is a first attempt to analyse species-specific light attenuation in mixed boreal forests created by shoot-level 3D tree models. The models are configurations of real individual Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth.) trees grown in mixed-forest stands. We study species-specific differences in radiation transmission by using the ray-casting method. Light transmission was found to be higher in dense birch-dominated stands compared with dense pine-dominated stands because of the higher total foliage area and the higher location of foliage in the pine canopy.

Abstract:
A new propagation model is proposed for estimating the attenuation of wireless communication signals in woodland environments. After rainfall or snowfall, the components of the woodland area become moist which degrades the received signal level. To take this into account, the model considers wet/dry states of the foliage, and its dependency on the operating frequency. The parameters of the propagation loss model are optimized using the least squares method. To demonstrate the validity and usefulness of the model, computed results are compared with measured data where excellent matching is obse

Biomass production in barley is determined by the amount of solar radiation absorbed by the foliage (Gallagher & Biscoe, 1978). As incident irradiance per unit area varies little between neighbouring sites and seasons in the cereal growing areas of the U.K. (Monteith, 1978), biomass production will largely be governed by the size of the canopy, the orientation of canopy constituents and the efficiency of conversion of absorbed radiation into dry matter (Green, 1984).

Abstract:
This paper aims to elucidate the clear visibility of attenuating seismic waves (SWs) with forest trees as natural metamaterials known as forest metamaterials (FMs) arranged in a periodic pattern around the protected area. In analyzing the changeability of the FM models, five distinct cases of “metawall” configurations were considered. Numerical simulations were conducted to study the characteristics of bandgaps (BGs) and vibration modes for each model. The finite element method (FEM) was used to illustrate the generation of BGs in low frequency ranges. The commercial finite element code COMSOL

Abstract:
Discussions on research directions towards systems beyond 5G/6G have started. One of the potential elements of future mobile and wireless systems are new radio systems in the (sub)-Terahertz domain above 100 GHz for communication and sensing purposes. This paper is investigating potentially available frequency bands based on the ITU Radio Regulation, basic propagation conditions above 100 GHz including the different additional path loss contributions on top of distance dependent path loss such as atmospheric and rain attenuation, foliage and wall penetration loss. The impact on system performa

Abstract:
ABSTRACT Fruit growing is an activity of great relevance for agribusiness in Brazil, with emphasis on guava. However, water deficiency is one of the limiting factors for plant productivity, so the use of phytohormones such as salicylic acid has been employed as a strategy to mitigate the effects of water deficit. The objective of this study was to evaluate the foliar application of salicylic acid as an attenuator of water deficit in guava genetic materials. The experimental design adopted was randomized blocks, in a 2 × 2 × 5 factorial scheme, considering two water regimes (irrigation depths e

Abstract:
Abstract The Precambrian bimodal Pyhäsalmi Zn-Cu-Ag-Au VMS deposit in the Svecofennian domain of Finland has undergone various degrees of metamorphism and deformation, which have altered the composition and texture of the minerals, resulting in sulfide remobilization. However, studies on metamorphism and its influence on the ore mineral remobilization in the Pyhäsalmi region are lacking. Our study provides insights into the remobilization history of ore minerals during polyphase deformational and metamorphic events in the deposit halo region by integrating mineralogical, textural, mineral chem
