Base station radiations

In this paper, we present a configuration of a wideband MIMO antenna array for 5G terminals. The single-element antenna has compact size, dual polarization, wide operating bandwidth covering the 5G N78 frequency band, and high isolation between the two input ports (>40 dB).

Radiation portal monitors (RPMs) are now stationed at strategic areas (airports, ports, etc.) to identify the illegal transportation of radioactive sources and nuclear items. RPMs are typically fitted with a PVT detector with a high recording efficiency. Radioisotope identification from the gamma spectrum acquired on this detector is normally not regarded due to the low resolution.

The paper concentrates on build these types of beam, and also proves the Signal to Interference and Noise Ratio (SINR) to be higher than the traditional case without using anti-interference radiation from other BS stations.

In this study, we evaluated the Himawari-8 radiation product, named AMATERASS, provided by solar radiation consortium under Japan Science and Technology Agency (JST), Strategic Creation Research Promotion Project/Terrestrial Energy Estimation and Demand Data Analyzes (CREST/TEEDDA) using observations recorded at 5 stations in different regions of Viet Nam. The result showed good agreement between satellite estimation and observed data with high correlation of range 0.92- 0.94, and better in clear-sky episodes.

This paper presents the preliminary analysis of ground-based measurements solar data in Umlazi, South Africa. From this analysis, data statistics and statistic models for the global horizontal irradiance (GHI), the direct horizontal irradiance (DHI) and the ultraviolet radiations (UVR) are obtained for Durban and surrounding areas. Those results can be used in the design and analysis of solar systems and can also be used as referential parameters for further assessment of solar energy potentials for those areas.

Due to increase in telecommunication facilities, Ujjain, simple and holy city is crowded by number of Mobile Base Stations. Also mobile phone users are also increasing day by day due to its excessive use and dependence. The aim of the present study is to investigate the association of use of mobile phones and radio frequency exposure to base stations with fatigue, headache, dizziness, tension and sleep disturbance etc. in adolescents and adults population of Ujjain and to provide an outcome which can deal with health and social awareness.

The reference evapotranspiration (ET0) of Morena station was estimated using multiple linear regression (MLR), The climatological data such as maximum temperatures, minimum temperature, mean relative humidity, wind speed and solar radiation were collected for the morena station and district of Madhya Pradesh state of India for the period of thirty years and the missing value of that data series was also determine using SPSS-21 software. The observed reference evapotranspiration (ET0) values were estimated using the Penman monteith (FAO56-PM) equation.

Mobile phones are convenient and frequently invaluable, yet exposure to their electromagnetic radiation is invisible. Therefore, any danger this exposure poses may be easily dismissed. • Exposure is long-term and its effects on the body, particularly its electrical organ, the brain, are compounded by numerous other simultaneous long-term exposures including continuous waves from radio and TV transmitter towers, cordless phone base stations, power lines, and wireless/WiFi computing devices....

Licensed spectrum wireless service providers can experience difficulties deploying wireless service through traditional base stations for a variety of reasons. These include zoning restrictions, high cost of site acquisition, limited revenue-generating potential to justify deployment of a dedicated site, and technical reasons such as extended feeder cable runs.
