Non-Ionizing Radiation Analysis in Close Proximity to Antenna Tower: A Case Study in Northeast Brazil
André B. F. Diniz, Vicente A. Souza, Marcio E. C. Rodrigues +3
While the amount of telecommunications services grows rapidly in the whole world, humans get potentially more exposed to Non-Ionizing Radiation (NIR) from a number of different sou…
Non-Ionizing Radiation Measurements for Trajectography Radars
J. Marcos Leal Barbosa Filho, Millena M. de M. Campos, Daniel L. Flor +4
This work presents a Non-Ionizing Radiation (NIR) measurement campaign and proposes a specific measurement method for trajectography radars. This kind of radar has a high gain narr…
Evaluation of Acoustic Noise Level and Impulsiveness Inside Vehicles in Different Traffic Conditions
Daniel Flor, Danilo Pena, Hyago Lucas Oliveira +3
Recently, the issue of sound quality inside vehicles has attracted interest from both researchers and industry alike due to health concerns and also to increase the appeal of vehic…
Solution for Interference in Hotspot Scenarios Applying Q-Learning on FFR-Based ICIC Techniques
Iago Diógenes do Rego, Vicente A. de Sousa
This work explores interference coordination techniques (inter-cell interference coordination, ICIC) based on fractional frequency reuse (FFR) as a solution for a multi-cellular sc…
Human Exposure to Non-Ionizing Radiation from Indoor Distributed Antenna System: Shopping Mall Measurement Analysis
Júlia da L. A. Silva, Vicente A. de Sousa, Marcio E. C. Rodrigues +8
It is crucial to monitor the levels of Non-Ionizing Radiation (NIR) to which the general population may be exposed and compare them to the limits defined in the current standards,…
Vertical Assessment of RF-EMF Exposure in a Building Adjacent to a Multi-Operator Shared Base Station
Ricardo Q. de F. H. Silva, Marcio E. C. Rodrigues, Fred S. R. Pinheiro +3
This paper extends a previously published proposed approach for estimating worst-case exposure scenarios in buildings using publicly available Base Station (BS) parameters, applyin…
