Radio frequency electromagnetic field compliance assessment of multi-band and MIMO equipped radio base stations

Resumen El creciente número de estaciones base de telefonía móvil celular alrededor de sectores residenciales o tránsito de personas, causa preocupación en la comunidad sobre si la radiación de campos electromagnéticos puedan causar riesgos en la salud. Internacionalmente existen estándares que establecen límites a las diversas fuentes de campos electromagnéticos para garantizar que se minimizan los riesgos en la salud. Cada país adopta dentro de su legislación algún estándar o recomendación y exige su cumplimiento a los operadores de estaciones de telecomunicaciones, por ejemplo en Colombia rige el decreto 195 de 2005. El artículo presenta una evaluación, basados en mediciones técnicas en el 2010, para obtener los niveles de exposición a campos electromagnéticos generados por las antenas instaladas en las estaciones base de telefonía móvil. Luego aparece el procedimiento general de mediciones, donde incluye el plan ejecutorial de mediciones, la configuración de la instrumentación y la caracterización de los lugares y puntos de medición. Por último, los resultados medidos en algunos lugares, donde las antenas de transmisión cumplían con la normativa adoptada en Colombia. Palabras Clave: Exposición a campos Electromagnéticos, Estaciones base de Telefonía móvil celular, Mediciones de banda angosta. Abstract The growth of installations of transmitting antennas on base stations surrounding residential spaces or person traffic causes concerns in the community, about whether the radiation of electromagnetic fields of transmitting antennas in mobile base station can generate health risk. Over the world, there are standards that establish maximum levels permitted to different electromagnetic field sources to accomplish security ranges for health risks. Each country adopts in their legislation some international standard and requires to telecommunication operators stations for its compliance. In Colombian, the decree 195 of 2005 is still valid. This article shows an assessment, based on technical measurements developed in 2010, to acquire the electromagnetic field exposure levels generated by transmitting antennas installed on Mobile Base Station. This assessment includes the measurement system procedure: plan of measurement, instrumental configuration, and characterization of measurement places. Finally, here presents the measured results in some places, which exposure levels satisfied the adopted legislation in Colombia. Keywords: Electromagnetic Field Exposure, Mobile Base Stations, Narrowband Measurement.

Political Narratives

There are widespread uses of radio frequency information technology (RADFIT) including applications related to communications, security, big data, military, transportation, space exploration, oceanography, agriculture, medical sciences, and more. Regulation of RADFIT is challenging and controversial as agencies and stakeholders struggle to balance benefits and costs. This powerful and invisible technology has the capacity to achieve breakthrough solutions by utilizing electromagnetic fields to collect, analyze, and transmit data, or to enact stimuli to create interventions for machines or living matter. However, the prevalence of RF base stations and electromagnetic fields has altered the environment and results in unintended absorption by human subjects. The public policy and politics of RADFIT, including the processes for base site installation and acceptable levels of absorption, have come to the forefront of discourse. This chapter discusses the political narratives that dictate public policy stances on the issue, bureaucratic considerations, and the response by communities.
