RIS para Mejorar la Conectividad Inalámbrica en Bogotá

Abstract

Electromagnetic waves used in mobile services and next-generation networks face significant propagation constraints in urban environments due to high attenuation and limited building penetration. In cities, these limitations are compounded by sparse, antenna density, spectrum congestion, and geographic factors, leading to areas of poor connectivity and deepening the digital divide. This study examines connectivity quality in Bogotá by analyzing data sources such as user-reported reception and proposes the use of Reconfigurable Intelligent Surfaces (RIS) to create intelligent radio environments, drawing on the predominant literature on this technology. RIS are programmable metasurfaces capable of manipulating electromagnetic waves to increase information capacity and optimize the wireless channel. We outline potential deployment scenarios and the challenges relative to traditional designs currently implemented in the capital.
