Outdoor-to-indoor radio propagation characteristics with 800 MHz band in an urban environment

Abstract

When an indoor coverage area is designed in mobile communication systems, it is important to estimate the received power from an outdoor base station in order to evaluate the interference level indoors. This paper evaluates outdoor-toindoor radio propagation with 800 MHz band through measurement campaigns at the lower multiple floors of some buildings in an urban environment. The evaluation result shows that propagation loss in an area close to a window does not follow the existing formula where loss is predicted in proportion to distance.

Flexible real-time MIMO channel sounder for multidimensional polarimetric parameter estimation

“…1 shows the distribution of the 1024 subcarriers per antenna, their spacing being equal to 97.66 kHz. To keep reasonable Previous published measurements on outdoor to indoor penetration into buildings are mainly related to the additional path loss, as described in [11]. In this case, the objective is to make a statistical analysis for different types of building and to propose path loss models.…”

Spatial Analysis Using Temporal Point Clouds in Advanced GIS: Methods for Ground Elevation Extraction in Slant Areas and Building Classifications

“…As the concentration of high buildings in urban areas affects local climate, it is an important element of urban fabric and required for building classifications [40,46,47]. It affects many factors of the urban environment such as the local temperature [48][49][50], shadows cast over nearby areas, microclimate change and urban heat islands [51][52][53][54], wind speed and orientation [55], energy exchange in urban areas [56], urban crime [57], mobile phone signal propagation loss [58], and urban renewal and planning [59]. However, studies on the spatial distribution patterns of building height remain relatively scarce [59].…”
