A Practical Radiosity Method for Predicting Transmission Loss in Urban Environments
نویسندگان
چکیده
The ability to predict transmission loss or field strength distribution is crucial for determining coverage in planning personal communication systems. This paper presents a practical method to accurately predict entire average transmission loss distribution in complicated urban environments. The method uses a 3D propagation model based on radiosity and a simplified city information database including surfaces of roads and building groups. Narrowband validation measurements with line-of-sight (LOS) and non-line-of-sight (NLOS) cases at 1800MHz give excellent agreement in urban environments.

A Tool for Power-Density Prediction of Radio Propagation in Urban Environments
The ability to predict transmission loss or field strength distribution is crucial for determining coverage in planning personal communication systems. Previous transmission loss prediction methods have considered specular reflection and diffraction of electromagnetic waves by and over buildings between the base station and the mobile terminals. These phenomena are of great importance in urban ...
متن کاملVirtual Geographic Simulation of Light Distribution within Three-Dimensional Plant Canopy Models
Virtual geographic environments (VGEs) have been regarded as an important new means of simulating, analyzing, and understanding complex geological processes. Plants and light are major components of the geographic environment. Light is a critical factor that affects ecological systems. In this study, we focused on simulating light transmission and distribution within a three-dimensional plant c...
متن کاملUrban expansion as a driver of biodiversity loss: Integrating biodiversity in urban planning in African context
Africa has high biodiversity and is rapidly urbanizing. However, there is limited understanding of how urban expansion in Africa is likely to affect its habitats and biodiversity. Little urban ecological research has been done in Africa. This study needs to think ahead as Africa move into the “urban age” it is critical to inform the public on the importance of urban environment...
متن کاملReflected and Transmitted Irradiance from Area Sources Using Vertex Tracing
Computing irradiance analytically from polygonal luminaires in polygonal environments has proven effective for direct lighting applications in diffuse radiosity environments. Methods for analytic integration have traditionally used edge-based solutions to the irradiance integral; our previous work presented a vertex-based analytic solution, allowing irradiance to be computed incrementally by ra...
متن کاملA directional-based branches current method for transmission loss allocation in the pool-based electricity market
This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...
