    • A method and apparatus implement network planning in a radio system in a desired area. To determine transmitter coverage, a vector map describing the surroundings of the transmitter and containing a description of buildings and surfaces reflecting radio waves in the area is used. The transmitter signal strength is measured at points of a desired area. A subset is selected among the points, path attenuation is determined between all subset points using a ray tracing method, and the calculated values are stored in a memory. When performing network planning, a transmitter and a receiver are located at the points in the areas; a given number of the most significant signal paths among the possible signal propagation paths between the transmitter and the receiver is searched for using the values stored in the memory, and the transmitter signal strength is determined at the receipt location point using the ray tracing method.
    • 一种方法和装置在期望的区域中的无线电系统中实现网络规划。 为了确定发射机覆盖范围,使用描述发射机周围的矢量图,并且包含反映该区域中的无线电波的建筑物和表面的描述。 在所需区域的点处测量发射机信号强度。 在这些点中选择一个子集,使用光线跟踪方法在所有子集点之间确定路径衰减,并将计算的值存储在存储器中。 执行网络规划时,发射机和接收机位于该区域的各点; 使用存储在存储器中的值来搜索发射机和接收机之间的可能的信号传播路径中给定数量的最重要的信号路径,并且使用光线跟踪方法在接收位置点确定发射机信号强度。

    • A method and apparatus for determining path attenuation of radio waves in a radio system, in which at least a two-dimensional vector map describing the environment of a base station is used for determining the coverage area of the base station of the system, and in which the strength of the emission of a transmitter is determined at various points in the environment. The invention is implemented by calculating from the base stations environment described by the vector map a polygon area to which radio waves can propagate both directly and by means of diffraction and reflections, by estimating the strength of the emission of the transmitter at each location point of the transmitter to be examined in the polygon area determined by calculation, and by determining points of the polygon area in advance, storing the determined points in a memory, and reading the stored points from the memory for calculating the polygon area for different location points of the transmitter.
