Abstract

Some years ago the IRT developed a high resolution digital city model of Munich containing information on street widths and individual building heights. With these data and a powerful prediction model we calculated the indoor field strength for DVB-T transmitters in Munich. The IRT prediction method was intensively tested against mobile measurements in Munich, both in the VHF-range and in the 1.5-GHz-range, and proved to be reliable and accurate to predict coverage in urban areas. The IRT-method considers three-dimensional reflections at buildings and in this way, can simulate the multipath situation in the urban area quite well. With some modifications, the method can also be used for indoor coverage predictions. Based on these predictions, the portable indoor reception of the DVB-T transmitters is examined and the necessary transmitter power for city-wide indoor coverage can be derived. The results are also used to test the applicability of a much more simple prediction using rather coarse ground cover information instead of high resolution building data.

慕尼黑DVB-T发射机的室内覆盖

几年前，IRT开发了慕尼黑的高分辨率数字城市模型，其中包含街道宽度和单个建筑高度的信息。利用这些数据和一个强大的预测模型，我们计算了慕尼黑DVB-T发射机的室内场强。IRT预测方法针对慕尼黑的移动测量进行了密集测试，包括甚高频范围和1.5 ghz范围，并证明了预测城市地区覆盖范围的可靠性和准确性。irt方法考虑了建筑物的三维反射，因此可以很好地模拟城市地区的多路径情况。经过一些修改，该方法也可用于室内覆盖预测。基于这些预测，对便携式DVB-T发射机的室内接收情况进行了研究，并得出了城市范围内覆盖所需的发射机功率。这些结果还被用来测试一个更简单的预测的适用性，该预测使用相当粗糙的地面覆盖信息而不是高分辨率的建筑数据。
