Select Configure menu, select the sub menu terrain data base. The process to enter the terrain data is as follows: 1. ![]() ![]() In addition to using a digital map, pathloss 4.0 can also receive input manually regional topology is based on field surveys and study maps. Some digital map that can be used, among others Gtopo 30 and SRTM. ![]() Where the division is divided into areas A through Q.įigure 3.1 Regional Distribution According Rain Pn.837 ITU-R-1 On this rainy region following the distribution according to ITU-R Pn.837-1 which is divided into areas A through Q.įigure 3.2 Data base Rain zoning of pathloss 4.0ģ.2 Topology geography (Terrain view) Pathloss 4.0 supports the use of digital files to show the topology something. Usually recommendations for rain area is often used by ITU-R Pn.837-1. Before the implementation of network, designers networks must be able to predict the possibility that will occur in loss-free channel. Then rain units are expressed in millimeters per hour. Before discussing the method of calculation of these losses is necessary to a discussion of information about the rain issue. The addition of this signal attenuation occurs at a total loss of transmission lines that use the media not guided ( used air media).
