The smaller the distance value increment, the more detailed information view terrain changes. Select menu terrain data, select the menu operation, generate a profile. Fill nominal data site A and site B on the menu summary.

Select Close and press the ok button.įigure 3.4 Geographic Setting the defaultįigure 3.7 Terrain data base using the SRTM As a way to display the terrain conditions of a point to point is as follows: 1. Find the folder where the SRTM maps are stored, and select Open. Select the type of digital map on SRTM primarynya, then click the primary setup. Configure menu, sub menu terrain data base. Select the UTM grid coordinate system and the second 0:01 nearest second format. Select the WGS 1984 datum, elipsoid WGS 84, and the Southern Hemisphere latitude, longitude eastern Hemisphere. Select the terrain data menu, configure the menu the default geographic sub-menu. In summary the menu needed to fill the nominal site location data and other general information. So every site needs to know the coordinates of the nominal value before.

The main parameters that need gives a chance is the geographic location of site A and site B. Before pathloss can use these data, several parameters must be set first. Select the folder where the files are stored SRTM. Select the file menu, sub menu HDR-BIL-BLW 5. Select the primary database, content with the choice of available digital maps (in this case is the map SRTM) 3. 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).
