When sites have been created, you can create one or several microwave links. To start working with point-to-point links, open the Point-to-Point item on the main menu. Figure 6. Point-to-Point main menu.

First, it is necessary to include the specification file of the equipment family that is supposed to be involved in the project.

Click on the Add a new product family button in the Point-to-Point menu to include the product family to your project. To download the product family files from our website, click on the Download product family files button, and a link will open in the browser.

We are continually updating the files with equipment parameters, but if such equipment not on our website, then first create the equipment specification file see Equipment Editor. Tx power general limits for all PtP links. Maximum Tx power for transmitters of all PtP links in this project, dBm From the general limit that is set in this menu and the limit that is set in a particular link, the most stringent limit is selected during the calculation.

Maximum EIRP for transmitters of all PtP links in this project, dBm From the general limit that is set in this menu and the limit that is set in a particular link, the most stringent limit is selected during the calculation.

To create a PtP link, click on the Create a new PtP link button at the top of the Point-to-Point menu, and the program will prompt you to select the link ends, Site A and Site B, from the sites created before. Then this link will appear in a point-to-point tree and a panel will open with its parameters. Figure 7. PtP link parameters. The required link can be selected from the list in the Point-to-Point menu or by double-clicking on it on the base map.

A path profile is a vertical sectional view of the terrain created by a plane passing through both ends of the link. The path profile includes terrain elevation data, building and tree heights, and boundaries of water bodies. Terrain elevation data m plane resolution for more details on data sources see Appendix 1.

Terrain Elevation Data. Global tree cover 1 arc sec about 30 m resolution data with information about tree heights. Global 3D buildings data from OpenStreetMap project database. All of these types of geodata are downloaded for the desired area automatically as needed; there is no need to worry about preloading the geodata.

In the created link, click the button Generate path profile. A warning dialog box will appear indicating that the path profile data will be changed. You should specify the average building floor height typically 3 m in this window. The OSM project database usually contains information about the number of floors of the buildings rather than their height in meters. Building height in the path profile will usually be based on the number of floors and floor height. You will also have to specify the height of the buildings for which OSM project database does not have information.

Such buildings will be highlighted in red in the path profile. The user can override the forest height information obtained from the Global Forest Change records and set a new value to be used in a path profile. Figure 8. Path Profile Creating Settings. Click OK, and after a couple of seconds, the information about terrain elevation and clutter characteristics along the path profile will appear in the table cells.

The view of the path profile will be displayed at the top right panel. Figure 9. Path Profile. Green: trees Orange: buildings whose height or number of floors can be found in the OpenStreetMap database Red: buildings whose height and a number of floors are missing in the OpenStreetMap database.

Terrain elevations can be edited manually in the corresponding cells of the elevation table. To edit terrain elevations for multiple cells, select the required cells and enter a new value. The new elevation will be saved to all selected cells, and the information about old elevations will be automatically removed. Only end values of this range will remain. To delete an entire row in the table, click on the triangle icon at the beginning of the row to select either a single row or multiple rows by dragging the mouse or holding the Shift key and using the up or down arrow keys and press Delete.

If you highlight a segment on the path profile by clicking and dragging the left mouse button, the segment will also be highlighted in the terrain elevation table, clutter table, and on the base map. Likewise, if you select rows in the elevation or clutter table, it will highlight the corresponding section in the path profile view and on the base map. Figure Highlighting the path profile segment.

The clutter also can be edited manually in the corresponding cells of the clutter table. The application allows you to create a path profile by manually specifying all elevations on the path. The information about forest, buildings, and water bodies can be entered based on the base maps, which you can open right in the application. Many online services allow you to view cartographic materials. They all differ in such parameters as map scale, coverage, and displayed objects.

Depending on the specific area where the link is located, you may find one or several services useful. It is also important to select a proper scale of the map.

More information about using custom base maps can be found in the application. After analyzing the basemap along the line of the path profile, you can enter a boundaries of forests, buildings, and water bodies. To do that, on the base map, right-click on the point on the link path where you want to enter the start of a clutter object segment. A context menu will open where you can select corresponding types of the segment.

When the ends of a segment are marked, a number field will appear that you must fill in to indicate forest or building height. On the path profile, the forest is highlighted in green, building in orange, and water area in blue. Table entries for clutter and water information will be created automatically.

You can delete any segment by right-clicking on it and selecting the corresponding action in the context menu that appears. Specify the beginning of the building segment on the path profile. Specify the beginning of the tree segment on the path profile. Specify the beginning of the water segment on the path profile. The following must be observed when creating a path profile manually:.

The first elevation point must have a zero distance. The path profile must have at least two points. A clutter object must not extend beyond the last terrain point. Adjust the link profile to allow for terrain height variance, obstructions and reflection. See Adjusting Link Profiles. Confirm that the link will perform to an acceptable level, measured by the Throughput and Availability values in the Performance Summary section of the Link Page. Export and report project, site and link data.

Created using Sphinx 1. If the file with the necessary equipment was not included in the supplied set, the program provides a tool, Equipment Editor, with which the user can prepare the specification file. To start the equipment editor, click on the Equipment Editor icon on the top toolbar. Figure 4. Equipment Editor. Family Name. Family Info.

Fill in all the products in the Family. Fill in all the frequency bands which are available for the Family. Fill in all the Modulation and Coding which are available for the Family. After filling in, click OK, this panel will close, and the entered information will appear in the Products, Frequency Bands, as well as in the Modulation and Coding table of the main panel of the Equipment Editor.

Select the type of equipment family - Point-to-Multipoint or Point-to-Point. For the Point-to-Point family, fill in the information about the maximum available branching configuration, available branching types, available diversity options, and the type of adaptive equalizer parameters. All of this information will be taken into account in the future when configuring PtP microwave links based on this product family.

If an antenna is built into the equipment, as is often the case for PtMP base and subscriber stations, select the Integrated Antenna, enter its gain, and download the antenna pattern file in MSI format.

If one picture is used for all products, then indicate this using the checkbox in the upper right corner; this will significantly reduce the size of the file with the specification. Fill in the columns Channel bitrate, Tx Power, and Rx threshold for each modulation type. For convenience and reducing time when filling out specifications, several tools are provided here, and copying and pasting groups of cells from spreadsheets are also supported. This tool can be used for an approximate assessment of threshold sensitivity when accurate data is not available for all bandwidths.

The tool is based on the fact that the threshold sensitivity of the receiver decreases in proportion to the increase in bandwidth. For example, when the bandwidth is doubled, the threshold sensitivity decreases by 3 dB.
