We have made every effort to create a user-friendly and intuitive application. However, we recommend that you spend some time reading this User Manual to get the most out of the MLinkPlanner.
About MLinkPlanner
MLinkPlanner is a powerful and user-friendly tool for designing microwave point-to-point (PtP) and point-to-multipoint (PtMP) links. MLinkPlanner was created by engineers with many years of experience in designing microwave links, from single-hop access links to high-power long-haul trunk lines.
MLinkPlanner has demonstrated its effectiveness in designing many links that are operating successfully in various climate zones and topographical conditions from plains and marshlands to highlands.
Special focus was placed on devising a convenient user interface, the incorporation of adaptable and easy-to-use link path profiles in the design process, and the automation of all key calculations.
Main Features
Fully automatic path profile generation with terrain elevation, tree height, and height of buildings based on:
-
Terrain elevation data 2-30 m plane resolution (Default DEM). For more details on data sources see Appendix 1. "Terrain Elevation Data". It is also possible to use custom DEM in GeoTIFF format with any plane resolution.
-
Global tree cover 1 arc sec (about 30 m) resolution data with information about tree height Data sources: High-Resolution Global Maps of 21st-Century Forest Cover Change Published by Hansen, Potapov, Moore, Hancher et al. Department of Geographical Sciences University of Maryland https://earthenginepartners.appspot.com and Jet Propulsion Laboratory California Institute of Technology https://landscape.jpl.nasa.gov
-
Global 3D building data from OpenStreetMap project database. Data source: Our buildings database, which synchronizes with the global OpenStreetMap database.
All of these types of geodata are automatically downloaded to the required area as needed; there is no need to worry about preloading the geodata.
Moreover, you can edit an existing path profile or create a new one manually.
The application allows you to use standard basemaps (such as OpenStreetMap, OpenTopoMap, US Topo etc.) and custom ones.
MLinkPlanner 2.0 can perform the calculation and optimization of PtP and PtMP microwave link parameters, including:
-
Path profile analysis (evaluate different clearance criteria, obstruction loss, reflection geometry)
-
Multipath fade probability prediction (Rec. ITU-R P.530-17 method; Vigants-Barnett method)
-
Rain fade estimation (Rec. ITU-R P.530-17 method; Crane method)

As in the main user menu, the program uses a multi-level tree interface. When you select one of the menu items, the corresponding panel opens next to it.
MLinkPlanner also has a context menu on the base map. You can use them to quickly perform various actions. The options for this context menu directly depends on selected main menu items.
Different layers can be displayed on the base map — sites, microwave PtP links, PtMP base and subscriber stations, PtMP coverage, various additional custom vector layers, etc. You can choose to display one of the pre-installed base maps or customize your base map, as described in the Base map Settings section.
Map navigation performs with a mouse. Use the mouse wheel to zoom the map in or out. You can also select the required zoom from the drop-down list in the toolbar.
When the map zooms into level 12 or higher, the application begins to download SRTM elevation data and tree cover data. The status bar displays the pointer’s geographic coordinates and the information about the elevation above sea level and the height of the tree canopy. Usually, loading of the necessary data sets (terrain, elevation, and tree cover) takes place in a few seconds.

Projects
MLinkPlanner project files have a *.mlp2 extension. Each file contains information about the project, including path profiles and parameters of microwave equipment. A new project is created automatically each time the application is run. On the lower left panel, enter the Project Information.
The import of projects from the previous version is also provided.
The installation file comes with several test projects from which you can start working in MLinkPlanner.
Sites
Before creating microwave point-to-point links, point-to-multipoint base stations or subscriber stations links, you must first create sites. Sites are locations that can be connected via point-to-point or point-to-multipoint links. A site has only three characteristics - name, latitude, longitude.
Creating Sites
To work with sites, go to the Sites menu item in the left menu.

Figure 2. Sites menu









- Move this site up.
- Move this site down.
- Import sites from *.csv or *.kml files.
- Export sites to Microsoft Excel.
- Sort sites in alphabetical order.
- Add sites from the clipboard.
- Delete all sites.
- Position the map with the site at the center of the screen.
- Find and select a site in the table.
MLinkPlanner provides several ways to create sites:
1. Enter the name and coordinates of the site in the table.
2. Use the context menu when clicking on the base map.
3. Import sites from a CSV or KML file.
4. Copy from spreadsheets via the clipboard.
Table Entry
Enter the site name and its geographic coordinates in the relevant fields. The geographic coordinates are specified as point of compass, degrees, minutes, and decimal seconds (e.g., N35 36 23.8). The numbers should be separated by a space. After pressing ENTER, the coordinates will be automatically converted to the format specified in the Settings menu. Alternatively, you can enter coordinates as Point of Compass and Decimal degrees (N12.34567). After pressing ENTER, they will also be converted to the selected format. The site icon will be displayed on the base map. If you do not specify a hemisphere, then the northern hemisphere will be set by default.
Use the Context Menu
You can also create a site by right-clicking on a location on the base map. Being in the main menu item Sites, right-click on a location within the basemap and select Create a new site from the context menu; you can rename it later. The new site will be added to the map and appended to the bottom of the site table.
Please note that the context menu with the line "Create new site" appears on the base map only when you are in the Sites main menu.
Import Sites from a CSV or KML File
You can import sites into MLinkPlanner from any spreadsheet by exporting the sheet as a CSV file (separator – “;”). The required fields for each site are Name, Latitude, and Longitude. Geographic coordinates should be specified as Point of compass, degrees, minutes, and decimal seconds (N35 36 23.8). The numbers must be separated by a space. Point of Compass and Decimal degrees (N12.34567) is also an acceptable format.
To import from CSV: save the spreadsheet as a CSV file (separator – “;”) and then click Import sites from *.CSV, *.KML.
Figure 3. Example of CSV file with sites to be imported

Figure 3. Example of CSV file with sites to be imported
The program also allows you to import sites from KML files that can be prepared using the Google Earth application. To import sites, click the Import sites from *.CSV, *.KML button and select the * .KML file, while all point features from the KML file will be imported as sites.
Imported sites are added to existing ones.
Copy from Spreadsheets via Clipboard
Copy the cells with the names of the sites and their coordinates in the Excel or Word spreadsheet to the clipboard and then click Add sites from the clipboard on the toolbar, after which the corresponding sites will appear in the table.
Working with Sites
To delete one or several sites, select the corresponding rows in the table and press the Delete key. Deleting a site will not lead to the deletion of PtP microwave links already created on the basis of this site, as well as the base or subscriber station PtMP.
By double-clicking on the row with the site in the table, this site will be shown on the base map in the center of the screen.
You can move the site using the right mouse button - select the site in the Sites table, then right-click on the location on the base map, and select Move site in the context menu.
You can quickly find a site in a table using the Find and select a site in the table tool
Equipment Editor
MLinkPlanner 2.0 uses special format equipment files with the extension * .eqt. These files contain specifications of different types of Point-to-Point and Point-to-Multipoint equipment.
The software comes with a set of such files for a wide range of modern Point-to-Point and Point-to-Multipoint equipment. Therefore, in most cases, the user does not need to search for detailed specifications for the main radio equipment. It is enough to choose equipment from the supplied set. One such file may contain specifications for a whole family of products. The common parameters for this Family are modulation and coding parameters, as well as a set of bandwidths.
An example of such a family for Point-to-Multipoint equipment is the popular airMax family by Ubiquiti Networks, which includes many products of base stations and subscriber stations that are compatible with each other. Equipment for Point-to-Point example family is FibeAir IP-20N by Ceragon, which includes a set of external placement of different modules (RFU) on different frequency bands.
We are constantly updating the files with equipment parameters, the current set can be downloaded from our website https://www.wireless-planning.com/equipment. These specifications are taken from open sources and are supplied "as is;" we carefully check it, but we do not guarantee the reliability.
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.

The procedure for creating the specification file:
1. Fill in the Family field and the Family information field (if necessary; this is just an information field).
2. Go to the Family Parameters panel. 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.
3. 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.
4. Now you can enter information about each product:
4.1 Select your product from the drop-down list.
4.2 Fill in the Product Information Field (if necessary; this is just a text field).
4.3 If an external antenna is used with this model of equipment, select this. 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.
4.4 Insert a photo or graphic image of the product. You can download the image from a file or through the clipboard, using the tools above the image. 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.
4.5 From the bandwidth drop-down list, select the required product bandwidth. Fill in the columns Channel bitrate, Tx Power, and Rx threshold for each modulation type. For Point-to-Point equipment, it may be necessary to additionally fill in the adaptive equalizer parameters for each modulation type and if the equipment family supports Co-channel mode, then XPIF and Co/I parameters.
4.6 Repeat the steps in clause 4.5 for all bandwidths supported by the product
5. After filling in the information for each product, save the specification file (extension * .eqt).
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.
Toolbar:








- Copy all parameters of the product modulation table to the clipboard (used to create new products based on existing ones).
- Paste modulation table parameters from the clipboard (used to create new products based on existing ones).
- Automatically fill receiver threshold sensitivity values for all bandwidths based on the values of the first bandwidth. 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.
- Rename products (replace the combination of any letters / numbers / symbols in the product name).
- Apply selected parameters in the table for all products with this bandwidth.
- Apply selected parameters in the table for all bandwidths for this product.
- Display the product specifications for the selected bandwidth in the form of a datasheet, which can be saved in PDF, Word, or Excel formats.
- Load product data from Pathloss RAF file PL50_ASCII_RADIO_SPEC_03/04 with ADMOD
