Mobile networks

Frequency planning for a mobile network is a complex iterative process that is influenced by many factors. In practice, it is carried out by drawing up a frequency plan for the initial approximation network taking into account the requirements for coverage, number, and distribution of subscribers, communication quality, available frequency bands, features of the standard used, and other conditions. Then, the radio coverage of the network is calculated taking into account the co-channel, and adjacent channels’ interference for the selected frequency plan and the optimization of the parameters of the base stations. The frequency plan is performed in order to reduce the influence of the interference on the network coverage.

The purpose of this user manual is not to educate users on the principles and features of frequency planning of mobile networks. A sufficient number of books have been published on this topic.

A general blog diagram of the mobile network planning algorithm is shown in Figure 12.

Mobile Units

The mobile units’ characteristics in the Mobile Units menu. 

Figure 13. Mobile Units

Type                                              Name (model) of Mobile Unit, text field
Tx Power                                      Transmitter power, W
Rx Threshold                                Receiver threshold sensitivity, dBm
                                                       This parameter is taken into account when performing the calculation of the radio coverage “Areas                                                           with signal levels above both the base and mobile thresholds,” as well as Point Calculations.

Antenna Height                           Antenna height relative to ground level, m
Antenna Gain                              Antenna gain, dBi

The application allows calculating radio coverage for two types of mobile units, since, for example, in professional wireless networks portables and mobiles subscriber stations are often used, which differ in both energy characteristics and antenna height relative to ground level.

Base Stations

The characteristics of the radio equipment of the base stations in the Base Station Network menu. After creating a new project, the list of base stations is empty.

               - Create a new base station

               - Import sites from *.csv file

               - Sort base stations in alphabetical order

               - Delete all active base stations


               - Import base station parameters from Microsoft Excel document

               - Export active base station settings to Microsoft Excel

Creating a Base Station

To create a new base station, click on Base Station Network in the Tree View interface, then click the         button in the panel that opens, then select the template from which the new base station will be created.

Figure 15. Template selection for a new BS

Import sites from *.CSV file

You can also import sites from CSV files (text format, where the separator is a semicolon).
This is a universal format in which you can save a spreadsheet from any spreadsheet editor (Excel, LibreOffice Calc, and others), as well as databases.

The required fields for each point object are BS name, Latitude, and Longitude. Format coordinates - HEMISPHERE degrees minutes seconds (N35 23.8 36) or HEMISPHERE decimal degrees (N12.34567). 

To import sites, click on the button         (import sites from * .CSV) and select a CSV file, then select a template from which new base stations will be created with coordinates of imported sites.

Figure 16. Example of a CSV file with the imported sites

Import/Export BS Parameters to Excel Spreadsheet

The program can export the parameters of the base stations to the Microsoft Excel spreadsheet, as well as import data from this spreadsheet. This function can accelerate the loading of source data for a network with a large number of base stations, as well as simplify the exchange of source data between the user and the customer. The format of the table can be found by exporting the parameters of base stations for one of the test examples.

Figure 17. Example of spreadsheet

When importing/exporting a spreadsheet, the following should be considered:

1. Export to a spreadsheet is performed only for active base stations

2. When importing from a spreadsheet, the imported base stations will be added to the existing BS of the current project. That is, if you need to completely replace the information on base stations, then before performing the import, you should remove the existing base stations from the project.

3. Since the antenna patterns in the table are not saved, when importing, all radiation patterns are replaced with OMNI; the antenna name is taken from the spreadsheet. The radiation patterns can then be easily replaced with group parameter changes.

4. If in the base station sector, the antenna-feeder transmission and reception path are the same, then when preparing the table, you can fill in the antenna-feeder path parameters for the transmit path only, and do not fill in the receive path parameters - just leave the corresponding cells of the spreadsheet empty.

When clicking in the Tree View interface panel on the created base station, the Base Station Details panel will open, where you can edit the name, coordinates, specify additional text information about the base station, and find out the elevation of the base station relative to sea level.

Figure 18. Base station parameters

Using the tools on the Base Station Details panel, you can do the following:

 - Create a new base station as a copy of this base station

- Move this base station up or down

- Delete base station

- Load the base station parameters from the template

- Save the parameters of the base station (including the parameters of all its sectors) as a template

- Position the map with the base station at the center of the screen

Name                          Base station name, text field.

Other Information     Text box for any additional base station information

When creating a base station, at least one sector of this base station is automatically created. 

There is an activity icon in the Tree View interface panel next to each base station and sector. For the sector to be calculated, this sector must be marked as active (a dot in the center of the icon).

Clicking on the base station sector will open a panel with the parameters of this sector.

An antenna pattern file is a standard MSI file that can be downloaded from the antenna manufacturer’s website. Antenna patterns are integrated into the project file.

Group change of active sector parameters based on the parameters of the current sector is a useful feature that allows you to instantly change the parameters of any sectors in accordance with the parameters of the current sector. 

The procedure for performing group parameter changes:

1. Mark sectors as active whose parameters need to be changed
2. Set the required parameter values in the current sector
3. Click the button          , select in the list the parameters that need to be changed in the previously marked active sectors, and click the OK button.

Context menu on the base map

When you right-click on the base map, the context menu appears in which you can:

1. Create a new base station at this point
2. Change the location of the current (selected) base station
3. Open the parameters of the nearest base station (focus on ...)

Propagation models

RadioPlanner 2.1 uses the following propagation models:

-    ITU-R P.1812-4 model (for mobile and broadcasting)
-    Longley-Rice (ITM) model v 1.2.2 (for broadcasting only; for mobile coming soon)
-    ITU-R P.1546-6 model  (for broadcasting only)
-    Combined ITU-R P.528-3 + P.526-14 model (for aeronautical radio only)

ITU-R P.1812-4 model


This model is described in detail in the recommendation ITU-R P.1812-4 (07/2015) A path-specific propagation prediction method for point-to-area terrestrial services in the VHF and UHF bands.

The following main factors which affect propagation are taken into account:


  • Diffraction loss on the path profile obtained from the SRTM data

  • The impact of local surrounding obstacles that exist in the landcover model

  • Temporal and spatial instability of the received radio signal (slow and fast fading)

Figure 21. Propagation model

You may select three parameters that determine the time, location, and prediction confidence margin of the calculation results:


Percentage of time (usually 90-95%). By choosing a particular time percentage, the calculated received power values are the power levels that will be exceeded at least that percentage of the time.

Percentage of location (usually 90-95%).  The location percentage indicates that a given power level will be exceeded in at least that percentage of locations for similar propagation paths. The percentage of location can vary from 1% to 99%. The model is not valid for a percentage of locations less than 1% or more than 99%.

Margin Prediction confidence margin. Since the received power level calculations are estimates, the prediction margin lets you specify a safety margin in dB so that you can be more confident your signal level estimate is indeed above the specified signal level.


Specify the location of the Mobile units:

- Mobile units with antennas below clutter height in urban or suburban environments 
- Mobile units with rooftop antennas near the clutter height 
- Mobile units in rural areas


Clutter loss

RadioPlanner calculates the signal power loss on local obstacles surrounding the Mobile unit using the landcover model with the different types of clutter (dense urban, urban, suburban, open land, water, and trees/forest). The landcover model was created based on OpenStreetMap ( and Global Forest Change ( projects.

Losses are calculated following Recommendation ITU-R P.1812-4; they depend on the following parameters:

- Antenna height of the Mobile unit
- Width of the streets
- Average (typical) height of clutter
- Type of clutter


The frequency range is set in the Base station Network menu, the antenna height for each of the two types of Mobile units (usually portable and mobile) in the Mobile Units menu, the typical width of streets is 27m (in accordance with ITU-R P.1812-4), and the landcover model determines the type of obstacles at each point.


To determine the loss according to ITU-R P.1812-4, the user should select Calculate the loss in rec. ITU-R P.1812-4 and specify in the table the average height of the obstacles of each type based on local conditions. Default data in Rec. ITU-R P.1812-4:

Clutter type                Clutter height (m)

Water/sea                                 0
Open/rural                               10
Tree/forest                              15
Suburban                                 10
Urban                                       15
Dense urban                            20

The user can also set clutter loss manually for each type of obstacle based on their own data - to do this, simply enter the losses into the table.

Clutter data

Use default clutter data or Use custom clutter data - The choice of the clutter data that will be used for calculations - the default clutter or the custom clutter. Custom clutter is created in the Clutter Editor (see the section Clutter Editor).

Area Study Details

In this panel, the user selects the type of calculation and sets its parameters.

For projects of the “Mobile Radio” type, you can select the following types of calculations: 

-    Received power Downlink
-    Received power Uplink
-    Areas with signal levels above both the base and mobile thresholds
-    Strongest (most likely) Server Downlink
-    C/I Downlink ratio using channel plan
-    Number of servers above Uplink

Received power Downlink/Uplink


Received power maps show those areas where a given signal power level is present at the receiver.

Figure 23. Received Power Uplink for P25 800 MHz network

For Mobile Unit No. 1 (portable), you can set from one to eight different levels of the received signal and thus simulate different reception conditions (for example, on the street, inside the car, indoors, etc.) or different data transfer rates.

For Mobile Unit No. 2, which is supposed to be a mobile subscriber station with an antenna on the roof of the car, only one signal level can be set.

In the calculations, you can also take into account interference on the co-channel and adjacent channels. For this, there are corresponding check-boxes in the bottom of the panel. In this case, the zones where the interference on the co-channel and/or adjacent channels exceeds the amount allowable, one will be excluded from the coverage area. A useful signal is a signal with the maximum level at a given point.

To take into account interference, it is necessary to specify the maximum permissible levels of interference on the co-channel (C/I) and adjacent (C/A) channels.

To calculate interference on adjacent channels, you must specify the channel bandwidth and the exact channel frequencies (these parameters are entered into the Channel Plan menu).

To calculate co-channel interference, it is sufficient to specify the frequency group in the sector parameters.

The calculation of interference is performed only for one type of subscriber station – Mobile Unit No. 1.



Areas with Signal Levels Above Both the Base and Mobile Thresholds


This area study type displays a map showing those grid locations where both the signal received by the mobile unit is above the remote receiver threshold and from where the signal received by the base station from the mobile is above the base threshold.
The calculations use the parameters of antennas, losses, transmitter power, and receiver sensitivity for the base and subscriber stations specified in the relevant menus.

This type of calculation can be performed for different conditions of use of Mobile Unit No. 1 (portable). For example, indoors, outdoors, and inside the car. Each condition of use has its own color and its own value of loss (margin) for signal penetration, which is indicated in this form.

For Mobile Unit No. 2, only outdoor calculations are performed.

C/I Downlink ratio using a channel plan


The carrier-to-interference ratio, C/I, is one of the essential quantities used in assessing system performance and affecting frequency planning. 

RadioPlanner allows you to calculate and display areas with different C/I values for interference on co-channel and adjacent channels at the input of a mobile unit receiver.

Carrier-to-interference ratio is calculated by first finding the strongest received signal power from any BS sector at each location. Then it calculates the sum of the received signal powers from all other co-channel sectors and adjacent sectors (taking into account adjacent channel attenuation), which also have relevant signal levels at a location. After the sum of the interference is found, the carrier-to-interference ratio is calculated.

The calculation of adjacent channel interference can be turned off, in which case only co-channel interference will be taken into account.

Description                                            Text field to describe Carrier-to-Interference ratio

To calculate co-channel interference, in the BS sector parameters, set the frequency group of the sector and set the C/I value. To calculate interference on adjacent channels, it is necessary to fill in the table of frequency groups with exact frequencies and set the channel bandwidth and C/A value (see section Channel Plan).

Number of Servers Above Uplink

When performing this study, the base map displays the areas of possible location of subscriber stations with the number of BS sectors with a received power level above the threshold.

This study type is often required when planning networks based on wireless technologies IoT LPWAN – LoRa, and others.

Point Calculations

In this panel, the user can see detailed results of the calculation of the received signal power in the “down” and “up” directions at any point, as well as the levels of interference on the co-channel and adjacent channels.

You can change the current point on the map by clicking the mouse on the place you want. The path profile is a vertical section of the terrain between the base station and the mobile unit with information about land elevations, forests, and buildings. The colors that mark the various obstacles on the profile correspond to the colors of the landcover model.

The path profile shows the height of the antenna radiation center of the selected BS sector and the subscriber station, as well as the Fresnel zone for the radio beam, the loss in free space, the diffraction loss due to the terrain, and the obstacles surrounding the mobile unit.

The BS sector is selected on the left side of the panel in the general network Mobile Network. Find the BS sector you need and click on it with the mouse (don’t be confused with the activity tag), after which information on this sector will appear above the path profile.

Figure 31. Point calculations

You can also select a mobile unit (No. 1 or No. 2), the parameters of which will be taken into account in the calculations.

Under the path profile, a table appears with the results of calculating the power levels “down” and “up” for the selected sector (it is highlighted in the table in color) and for sectors of other BS. Only sectors that are marked as active are accepted for calculation. In addition, in order for a sector to appear in the table, it is necessary for it to fulfill one of the following conditions: the threshold sensitivity level of the receiver of the selected type of mobile unit must be bigger than the “down” level or the threshold sensitivity level of the BS sector receiver must be higher than the “up” level. Rows in the table can be sorted by frequency groups and received power levels “down” or “up.” Also, using the drop-down list located below the table, you can display the results for only one frequency group.

The selected BS sector is considered to be a sector with a useful signal; signals from sectors with the same frequency group are considered to be co-channel interference and signals from sectors where there are frequencies adjacent to a selected sector are adjacent channel interference. Based on this, below are the calculated values of interference levels along the co-channel and adjacent channels for the “down” and “up” directions.

Import Measurement Results and Propagation Model Tuning

The user can import the results of measurements of the received signal power levels and compare with the calculated values and then adjust the parameters of the propagation model.

Operating procedure:

1. Prepare separate files of received power levels for each of the necessary sectors of base stations.
The measurement file is a CSV format file, each of the lines of which contains three parameters: the level of the measured signal from one BS sector in dBm; geographical latitude; geographic longitude. The separator of parameter values is a semicolon.

Formats for the representation of geographic coordinates are Hemisphere Degrees SECOND MINUTES (N35 36 23.8) or HEM DECIMAL DEGREES (N12.34567).

Figure 32. Sample measurement file

2. Upload measurement files to the appropriate BS sectors in “Mobile Network” - “Sector Settings.”

Here, using the             button, you can view the downloaded measurement data for the BS sector and, if necessary, perform the preliminary processing:

Add New Layer with Measurement Points

Minimum Gap

Add a custom measurement layer to the map with averaging within the specified minimum distance. The data in the table does not change. The resulting layer will appear among the user layers; the layer name will correspond to the BS name and sector direction.


3. In the “Measurement Analysis” menu, the results of the comparison of the measured and calculated levels for each of the sectors for different clutter types will appear - the average error and the standard deviation of the error. Also, the recommended loss values ​​for different clutter types, for which the average error will be zero, will also be indicated. On the graph, you can see the distribution of measured and calculated signal level values ​​for different clutter types.

Figure 34. Measurement Analysis

4. Now, based on the analysis of the results obtained for different clutter types, a decision is made regarding the need to tune the values of the previously used clutter losses in the propagation model.

Calculator of the Noise-Adjusted Faded Performance Threshold 

The influence of man-made noise cannot be ignored in the frequency bands where most of the professional mobile radio communication systems operate (136-174 MHz and 403-470 MHz).

The calculator built into the software determines the Noise-Adjusted Faded Performance Threshold for various environmental conditions and frequencies.

The calculations take into account Delivered Audio Quality (DAQ) according to the methodology described in the TIA TSB-88.1 recommendation. The typical parameters of the receiver-demodulator of all land mobile radio systems are built into the calculator - data is taken from Table A1 “Projected VCPC Parameters for Different DAQs" TIA TSB-88.1-D.

Next, a Noise-Adjusted Faded Performance Threshold is calculated, taking into account one of the three research reports for different categories of land cover:

Figure 35. Noise-Adjusted Faded Performance Threshold  Calculator

To calculate the Noise-Adjusted Faded Performance Threshold, the user must specify:

1. Reference receiver sensitivity in dBm or µV - This is usually given in the technical specification as receiver sensitivity with 12 dB SINAD for analog systems or with BER = 5% for digital systems.
2. Type of land mobile radio system
3. DAQ required, usually DAQ = 3.0 or 3.4
4. Select the research report on which the calculation will be based and the category of land cover.
5. Specify the carrier frequency.

After changing any field of source data, the calculation is performed automatically. If an empty field appears as a result of the calculation, this means that incorrect data has been entered on receiving equipment (not physically feasible) or man-made noise graphs are beyond the frequencies at which the studies were performed.

Clutter Editor

RadioPlanner allows you to create custom clutters using the built-in Clutter Editor. The custom clutter model is formed by replacing the user-corrected areas in the default clutter model. A base map with actual satellite images is used as a data source for the custom clutter.

To start Clutter Editor, click the button          on the main program panel.

Menu commands are designed as a toolbar. When you hover over each of the icons, a hint appears.

The current map zoom can be changed by scrolling the mouse wheel. The display of the default and custom clutter on the map

starts with a Zoom of at least 11. Navigation on the map is performed using the left mouse button while pressing                button. In polygon drawing mode, the map can be moved by clicking on the mouse wheel.

The procedure for preparing a custom clutter consists of two stages:

1. Drawing polygons for various clutter categories on the basemap

In order to draw a clutter polygon of the desired category, click on the corresponding toolbar icon; the mouse pointer will change at the crosshairs. Click all vertices of the polygon with the mouse; to finish drawing the polygon, click on the right mouse button. Then you can proceed to draw the next polygon of the selected category. To change the clutter category - click on the desired icon on the toolbar. Using the toolbar, you can delete individual polygons or all polygons at once, as well as cancel or return up to ten actions in the editor.

When drawing polygons, their hierarchy should be taken into account, which is enhanced by looking at the category icons in the toolbar from left to right. For example, inside the Open/Rural polygon, you can draw any of the polygons and inside the Trees/Forest polygon, you can draw Urban polygons, etc. It is convenient to start the adjustment of the default clutter by drawing Open/Rural polygons, inside which others polygons are then drawn.

Polygons can be saved in a file with *.plg extension.

2. Conversion of polygons to the Custom Clutter

To convert drawn polygons into a Custom Clutter, click                button on the toolbar, after which the program converts polygons into a Custom Clutter matrix. Elements of the Custom Clutter matrix are stored in the cache along with the Default Clutter matrix.
You can choose a clutter model the Default or Custom one, which will be taken into account in the calculations and displayed as a layer on the map is carried out in the “Propagation model” menu in RadioPlanner.

You can choose a clutter model, Default or Custom, which will be taken into account in the calculations and displayed as a layer on the map, which is carried out in the “Propagation model” menu in RadioPlanner.

Using the corresponding buttons of the Clutter Editor toolbar, you can turn on/off the showing of the base map, drawn polygons, as well as the Default and Custom clutters.

When adjusting the clutter model, it should be noted that the ITU-R P.1812-4 propagation model used in the program assumes that the clutter model is detailed with a resolution of tens of meters. Accordingly, it makes no sense to outline individual buildings and trees; it is enough to draw building blocks and forests.
