ITU-R P.1812-6 Propagation Model
The ITU-R P.1812-6 Propagation Model is described in detail in Recommendation ITU-R P.1812-6 (09/2021) “A path-specific propagation prediction method for point-to-area terrestrial services in the frequency range 30 MHz to 6 000 MHz.”
This model takes into account factors such as diffraction loss on path profile obtained from DTM data; impact of local surrounding obstacles determined by clutter model; and local and time variability of received radio signal.
ITU-R P.1812-6 Propagation Model
Location, %
Location percentage (50%-99%, typically 50%, 90% or 95%) indicates that a given power level will be exceeded in at least that percentage of locations for similar propagation paths. Set 50% if you want to completely exclude the influence of Location variability.
Time , %
By choosing a time percentage (50%-99%, typically 50%, 90% or 95%), the calculated received power values are the power levels that will be exceeded at least that percentage of time. Set 50% if you want to completely exclude the influence of Time variability.
Confidence margin, dB
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.
σLN, dB
Lognormal large-scale (shadow) fading standard deviation, dB. This value depends on the digital terrain model (DTM) resolution and carrier frequency. Typical value 2-5 dB for modern DTMs.
σR, dB
Small-scale fading (Rayleigh) standard deviation, dB. Typically 7.5 dB
σt, dB
Time variability standard deviation, dB. At distances up to 50 km, the σt usually varies for between 2-3 dB (Land), and up to 9 dB for the Sea. See Table 3 in Recommendation ITU-R P.1406-2 "Propagation effects relating to terrestrial land mobile and broadcasting services in the VHF and UHF bands"
Fade margin, dB
Fade margin, dB. Calculated total fade margin depending on location and time variability, as well as the confidence margin.
Clutter loss
Clutter loss is calculated according to Recommendation ITU-R P.1812-6 and depends on factors such as antenna height of the mobile unit, frequency, typical width of streets, average height of clutter, and clutter type.
The frequency and antenna height for each of the two types of mobile units (portable and mobile) are set in the Network menu. The typical width of streets is 27m (in accordance with ITU-R P.1812-6). The clutter model determines the type of obstacles at each point.

You can also manually set clutter loss for each clutter type based on your own data by entering the losses into the table.
ITU-R P.1546-6 Model
The model is based on recommendation ITU-R P.1546-6 (08/2019): "Method for point-to-area predictions for terrestrial services in the frequency range 30 MHz to 4000 MHz"
Model ITU-R P.1546-6 is empirical because it is based on experimentally obtained field strength curves versus distance for different frequencies, antenna heights, path types, and time probability. In Recommendation ITU-R P.1546-6, in addition to these curves, losses are also determined by the terrain clearance angle correction from the receiver side and the correction for the height of the clutter surrounding the receiver.
ITU-R P.1546-6 Propagation Model
The approach to fade margin calculation, taking into account location and time variability as well as large/small-scale and time fading standard deviations, is the same as described in the ITU-R P.1812 Propagation Model

Longley-Rice (ITM) Propagation Model v 1.2.2
The Longley-Rice propagation model, also known as the Irregular Terrain Model (ITM), is considered the industry standard for coverage prediction in North America. RadioPlanner 3.0 uses version 1.2.2 of the Irregular Terrain Model in PTP-mode.
Longley-Rice Propagation Model Parameters
Time, %
By choosing a time percentage (50%-99%, typically 50%, 90% or 95%), the calculated received power values are the power levels that will be exceeded at least that percentage of time. Set 50% if you want to completely exclude the influence of Time variability.
Situation, %
Situation (location) percentage, (50%-99%, typically 50%, 90% or 95%) indicates that a given power level will be exceeded in at least that percentage of locations for similar propagation paths. Set 50% if you want to completely exclude the influence of Situation variability.
Margin
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.

Okumura-Hata Propagation Model
This empirical model was developed by Hata and is based on Okumura’s experimental data taken in the Tokyo urban and suburban area. When calculating coverage using this model, you must determine which category the site location area belongs to: Urban Area, Suburban Area, or Open Area. Path loss is calculated using different formulas depending on the type of area.
- Urban Area: Built up city or large town including buildings and houses with two or more stories, or large villages and tall trees, green lands.
- Suburban Area: Small town, village or highway scattered with trees and houses, some obstacles near the mobile set but not very congested and scattered industrial plants.
- Open Area: No tall trees or buildings in the radiowaves path, open fields, land cleared for 300–400m ahead, very low congested area, no factories such as farm lands and rice fields.
Path loss is calculated using different formulas, depending on the type of area.

Requred service C/(I+N) ratio, dB This is the minimum acceptable C/(I+N) ratio required by the receiver for “acceptable” performance. “Acceptable” can mean a variety of things in terms of subjective signal quality, so this number can be adjusted to represent systems of varying quality or marginal quality. An area with a C/(I+N) below the Required Service C/(I+N) ratio will be shown on the map as an interference zone.
For Mobile Unit No. 1 (portable), you can set from one to eight different levels of received signal to simulate different reception conditions (e.g., on street, inside a car, indoors).
For Mobile Unit No. 2 (mobile radio with an antenna on the roof of a car), only one signal level can be set.
The interference calculation always takes into account the noise component, which depends on the noise bandwidth and receiver noise figure. These settings are entered in Noise and Interference in the Network system settings.

C/(I+N) Ratio Downlink/Uplink
The carrier-to-interference+noise ratio (C/(I+N)) is an essential quantity used in assessing system performance and affecting frequency planning. RadioPlanner allows you to calculate and display areas with different downlink/uplink C/(I+N) values for interference on co-channel and adjacent channels.
Carrier-to-interference+noise ratio is calculated by first finding the strongest received signal power at each location, then calculating the sum of received signal powers from all other co-channel and adjacent sectors (taking into account adjacent channel attenuation) that also have relevant signal levels at that location. After finding the sum of interference, the carrier-to-interference+noise ratio is calculated.
The interference calculation always takes into account the noise component, which depends on noise bandwidth and receiver noise figure entered in Noise and Interference in Network system settings. The calculation of adjacent channel interference can be disabled to only take into account co-channel interference.

This area study shows the availability of service based on a Gaussian (“normal”) distribution in dB. The calculation determines the “fade margin” at each study location based on the received signal strength with respect to a receiver threshold. The percent reliability is then a lognormal distribution of the fade margin in dB. Interference and noise are not taken into account in the calculation. The values of standard deviations in the calculation are taken from the “Coverage Probability” parameters, while standard deviation values in propagation model parameters are ignored.

Simulcast Delay Spread
This prediction is used for simulcast systems that transmit signals from multiple locations simultaneously on the same channel. Interference in the receiver will occur under certain conditions related to delay time between signals arriving at a given location and their relative power. The simulcast delay spread is calculated as follows:
The simulcast delay spread is calculated by considering only the six strongest signals at any grid analysis location. The results of the calculation are displayed in μs on the map.

Point Analysis
In this panel, you can see detailed results of received signal power downlink and uplink calculation at any point as well as interference levels on co-channel and adjacent channels. The path profile is a vertical section of terrain between site and mobile unit with elevations and clutter information. Clutter height in path profile is determined by height for each clutter type set in Geo Data menu.
Click on “Point Analysis” and then find the required sector in the interface tree and click on it (do not confuse it with the activity tag). A path profile from the sector to the current point on the map will appear. You can change the current point on the map by clicking on the desired location.
The path profile shows the height of the antenna radiation center of the selected sector and mobile unit, as well as the Fresnel zone for the radio beam, loss in free space, diffraction loss due to terrain, and loss on clutter surrounding mobile unit.
Point Analysis
You can select a mobile unit (No. 1 or No. 2) whose parameters will be taken into account in calculations.
Under the path profile, a table appears with results of calculating power levels of downlink and uplink channels for selected sector (highlighted in color in table) and other sectors. Only sectors marked as active are included in calculation. For a sector to appear in table, received signal level must be greater than corresponding downlink or uplink Rx Threshold (see Network menu). Values in table can be sorted in ascending or descending order by clicking on corresponding field in table header.
The selected sector is considered to have a useful signal; signals from sectors with same frequency are considered co-channel interference, and signals from sectors whose frequencies are adjacent to selected sector are considered interference from adjacent channels. With this in mind, the table shows the calculated values of the interference level, taking into account noise and interference in the co-channel and adjacent channel.
Fixed Wireless Access
RadioPlanner 3.0 allows you to plan Fixed Wireless Access (FWA) and Internet of Things (IoT) networks such as LoRa, SigFox, and others.
Users can perform calculations for multiple Customer Premises Equipment (CPEs) or IoT sensors, each with their own individual parameters (antenna height, antenna gain, antenna pattern, transmitter power, cable loss, and penetration loss). For ease of use and display on the screen, users can create separate CPE groups.
In the Fixed Wireless Access panel, users can:
1. Import CPEs/Sensors from a CSV file or manually create new CPEs/Sensors on the map.
2. Use multiple types of CPE/Sensor equipment.
3. Adjust the antenna height for an individual CPE/Sensor or multiple CPEs in the table.
4. Manually or automatically assign CPEs/Sensors to Base Station (BS) sectors based on various criteria.
5. View path profiles from the selected CPEs/Sensors to nearby base stations.
6. Generate a single network report or an aggregate throughput summary report for CPEs/Sensors in Excel.
To display the CPE and the link to the assigned BS on the base map, a separate layer has been created in ‘Map Layers’. Here, users can modify the CPE icon and line width. This layer can be saved in HTML, PNG, and KMZ coverage files.

The calculation of CPE - BS links is carried out according to the parameters specified in the “Propagation Model” menu. If the calculation takes into account clutter losses in accordance with Recommendations ITU-R P.1812/1546, these losses are determined for each end device taking into account the height of its antenna above ground level. The calculation can also take into account building penetration losses for each CPE/end device. The output report for each CPE or end device will display the received downlink/uplink power, C/(I+N) ratio, modulation type, maximum throughput, and other parameters.
General Procedure for Working in the Fixed Wireless Access Menu:
1. Load a list of CPEs from a CSV file or create a CPE manually using the right mouse button in the context menu. The CSV file format is described above. If you already have CPEs in your table, then when importing from a CSV file, new ones will appear at the end of the table.
2. Create one or more types of CPE equipment in the "Edit CPE Equipment" menu. Please note that for one type of CPE equipment, parameters for different networks can be specified.
3. Specify the type of equipment for each CPE in the table. To do this, point to the desired cell with the equipment and select the required equipment from the list that appears. You can select several cells in the table at once and set one type of equipment for them.
4. If your CSV file did not include data on antenna heights, or you created the CPE manually on the map, then indicate the antenna heights in the appropriate cells of the table. Here, it is also possible to select several cells at once and enter the same height for these cells.
5. If you want to assign BS sectors for all CPEs at once automatically, then select the criterion by which the assignment will be made - best server or best SINR - and click on the "Assign BS sectors for all CPE" button. After this, you will be asked to select a network for which the calculation and assignment of BS sectors will be carried out, and then automatic assignment will be performed. If there is only one network in the project, then automatic assignment will occur immediately. Please note that even if the CPE operates in different networks, it can be assigned and directed only to one BS site (the sectors are, of course, different). CPEs that do not have an assigned BS sector are displayed in the table in faded font.
6. If you want to view the path profile from the CPE to the BS sector or manually assign/reassign the BS sector, then first select the CPE you need in the main table, then select the desired network on the right and click on the "Assign BS Sector Manually" tool. In the window that opens with the path profile, you can select the sector you need, view the main calculation results, and assign/reassign the selected BS sector.
7. After the sector assignments have been completed for all CPEs, you can obtain the calculation results in Excel "Full report on the selected network in Excel" for one network or for several networks "Aggregate Bandwidth Summary Report in Excel (LTE/5G only)" . Only those networks that are marked in the main left menu “Networks” will be taken into account.
8. If the calculation results do not satisfy you, then change the parameters of the CPE (antenna height, equipment type, etc.) and perform the calculation again, and so on, until you get the desired result.

Coverage prediction for Fixed Wireless Access network
RadioPlanner 3.0 enables the display of coverage predictions for a Fixed Wireless Access (FWA) network or an IoT network (such as LoRaWAN) on a map. The algorithm used to calculate coverage for CPEs or IoT sensors differs from the one used for mobile units. Ths difference stems from the fact that while calculating mobile network coverage, the characteristics of one of two typical mobile units (UE1 or UE2) are considered. However, when calculating FWA coverage, the individual characteristics of each CPE or sensor are taken into account. These include antenna height, antenna gain, antenna pattern, transmitter power, losses in the cable, and building penetration losses. As a result, coverage prediction results are more accurate.
Upon calculation, a small circle will appear at the location of each CPE or sensor. The color of this circle will correspond to the result of the selected study type. The study type can be chosen from the menu of the corresponding network, and the calculation can be initiated there using a special tool ‘Calculate FWA Coverage’.
If a CPE/Sensor has an assigned BS sector, then the coverage calculation will be performed for this BS sector. If the CPE/Sensor does not have an assigned BS sector, then the coverage calculation will be performed for the sector with the best power at the receiver (Best Server).
When you hover your mouse over the CPE circle, the equipment parameters and calculation results will be displayed on the Legend.

Measurement Results Analysis and Propagation Model Tuning
RadioPlanner 3.0 allows you to tune clutter loss for a propagation model by comparing measurements with predicted Rx power values. Loading, preprocessing and analysis of measurement file for each sector is performed in Sector parameters panel.
Measurement Results Analysis Along a Route
Import of measurement data from a CSV file
Export of measurement data to a CSV file
Delete all measurement points
First prepare a file of received power levels for required site sector. The measurement file is a CSV format file with each line containing three parameters: level of measured signal from one sector in dBm; geographical latitude; geographic longitude. The separator of parameter values is semicolon. Formats for representation of geographic coordinates are Hemisphere Degrees SECOND MINUTES (N35 36 23.8) or HEM DECIMAL DEGREES (N12.34567).
Sample Measurement File
Upload measurement file to appropriate sector and perform preliminary processing if necessary:
On the results scatter-plot, measurement levels are indicated in black, while predicted values are indicated in a color corresponding to the clutter type at a given point (e.g., yellow for open space). The x-axis displays the waypoint numbers. When hovering the cursor over the graph, calculated and measured levels, level difference, distance to the site (in kilometers), and clutter type are displayed. When you click on the plot, a context menu appears, in which you can delete a point with the measurement result.
Below the plot is a table that displays the number of points, mean error, standard deviation of error, and recommended loss values for different clutter types that will result in an average error of zero. Clicking the “Apply Tuned Clutter Losses to Propagation Model” button changes the clutter loss values in the “Propagation Model” menu and recalculates the plot point values based on the tuned loss values. To assess the impact of the new clutter loss values on coverage calculation results, coverage must be recalculated.
A decision is made regarding the need to tune previously used clutter loss values in the propagation model based on an analysis of results obtained for different clutter types and sectors.

Coverage Prediction Comparison
RadioPlanner 3.0 allows you to compare results of current coverage prediction with previously performed predictions. This allows you to evaluate the impact on coverage by changing various site parameters, propagation model, etc.
To add a performed calculation to comparison, click on the Add Coverage to Compare button on top toolbar. When you go to Compare Coverage menu of main toolbar, this calculation result will be located on left side of screen while result of current coverage calculation will be displayed on right side. If Legend is enabled, it will display calculation parameters that mouse pointer is currently over.
Coverage Prediction Comparison
You can add multiple calculations to comparison and their names will appear in tree-view interface under Compare Coverage. When adding a calculation to comparison, RadioPlanner saves all calculation matrices so for large calculations it can take a long time and take up a lot of hard disk space. Manage maps in left and right panels (map shift and zoom) independently of each other. This allows you to compare two results of coverage calculation in detail. To rename a calculation in tree-view interface, double-click on it and rename it. To delete an unnecessary calculation, click on it and press Delete button on keyboard. When closing RadioPlanner, calculations added to comparison are not saved.
Reports
In the "Reports" menu, you can create different types of project reports - network configuration report, propagation model report, area survey type, and active sites configuration report.
You can also create a report on population coverage (currently only for broadcasting - see the corresponding section of this User Manual).
All types of reports open directly in Excel.

Noise-Adjusted Faded Performance Threshold Calculator
The influence of man-made noise cannot be ignored in the VHF and UHF frequency bands where most professional mobile radio communication systems operate.
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:
-
Recommendation ITU-R P.372-13 "Radio noise" (50-250 MHz)
-
OFCOM MMN measurement (AY4119) 2003 (50-1000 MHz)
-
Data from TIA TSB-88.2-D Part 2: Propagation and Noise (162 MHz)
Noise-Adjusted Faded Performance Threshold Calculation
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
3. DAQ required, usually DAQ = 3.0 or 3.4
4. Select the research report on which the calculation will be based and the environmental category
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.
