Propagation Models for Radio and TV Broadcasting Projects

When working with television and radio broadcasting projects, one of the following propagation models is usually used:

-    ITU-R P.1812-4
-    ITU-R P.1546-6
-    Longley-Rice (ITM) v 1.2.2 

 

For more information about these models, see the Propagation Models for mobile section.

Simulcast Delay Spread

This prediction is used for single-frequency network (SFN). Inter symbol 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:

To reduce interference between simulcast transmitters, it can be useful to artificially delay the signal transmitted from a given location using Simultaneous Delay Offset entered in Transmitter Parameters. By carefully assigning offsets to different transmitters, some control can be exercised over where interference occurs.

FCC Countours

RadioPlanner 3.0 allows you to calculate service and interference contours using FCC propagation curves. These contours are used in North America in accordance with FCC rules, and are also recommended for use when planning television and FM broadcast stations in some countries.

Add Map Layer

Adding a contour with selected parameters to the map as a layer

To calculate an FCC contour, go to the parameters menu of the transmitter for which you want to calculate the contour. Enter the required value for the electromagnetic field strength (Minimum field strength) and select the type of FCC propagation curve:

   - F (50,50) - Service contour curve for FM broadcasting and analog television

   - F (50,10) - Interference contour curve

   - F (50,90) - Service contour curve for digital television

 

After clicking the “Add map layer” button, the FCC contour will appear on the base map as a vector layer. The name of this layer displays information about the transmitter’s name, the type of curve, and the field strength level. By default, service contours are displayed in black and interference contours in red. You can change the display settings of this layer as desired; working with it is no different from working with other vector layers on the map.

ITU-R P.1546-6 Contours

To calculate an ITU-R P.1546-6 contour, go to the parameters menu of the transmitter for which you want to calculate the contour. Set the value of the electromagnetic field strength (Minimum field strength), select the type of path, and enter the percentage of locations and times for which you want to perform the calculation.


The following contours are commonly used (percentage of locations, percentage of time):


-    (50.50) - Service contour for FM broadcasting and television
-    (50.10) and (50.1) - Interference contours

 

After clicking the “Add map layer” button, the ITU-R P.1546-6 contour will appear on the base map as a vector layer. The name of this layer displays information about the transmitter’s name, the type of curve, and the field strength level. By default, all contours are displayed in black. You can change the display settings of this layer as desired; working with it is no different from working with other vector layers on the map.

Point Analysis in Terrestrial Broadcasting

In this panel, you can see results of field strength calculations at any point on the map.

You can change the current point on the map by clicking on a new location with your mouse. The path profile is a vertical section of terrain between transmitter and receiver that shows information about elevations and clutter. The colors that mark various obstacles on the profile correspond to those used in the clutter model.


The path profile shows antenna radiation center heights for both transmitter and receiver as well as Fresnel zone for radio beam, free space loss, diffraction loss due to terrain and clutter surrounding the receiver.


Find the required transmitter and click on it with your mouse (not to be confused with activity tag). Information about selected sector will appear above path profile.


Below path profile is a table displaying results of field strength calculations.

Calculation of the Population Covered by Television and Radio Broadcasting

RadioPlanner allows you to determine the population in the coverage area. Based on the calculation results, a list of localities covered by broadcasting is formed, indicating the population in each locality and the total population in the coverage area.


To calculate population covered, you first need to calculate the downlink field strength coverage for the transmitter (or several transmitters). The population covered will be made for the lowest field strength level used in the calculation.


The population and list of localities covered by the broadcast can be obtained from the OpenStreetMap project data or a local dataset (CSV file). In both cases, the population covered is counted according to the following algorithm. In the center of each settlement, there is a point, the entry of which into the coverage area with a given field strength is the basis for including the entire population of this settlement into the coverage area. If the OpenStreetMap database is used for the calculation (in this case, a copy of the database located on our server is accessed), then these points are point objects - settlements with the tag place = city; town; village; hamlet, and the corresponding population tag.


To calculate the population covered, go to the "Report" menu and select the calculation method - using OpenStreetMap database or a custom CSV file. If you have selected the OpenStreetMap database, then click on the "Open Report" tool and a spreadsheet will appear with the population and the list of settlements covered by the broadcast. This spreadsheet will also show the total area of coverage in square kilometers, as well as the average coverage radius (only when calculating coverage from a single transmitter).

Measurement file in CSV format

 

Operating procedure:

 

1. Based on the results of field measurements, prepare a file with the measurements results.


2. Specify the antenna gain, cable loss and impedance for the measuring receiver path. The height of the receiving antenna is set in the network parameters.


3. Upload measurement files to the transmitter. The results of the measured and calculated receiving levels along the route will appear. Measurement levels are indicated in black, calculated levels - in a color that corresponds to the clutter type at a given point (yellow - open space). The abscissa shows the route point numbers. Hovering over the plot displays the calculated and measured levels, the difference in levels, the distance to the site in kilometers, and the clutter type. If necessary, perform the preliminary processing. When you click on the plot, a context menu appears, in which you can delete a point with the measurement result.

The table below the plot will indicate the number of points, the average error, the standard deviation of the error, as well as the recommended loss values for different clutter types, at which the average error will be zero. When you click on the button "Apply Tuned Clutter Losses to Propagation Model", the values for the points of the plot will be recalculated taking into account the tuned values, as well as the loss values in the "Propagation Model" menu will be changed. To assess how the new obstacle loss values will affect the coverage calculation result, you need to re-calculate the coverage.


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

Air-to-Ground Communication Coverage Prediction

RadioPlanner 3.0 can predict coverage for air-to-ground radio systems operating in the VHF, UHF, and microwave frequency bands. 
The system type must be set to Air-to-Ground Communication.

 

The set of parameters for the Site and Mobile Unit is similar to that of the mobile communication network.

Maximum study radius, km The larger the radius, the longer the computation time. Do not set an unnecessarily large calculation radius.

Propagation Model for Air-to-Ground Radio
 

The propagation model is a hybrid model based on the recommendation ITU-R P.528-3 (02/2012), “Propagation curves for aeronautical mobile and radio navigation services using the VHF, UHF, and SHF bands” and the recommendation ITU-R P. 526-14 “Propagation by Diffraction.”


The applicable hybrid model takes into account the following factors affecting the propagation of radio waves along the air-to-ground path:
-    Free space loss
-    Diffraction loss along the path taking into account the curvature of the Earth and the terrain profile extracted from the DTM
-    Variation of the received radio signal due to multipath fading

Time Availability, %

By choosing a particular time percentage, the calculated received power values are the power levels that will be exceeded at least that percentage of time.

Margin, dB

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 that your signal level estimate is indeed above the specified signal level.

Area Study Types for Air-to-Ground Radio
 

For the Air-to-Ground Communication project, you can choose one of the following area study types:


-    Received power Air-to-Ground link 
-    Received power Ground-to-Air link 
-    Best Server Air-to-Ground link 

 

The area study resolution for air-to-ground calculations corresponds to one screen pixel for magnification = 7 (Low), magnification = 8 (Medium), and magnification = 9 (High). For a geographic latitude of 55 degrees, this is approximately 720, 360 and 180 meters, respectively. The higher the resolution, the longer it takes to calculate.

Received Power Air-to-Ground/Ground-to-Air Link

In these types of calculations, the map displays different colors of coverage areas for different heights of the Mobile Unit (aircraft). You can set from one to eight different altitude levels.

Some Features of Coverage Calculating for Air-to-Ground Radio

For a certain combination of data (heights of the site and mobile unit, frequency, power, service threshold, and time availability), a band may appear on the radio coverage area indicating lack of communication (in the example below, such a band is present at a distance of 107-134 km in the radial direction from the base station).

Radioplanner a1.png

This means that in this zone, the mobile unit (aircraft) will be in the area of strong influence of multipath due to reflection from the Earth’s surface and time availability will decrease. Model ITU-R P.528-3 (02/2012), which is based on the IF-77 Electromagnetic Wave Propagation Model by M.E. Johnson and G.D. Gierhart, specially designed for aeronautical radio communications, takes this effect into account. A plot of received power versus distance for the example in question is shown below. It shows that at a time availability of 95% for the level of -88 dBm (-118 dBW), the curve has a bend, which determines the dip in received power and the corresponding band in the coverage area.

RadioPlanner a2.png

In fact, the appearance of such a band in the coverage area does not mean a significant reduction (within 5-7 percent) in time availability in this area. In practice, such a decrease in time availability in a small area within the coverage area can be considered acceptable.


In order to take this assumption into account, a calculation should be made for the average power of the received signal (time availability 50%), taking into account an additional margin for fading within 5-7 dB.

After which, the calculation result for the example considered above will look like this:
