How to please do TX Coverage at 10 meters above the terrain? - AntennaToolbox

Hello everyone,

I would like to ask whether it is possible to model signal propagation using AntennaToolbox at certain height above ground, for example 10 meters. I am working on a project to determine minimum number of transmitters to cover certain area for drones, because they will fly at 10 meters above ground. I need to model the coverage at 10 meters above ground, which will result at less tranmistters being needed.

However, I have not been succesful yet. Is there please a was how to do it?

Thank you

Hi Michal,

From my interpretation you want to understand how signals propagate out from transmitters that are 10 meters high. This will help you figure out the least number of transmitters you need for drones flying at a certain height to capture a certain area of ground. You plan to map out the signal area from the height where drones fly to make sure the entire area is covered without using more transmitters than necessary and you want to use Antenna toolbox for that.

To model signal propagation at a height of 10m using MATLAB Antenna Toolbox you can follow the following steps,

1. Create a transmitter site with the ‘txsite’ function and set the 'AntennaHeight' to 10 meters.
2. Pick a propagation model that fits your setting (like urban or rural) by using the ‘propagationModel’ function.
3. If needed, add details about the environment, such as the landscape or buildings, that might change how the signal spreads.
4. Calculate and show the signal's reach at 10 meters using the ‘coverage’ or ‘coverageMap’ function.
5. Start with a certain number of transmitters and see if they are able to cover the terrain you require.
6. Keep tweaking your model and try to use fewer transmitters if you can. (You can also write a recursive MATLAB code for this step)

Please go through this documentation to understand the process in more detail,

It includes a range of detailed examples; please review them to comprehend the utilization of the Antenna toolbox for modelling signal transmission.

Additionally, examine the documentation of the function referenced in the procedure to gain a deeper understanding of its use and configure it to suit your specific problem statement.

Hello Krishna,

thank you very much for your comment. I should probably explain more what my problem is. I do not want to elevate the transmitter to 10 meters above ground. Coverage command gives you the map that show coverage at a ground level. I need to see the coverage at 10 meters above ground level. So some parts that are not covered at ground level might be perfectly covered at 10 meters above ground level where the drone will fly. I have read through the documentation of the toolbox and have not found a solution to this. Do you please know how to solve this problem?

Thank you

Michal
