how can I create and display a transmitter txsite with 'CoordinateSystem' set to 'cartesian'?

I am new to matlab and I could not find any examples. Please help

Hi Varsha,

Can you share the script that you are working on so that we can understand the issue by reproducing it from our end?

Hi Pratyush,

I was trying to create a wireless rf transmitter at a particular coordinate location using the code below

txs=txsite('CoordinateSystem','cartesian', ...

'AntennaPosition',[4;4;12], ...

'AntennaHeight',antHeight, ...

'TransmitterFrequency',f, ...

'TransmitterPower',txPower);

coverage(txs);

It shows the error as mentioned before...

Thanks,

varsha

Hi Varsha,

The RF Propagation interface does not offer visualization support for showing Cartesian sites, their coverage, or their antenna patterns.I have brought this issue to the concerned people and it might be considered in any future release.

As a workaround, one can use MATLAB Graphics to create a custom plot. The following example is available as of R2021a and shows how to plot Cartesian sites and rays using MATLAB Graphics:

Hope this helps!
