txsite with 'CoordinateSystem' set to 'cartesian'.

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,

You may find this link helpful.

Thanks for the reply Pratyush. I have seen this link but it doesn't shows any example. I am not sure how to display the transmitter as show and pattern shows error while trying to display using the coordinate set to cartesian.

Thanks, Varsha

hi Pratysh,

My question is that I am using the txsite with cordinate system set to cartesian and antenna positions set. I would ike to know how could I display the trasmitter beam/pattern as I tried with 'show' and 'pattern' and it shows the error...... The 'show' function is not supported for sites with 'CoordinateSystem' set to 'cartesian'....

Could you please help me on this.

Thanks,

varsha

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!
