Hi
I understand that you want to know the frequency ranges available in MATLAB and how to setup a pseudorandom range for transmission.
There are no inherent limitations to specific frequencies, but it depends on the simulation scenario that you design.
To setup a pseudorandom range for transmission, you can have a look at the example in the following documentation link for the 'transmitter’ function. This example creates a satellite link between two ground stations
To transmit a pseudorandom frequency every second, you must set the ‘AutoSimulate’ property value of the 'satelliteScenario’ object to ‘false’. You will then be able to modify the frequency for the transmitter object. Here is an example to generate a pseudorandom frequency:
ka_band_min = 26.5e9; % Convert to Hz
ka_band_max = 40e9; % Convert to Hz
% Output a random frequency within the Ka band in Hz
random_ka_frequency = ka_band_min + (ka_band_max - ka_band_min) * rand();
You can use the ‘random_ka_frequency’ variable’s value as the transmitter frequency and use the ‘advance’ function to move the simulation forward.
Kindly refer to the following documentation for all the functions that are mentioned above.

Hope this helps!
