i was saying that jammers seem to be designed to transmit extra-noise in the DL band.
A jammer would be seen in DL only, no in UL.
(as far as i have seen !!!)
UL interference can be seen by looking at indicators named “idle ts interference band” (approx.)
DL quality can be quickly seen by doing a drivetest.
Radio measurements collected by your optim tool shows the rx quality of your cell in each direction.
