I am curious if there are any implications for the Russian invasion of Ukraine from this tactic working.

What do you mean, Russia has been doing the same thing for most of the war? The success relies on you controlling the territory, or at least territory close enough, so the results vary.

In a war zone any large high power jammer will be like supernova in the darkness visible for detectors from tens of kilometers away. So its gonna be immediately destroyed.

Iran protesters cant find or destroy jammers though.

Isn't Iran doing this from the air? That would be far more effective. In a contested space with AA everywhere that wouldn't be feasible (i.e. large parts of Ukraine)

> What do you mean...

I am an RF ignoramus. It all seems like black magic to me. I have seen "80% packet loss" being thrown around in these discussions, and also that it is just GPS spoofing.

My main question is that is there anything novel happening here? What is the actual range of disruption?

Both sides are using starlink, yes?

Also there's now guowang to contend with. I'm not sure how widely available access to it is.

I would assume both sides are heavily jamming the frontlines. But presumably long range drone operations are more likely to use it.

Jamming is subject to the inverse square law.

Yes, this is why it happens only on the front line

I don't think it will have much implication. Jamming is a two way street. You can erase some spectrums, but you are also creating massive electromagnetic beacon for home-on-jam ammunition.

However if you are a protester without any advanced weapons, then you can't do anything against that.
