Weirdly, though, noise not from distance is only applied at the source by RAW; at least that seems to be the the calculations are made in the book.
And if you apply noise from both the target and the destination you end up with potential heaps of Noise, which also seems odd as a person using a deck in a -5 spam to hack another dive in a different -5 spam zone that is halfway across the world for another -8 would suffer up to -18 noise. The book only applies one of those spam zones, and that's the one that affects the device you are using. So in the above example, a satellite link would reduce noise by 3 to the minimum of 5, and then you could move yourself out of the spam zone you are in for another -5 reduction, to the point where you're only facing -5 for distance, which you can easily counter, even if the device you are targeting is in its own -5 spam zone.
