So when is the noise reduction on datajacks applied, Book/Missions Legal Options

[LurkerOutThere]

So I've been thinking about the implication of the wirless bonus on datajacks, the ability to reduce noise. My question to folks is would you apply noise reduction before or after the noise would knock out the wireless bonus on the datajacks themselves.

Lets presume for the sake of the argument that the character in question is close to the source of the noise. Just for the sake of outlining the scenario lets assume that it's a rating 4 area jammer vs an alphaware datajack (device rating 3) who wins (and therefore applies) in this situation.

Bonus round, thoughts on stacking multiple datajacks. There's no rule against it and conceptually I like it a lot.
