It's the first rule of communication. Know your audience.
A "rules forum" by default will likely assume "the rules" as the subject, unless you specify otherwise. This is because the rules as written serve as a common base of discussion that everyone is familiar with.
It's fine, even welcome, to discuss other stuff, but generally one shouldn't assume that others will realize you are not just discussing the default subject anymore.
This isn't meant as an attack, just friendly observation. Being clear will only serve to enhance your commentary. Not being clear, on the other hand, well...
As for the discussion at hand, I will agree that the range on area jammers and ECM are just too short. I suspect whoever wrote the rules was only thinking in terms of street level combat, not vehicle scale.
Also, RFIDs really should be Signal 0. 40 meters effective range seems awful long for pinhead sized transmitters.
