Wait. The entry for sattelite link does not specify "Noise Reduction", is specifically states:
"This link limits Noise due to distance to –5."
Noise due to Spam/Static zones are Situations, not Distance.
Sigh...Are we going to discuss satellite links now...??

Satellite Links It let you connect to the matrix from places where no local wireless networks exists. This is the
primary reason why you use a Satellite Link.
Using a Satellite Link IS a Static Zone situation.
Check p.231 Static Zone modifier: "Remote place with satellite access only": Noise Rating 5
If you are in the middle of a desert, the north pole, adrift in the pacific etc. you will not have matrix access
at all -unless you bring a satellite link.
In
addition Satellite Link have the added benefit to limit Noise due to distance to -5, as per the description of the device at p.439
That mean you get a flat 5 noise rating if you hack through a satellite link no matter how remote you are (even if you are in a middle of the desert; which would normally totally prevent access to the matrix) and you never get more than 5 noise due to distance no matter how far away you are (other side of the world; which would normally give you 8 noise).
@Xenon: I am going with enough noise fully eliminating all wireless functionality, including communication myself. The rules state wireless functionality, not wireless bonuses. As such all wireless functionality is gone.
The alternative reading, by the way, means there is no reason for a Rigger to ever provide a Drone with Noise Reduction unless they're Jumping In. Nor would smartguns lose their connection with the smartlink, nor can a team communicate with their commlinks anymore. This last part, by the way, is contradicted by Ashes: In there, they only can communicate through infrared and wires because of jamming.
So honestly, I think the impossible consequences of another reading prove it's not supposed to be read like that. There's no way Jammers are worthless against Commlinks, Drone Control and Wireless Grenades.
I have a slightly different approach at my table. I don't think snow, heavy rain or background noise etc. should cause augmented reality to fail. That entire mesh networks (the Matrix) will stop routing traffic.
However Jammer on p.441 state that they
"floods the airwaves with electromagnetic jamming signals to block out wireless and radio communication."In my opinion this is the primary reason why you use a Jammer. A
secondary reason is that it
also provide Noise rating -even if it fail to completely block out wireless and radio communication.
ECM might be something future books introduce, but we already have the Electronic Warfare skill (which you can use for disruption and even have a Jamming specialization) and we already have Jammers. We also have rules that cover ECCM in the rigger chapter (which let you use Electronic Warfare to get better signals and avoid being jammed - the skill even have a Communications specialization).
This is how my ECM house rules look like:
When you use a jammer for the purpose to disrupt wireless and radio communication you make a Electronic Warfare(Jamming) + Logic [Jammer Rating] test or a Electronic Warfare(Jamming) + Logic [Attack] (if you use a cyberdeck as a jamming device) and note number of hits. This will act as a ECM rating for all devices in the AoE. Note that as Jammer Rating is reduced over distance so might your hits as Jammer Rating act as a limit - and with this the current ECM rating.
All noise reduction in the book (wireless data jack, signal scrub, taking a complex action using Electronic Warefare(Communications) + Logic [Data Processing] on a RCC, increasing Noise Reduction at the cost of Sharing on a RCC etc) will provide equal amount of ECCM rating.
ECCM rating is added on top of the device's rating where it run for the purpose of jamming all wireless and radio signals.
If ECM rating is equal or greater than a device's rating (or rather it's current Data Processing rating which is normally equal to it's device rating) + ECCM then you jammed a device's all wireless and radio signals. To block communication between two sources, ECM rating need to be equal or greater than the highest rating.
Or if you turn it around; Target device's rating + it's ECCM act as a threshold on your Electronic Warefare test.
A lot of text; but basically you roll electronic warefare + logic [jammer] and if you get 2 hits you will block all communications from almost all devices, including mental commands to detonate a wireless triggered grenade if the thrower use trodes, but you need 3 hits to block wireless DNI communication from users that have a data jack as the data jack provide 1 point of ECCM.
