Jamming is another, good call.
Spam and static zones are others, but they apply equally to everyone and all devices, so are not relevant to the discussion at hand (which is, to my mind anyway, about noise affecting one device but not another).
The jammer you listed, which is how this topic started, is a perfect example.
A R3 jammer is enough to overcome the smartgun, but not a R6 commlink; if you have communication between the commlink and the smartgun then the smartgun should still be able to access the Matrix through the commlink, as per the whole mesh topology idea. Particularly as "The Matrix" is the abstract of every device out there, and not just a single device.
Since you brought it up, though, I think it's odd that a sattelite link would not give you Matrix access in a wilderness/rural area; I've used satlinks in Afghanistan (which is plenty fucking wild and/or rural), and they work just fine...

Michael; except that it is not stated in RAW that a device has to connect to "The Matrix" by itself. The way the matrix is designed is exactly as I've described several times, which is as RAW, and that is that every device is the matrix. So my smartgun doesn't need to connect to some obscure device, it just needs to connect to the closest device that does have access to the matrix.
The rules state:"Because nearly every piece of gear and ’ware is wireless capable, it means nearly every piece of gear and cyberware benefits dramatically from being “meshed” into your wireless personal area network and the Matrix as a whole." (page 421)
So, each device in my PAN can speak to each other, and through each other, to the rest of the Matrix. Agreed?
"When an item has additional functionality when connected to the Matrix, it’s described under the “Wireless” entry in the item’s description. This functionality only applies when the device has access to the Matrix, which is most of the time unless your gamemaster says otherwise, like if you’ve entered a wireless static zone." (page 421)
When the device has access to the Matrix. It does not specify HOW this access is obtained, merely that it needs to have it. However, the previous statement specifically describes the device being "meshed" with your PAN as being connected to the Matrix.
And yes, a wireless static zone could possibly negate such connections. This is where I think universal access cables come in, though. More on that below.
"If there is a Noise Rating from a situation that is greater than the item’s Device Rating, not including distance, the item temporarily loses its wireless functionality (see Noise, p. 230)." (page 421)
Again, Noise has to exceed Device Rating specifically; static zones would do it, as would some of the other situational noise ratings (like saltwater), but not all of them.
"These benefits only apply when the item’s wireless mode is on." (page 421)
Nowhere is it stated that a device cannot be wireless on AND have a universal access cable attached...
Now, going back to sattelite links, I just noticed that the Spam and Static zones mention these;
"Commercial area in a sprawl/Remote place with satellite access only: Noise Rating 5" (page 231)
That has got to imply that a sattelite link would negate this type of noise rating, surely? Is the wording of sattelite link just poorly worded?
Also, on wired connections (page 232):
"Devices have a universal data connector, which is the global standard for connecting devices together for power and data exchange. If you have a cable, you can connect to the device directly."
"When you use a direct connection, you ignore all noise modifiers and modifiers due to being on different grids or the public grid. It’s just you and the device."This is important, I feel, because it doesn't state that the device somehow is disconnected from the rest of the Matrix when you jack in with a UDC, it just states that for the purposes of communicating between you (your device) and it (the other device) there is no noise and you ignore grid modifiers.
How does that preclude an item from obtaining a Wireless bonus by "being connected to the matrix" through a UDC to a device that is not affected by the Noise Rating? It doesn't, at least not by RAW.
