If the non-cyber gear is connected to the Data Jack via cable I'd rule they'd get the Wireless bonus without being wireless. I gotta think that would be mostly sensors, but YMMV.
Smartguns need to draw data from the outside world sensors, windspeed, is it raining, and what not in order to work. Smartgun links are chatty little things from my reading, if they're not wireless ON, no wireless bonus dice. All IMO.
So, to Darzil's point, lotta GM calls.
The more I think about it, the more I want to call bulldrek on the smartgun thing. If they relied on drawing data from the matrix on environmental conditions, then smartlinks would be useless indoors, since the temperature, humidity, air pressure, and directional air flow are totally different from local weather data. There is literally nothing the internet can tell my gun to help me shoot someone in the chest from 12 feet away in the hallways of a burned out building in the barrens.
It is one of those things where you do just have to suspend a point or two of disbelief to keep it playable. Otherwise you will be bogged down trying to decide, would this area provide a bonus or not?
Likewise, wouldn't you think the corps would somehow lock down any devices providing this sort of data within their own territory, or at least encode it so YOUR smartgun couldn't easily access it while THEIR smartguns could?
Again you would fall into the pit of arguing code cracking and such, although if you play with this idea then a decker in the group actually could be a necessity since he could be cracking these enemy data streams to feed the party's battlenet and provide said bonuses.
But that is for more advance style play and again can get bogged down at times.
