From what I can tell, Boomstick, the idea generally has nothing to do with connection speed.
Well, yeah, but then I don't see why reaction enhancers can work together by wireless and not by any other connection mean.
And If I had something connected to my nervous system, even if not a hacker risking encounter with IC (yes, I know it changed, but I'll stick to this for now), I would not take the risk of it taking a virus. And no designer of a combat implant would, while it is not practical for the audience it is aimed at. Special ops? Army men? Indeed, they never want to do covert ops. SO I will design it the less efficient way for all uses, while it would be so simple to interface both things at brain level with nanowire or anything less open to mind rape and nose bleeding inducing nastiness, catatonia and paralysis (because what happen if wired reflexes are hacked? Don't just lose the bonuses I guess. If you can make happen actions for guns and so on, imagine what can be with neural implants...).
Indeed, rather with the utility of having a device designed to constantly access the matrix connected to the matrix.
If it makes you feel any better think of it as Ares version of the XBone.
Doesn't help so much:)
Actually, I would like the idea if it made sense. The example quoted of the Ares Alpha correcting trajectories from windspeed could justify need of Matrix access, but actually I am not sure there are precise windspeed meters any other locations where the runner is or where he is targeting at. But according to the rules it is no problem, if he has not enough noise to shut the device, and if he is connected to the Matrix.
And Satellites can give only tendancies. So it won't make sense a lot in some situations neither.
