This is interesting you bring this up. I've had discussions with other folks who think that fiber will one day take over wireless. I think it's a case by case basis where no one technology rules them all. In some areas, such as your remote location, wireless may be more cost effective to deploy since there's no need to put poles in the ground every few hundred feet.

In extremely dense areas though, like down-town Phili, wireless may or may not work as well as Fiber due to the sheer bandwidth requirements and limited spectrum.

Doesn't OnStar use the cellular network to communicate information back to the "mother-ship"?

I find it hard to believe GM is actually footing the bill for all of these cars when the end-user isn't paying the on-star fee.

Can anyone explain how this is working?
