Decking

Deckers and the matix are the same mechanically.  A large majority of the world is wireless but you can't hack people cars and such because that grid system used in standard SR isn't implement. 

The Matrix is basically the internets, if your phone can get on the nets it can be hacked.  Try to apply the real world to it as much as possible.
