CNN estimates that smart homes will grow from a $10 billion business this year to a $44 billion industry by 2017. It will happen because there will be no more thinking about Bluetooth or Wi-Fi or broadband, the smart home hub will eliminate the chaos. Smart homes use mesh networks, so there is always more than one way that a command can be received, even over radio or electrical lines inside the walls.
Looks like contractors will need new skill sets or a new set of subcontractors.
