"Corinex is a company that specializes in something called powerline technology. In a nutshell, this technology takes advantage of the pre-existing electrical wiring in your home (or any building) to deliver a full Internet experience just about anywhere you have a wall outlet. The key advantage of this method over a wireless connection is that it cannot be blocked by walls, floors, or ceilings. It doesn’t matter if you live in a concrete jungle; it’ll still work."
