High-tech gadgets need the right wires to perform to their full potential. Just like there are different grades of equipment, there are also different grades of wiring. Voice and data require a certain category, while video needs another. If you want a well-functioning room, this isn't an area you'll want to skimp on. If you're not familiar with coaxial this and fiber optic that, you may want to leave the job to a professional. Also, you'll need to figure out what to do with all the wire, because you don't want it running up and down your walls. If you're building, you can have it installed in the wall. If you're adding to an existing room, hide it behind baseboards and molding.
