Fred is remodeling his home and he's got open walls right now. What cabling should he install so he's set for the future? Leo says he should install Cat 6 Ethernet cable. That would really future proof his home with fast data networking. Or he could just go with wireless networking. He should at least run conduit in the walls and as the technologies change, he can then reinstall whatever cable he needs. Fiber optic cable is pretty cheap, but the switches are expensive. That's why Ethernet is still the best way to go.
