Ed is building a house in a remote area. Should he install Cat 5e or Cat 6 cable? Leo says that the faster it is, the more expensive it is. It's about 30% faster with each level. So Leo says to future proof your home, buy the 5e, but he should put in conduit so he can replace it with faster cables down the line. It won't speed up internet access, it'll just speed delivery of data within the house. Most people will just be using Wi-Fi, though.
Avis is remodeling her home and she wants to wire her home for three computers, security cameras, and her home theater. Leo says that will require a high speed connection with all that video data. It's hard to future proof, but as long as she has the walls open, she should put conduit in. That way, when she needs to upgrade, it's a lot easier to run new cable through it.
