New construction in "technology ready" homes is five (5) coax feeders into the main distribution panel plus a fiber innerduct (smurf tube) between the panel and the MPOE. Distribution to "standard" outlets is 2 coax (rg6 quad-shield) and 2 cat-5 or cat-6. Also 1 coax & 1 cat-5 from above every outside entrance for video surveillance. Finally allow one spare empty 2" diameter smurf tube from the attic and/or basement into the panel as well. This allows for future expansion after everything is buttoned up. Cap-off all the smurf tubes to prevent God's crawling creatures from entering. Don't forget prewiring the surround sound system. Do not put the surround wiring in the main dist. panel. Make audio a separate project and don't get stupid on wire size. #12 stranded copper is plenty. Also put a coax run for the subwoofer. The distribution panel should also have a duplex power outlet. Don't allow anyone to split your CAT-5 cables for mixed services. If you put voice in it, then it needs to be considered a "voice" cable. Ethernet is an 8-conductor cable when you allow for POE. It also is not spec'd to have two Ethernets running inside the same cable, or putting voice in the same cable as Ethernet, so don't cheat. Save time and money, use cat-5 E stead of cat-6. Neither one is spec'd for gigabit speed and there's no standard speed between 100 Mbps and gigabit, so don't waste money of 350 Mbps cable. Properly installed Cat5e will run anything that cat-6 will.
