Depends what you want?

Electrical wiring usually refers to 120V wiring.

Cat 6 is low voltage (ie not 120V). It is used for phone (unusual nowadays) and internet. Since video is now carried by internet, it is used for that. Since most people are going to have wireless, the need for wire is lessened. But wire is more reliable so can be helpful.

The problem is that install costs are generally pretty high.

My quick story. I wired for a cable modem in an interior office in a slab house. Then from there I ran Cat6 to TV locations. Then I went with ATT and they don't use cable (RG6) so my wiring plan was useless. I had them put a router in an exterior wall and I went full wireless.

To echo David's point it depends on what you want feature wise once the home is built. Generally for most homes I would say: 1x Cat 6 and 1x Coax to each of the bedrooms in what would be mostly likely a desk or TV location. 1x Cat 6 and 1x Coax to the Family Room/Living Room/Den area where your primary TV watching will take place. 1x low voltage enclosure installed in a laundry room/closet or other area to service all this wiring later on. 1x Cat 6 and 1x Coax to the roof for OTA antenna or dish plus net for solar. 1x Cat 6 and 1x Coax from an installed Demarc box on the side of your house near the main cable/phone feed from the closest telephone pole. 1x service mast for low voltage utility connection (assuming the connection is overhead and not underground). Beyond that things get custom to each homeowners feature set.

"What do I need?"

A local electrician.

Electricians can do low voltage, Audio companies can, so can Security. Probably just ask them to see who specializes in it (and will be cheapest). For example, my electrician told me he can do low voltage, but recommended not since all the programming/setup/tinkering/training would take him longer and make it more $$$

You should start with "what do you want your house to do for you"?

• Wifi and/or multiple WAP's if it's a large home
• Hardwired connections for TV/computer/gaming/data
• HDMI can be ran over cat6 - do you need to transfer/split HDMI (security HDR, etc)
• Security system - hardwired cameras use cat6

Or do you just want to run everything over 1 wireless router :)

So to be clear, either a C10 Licensed Electrician or a C7 Licensed Low Voltage contractor can do this type of work. Most of the time the C7 contractor is going to have more ideas on design but that is not always the case. Some electricians know quite a bit about low voltage wiring design. Security companies are not governed by the CSLB like the C10 and C7 contractors are-- the BSIS governs them. A security company has an ACO license but that itself does not give them permission to run low voltage. Either the C10 or C7 is your best bet. Look for a Smart Home Installation company in your area. If you can't find such a thing, go to one of the Whole House control system websites like www.control4.com and click on "Find a Dealer." That should get you a list of companies with the proper licensing.

Wire your home with CAT6A, a little pricy but worth it if you intend to use for 4K or higher TV signal streaming, care about bandwidth and want to use hardwired internet instead of WiFi or want to supplement WiFi, hard wired cameras etc.

We used the following SCP CAT6A for our entire home.

Specs: CAT6 AUGMENTED 10GBASE-T, 600 MHz 23 AWG

SOLID BC 4PR UTP, TIA/EIA-568-C.2,

ISO/IEC 11801 Ed2 CLASS Ea, PVC JKT- BLUE

Run hardwire network (cat-6 or similar) to any location where the device isn't portable (e.g., television, desktop computer, network printer, server). Run coax to every television location. Try to limit wireless use to portable devices only. Depending on the size/configuration of your home, run cat-6 to multiple locations for wireless access points to ensure good coverage.

Try to have a dedicated central home-run location where all wiring will come back to. This should also be where your cable tv and internet is brought into the house.

Make sure testing is included in the wiring bid.

I wired my last house with cat 5e to every room along with phone. No one uses it. My current house project I'm not doing anything. It's all wireless. Find a good spot for your wireless and bring cable/DSL to there. Go underground if you can from road to house. Put a separate conduit for low voltage.
