Plan for PoE(power over Ethernet) wireless access points on ceiling
As the number and capabilities of Internet connected devices continue to increase, so do the demands placed on residential wireless networks. For a home more then 2 floor, a single router in your basement or wiring closet is no longer powerful enough to handle the strain smart devices place on a network. Everything in the future from your lighting, shades, curtains, cameras are going to be powered by wireless devices. Therefore, we recommend planning for at least multiple wireless access points based on the size of your home.
Instead of using a power outlet, Wireless access points (WAPs) can be powered with Ethernet. No special cables are required as long they are CAT6 cable and fire rated for in-wall use they will do the trick. This is referred to as PoE, or power over Ethernet. By running a few Ethernet cables to various locations in your home, you’ve already set up yourself to expand your wireless range with PoE WAPs.
All new homes should be wired with Ethernet, those wires are usually ran to the same location as cable jacks or AV equipment to a desk or TV/Media Closet. For access points, Ethernet cables are run to a location on the ceiling further away from the walls.
All the wiring should go to a centralized location with power feeds. Typically they are located in the utility room where your cable to DSL line comes into your home.
