Direct answer
Yes. Wireless devices still depend on a wired network, power, and well-placed access points. Wi-Fi is ideal for phones, tablets, and mobile devices, but fixed televisions, access points, cameras, controllers, and high-demand equipment often benefit from cable. Power over Ethernet can deliver data and power to supported cameras, interfaces, and network equipment over one planned run.
A wired backbone reduces unnecessary radio traffic and gives the wireless layer a dependable foundation. The strongest design is usually hybrid rather than all-wired or all-wireless. CEDIA's wiring guidance identifies wired infrastructure, PoE, room-by-room planning, and centralized cabling as core practices for a reliable, scalable home.
