Interesting topic.
Eight years ago when I built this house, I spread 1,000 feet of Cat5e throughout. A good majority of it from various places in the HT room to the main equipment rack area. Also, made runs from most of the rooms in the house to a centralized closet in the basement. My thinking was "eventually", I'd run
whatever without breaking a sweat.
Along comes WiFi.......Ended up using half the cable for phone, the other half just dangles not doing anything.
Would be cool if it turns out I could use it and find out I was having a good idea eight years ago.
