When I moved into my current house, there were lots of coaxial cables connecting the point in the basement where the cable entered the house to all the main rooms and bedrooms. And luckily there was also a lot of Cat 5 wire left over from the house that was wired into the old school phones and for some reason they used 4 wire Cat 5 twisted pair instead of 2 wire phone wire. So I decided to use Cat-5 instead of coax for the network and also ran lots of new Cat-7 cable for new connectors and security cameras where I could. But if Cat-5 didn't exist, I could very well use a similar product to bring the internet to some corners of my house. I connected a couple of such devices and they found each other very quickly over the network. coax in my house. The speed is good, at least as good as my cable contract: 350 Mbit/s down, 10 up. So it's probably comparable to gigabit at full load. Each device draws about 2 watts according to my Kill-A-Watt. However, I would prefer a passive ethernet cable. First, I have Ubiquiti devices in my house that use Power Over Ethernet (POE) for almost everything, and I don't think POE will be compatible with that. Plus, it only uses 4 watts per pair, which is still more than passive cables use. However, if I want a wired networking device in my kitchen that already has a coaxial connector above the microwave, it would be a lot easier to use a couple of those than trying to run an ethernet cable across the floor, maybe through a fire block and into the spike bay and into this closet. It may well be worth the cost and ongoing power consumption.
