PoE has undergone a massive transformation. I remember being amazed when I first set up a VoIP system that ran on PoE—eliminating the need for separate power adapters. Now, I’m working on a smart building project where PoE handles security systems, lighting, and more. If you're curious about the maximum distance of a long ethernet cable before signal or power degrades, this guide has some great insights. Given how much power PoE can now deliver, I wouldn’t be surprised if traditional power cables become obsolete for many applications.
