I hope all the patents expire soon and that good products at good prices follow quickly. The standard was released in 2006, but I'm not sure how close to that release date the last relevant patent involved was issued. https://en.wikipedia.org/wiki/10_Gigabit_Ethernet#10GBASE-T https://en.wikipedia.org/wiki/10_Gigabit_Ethernet#10GBASE-T "10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded twisted pair cables, over distances up to 100 metres (330 ft)."

What is pantented about implementations? I’m surprised that the nature of the implementation of a public specification is patentable. I spent a few years implementing 802.3 physical layer testing. At the conferences it was clear that things were written carefully to not cover implementation, but they went so far in the necessary details that there were only a handful of reasonably performant and economical solutions.

  > I’m surprised that the nature of the implementation of a public specification is patentable. Prepare to be very surprised, I guess? It’s pretty routinely done, eg) look at any of the MPEG standards. I don’t know what patents, if any, cover 10GigE, but in general IEEE, which governs that standard, will accept Essential Patent Claims in a standard provided the Patent Holder will provide a Letter of Assurance indicating that they will license said patents under FRAND (fair, reasonable, and non-discriminatory) terms – which does not mean free.

    Yeah I don't think patents will play a major role in the price. WiFi would be a lot more patent-encumbered with technologies like MIMO. Yet it doesn't seem to preclude cheap commodity hardware. My Unifi WiFi 6 AP was only a bit more expensive than the AC one.

10GBASE-T is unreasonably power hungry. SFP+ passive cables are far superior for short lengths and fiber optics are superior for anything longer. I've got two SFP+ 10GBASE-T transceivers on my home network and they seem to sit around 80°C all the time.
