Is this just coax as backhaul? Or is signal actually emanating from the shielded coax cable? I haven't had my coffee yet.

  It's sticking the Wifi antennas at the end of a long cable. A "feedline" in the usual terminology. How this interacts with beamforming and antenna diversity is .. not specified. The basic idea seems simple enough: rather than stick an AP on one side of a wall and accept a 15-20dB loss through the wall, or use two APs, cable one antenna through the wall so the AP has a clear line of sight on both sides of the wall.

    That was my interpretation as well. I feel like this is another case of someone new to the industry creating a “standard” for something that, had they been around for a few decades, they would have realized already existed in a different context. Case in point: we have had “external” uni- and omni-directional antennas, even for plain old 802.11, for decades.

      Isn't this exactly reusing old technology that has existed for decades (well, over a century now) in a slightly different context? I mean, a lot of pre-existing coax is there exactly for the purpose of running a signal between an antenna and a device…

        Of course. But would you call that “WiFi over coax”? No one I knows would...

    Honestly if I'm running a cable I'd rather run PoE over RJ45 and just have a second AP. PoE powered APs are cheap enough these days.

  No I think it's like running a (coax, as well) cable to the television antenna on your roof instead of having rabbit ears sticking out of the back of the box.
