They want a stand per radio, with a fiber to universal poe converter on each strand. That way all of their switchgear can be at the bottom. If you replace all of the Lan ports in a syncinjector with sfp ports, then you get the idea.
I can think of lots of other ways to make this work, enough that I wouldn't be inclined to build this except that this is definitely a recurring theme. I think that the idea is that they really want to limit the quantity of gear at the top. If it was me, I'd put either a poe switch up top or a bunch of those ubnt fiber to poe converters, but apparently there are quite a few wisps who don't like this idea.
