Douglas, those aren’t bad points, but after years now of the IT field having to deploy and support wireless access points, I think it’s become pretty evident most in the IT community much, much prefer 802.3af/at compliant radios than having to use injectors with 24V radios. In the community forums where this has come up, almost everyone agrees. Especially for edge devices in remote or off building purposes. You can’t reboot a WAP remotely when it is hung up and on an injector, unless you go through the extra expense of putting in an IP enabled PSU, too. And while in a perfect world field techs should know not to plug 24v passive POE radios into active 48V POE switches, experience has born out this is far from a perfect world.
I can see where the power requirements for 24V Passive might be advantageous for some applications, like solar power and mobile vehicle power applications. But ironically, that would be niche use case that would be a small % of what is desired for the majority of applications.
So what we’re seeing after decades of experience now is 24V Passive should be more of a niche use for a smaller number of deployments while the market prefers more native 802.3af devices. Ubiquiti seems to be the only manufacturer really taking this seriously. They were one of the first to offer in inline convertors so you could attach 24V radios to 48V POE switches for the entry level radios. And one of the first that I saw to start offering entry level radios with native 802.af support. It’d be nice if Cambium and other manufactures could ramp up their competitive offerings so we don’t have to always be circling back to Ubiquiti.
