the Ubiquity converters work on Cambium radios (except in a specific set of older radios which are not polarity agnostic).
If your techs are doing things like not checking the power type before plugging in, then that is an education issue. After 20+ years in the IT world as a professional and the past 16 working with Ubiquity, Motorola/Cambium, Early Mimosa, Microtik and the old AeroNet and WaveRider systems, education and understanding is paramount.
They make 48v solar panels too, these are industrial grades. Same panel just configured differently.
The problem comes to powering other devices. Most devices are actually 5, 12 or 24v inside their cases so it makes sense to not add an additional component to the device if you dont have to. That 802.3at converter has a fairly high cost as it is a licensed technology, this would increase the cost of the radios.
The dedicated APs that Cambium puts out are 802.3af/at compliant. So right product for the right need? Using a SM in AP mode is not the standard but the exception to the designed use. And since the epmp line is not a WAP, its a bridge (ptp or ptmp, but still a bridge), comparing to a WAP is wrong.
Now for the cnPilot line, these are WAPs and should be powered by 802.3af/at and should be able to be powered on passive 24vpoe. These may need to be two separate product lines for the same radio. It is nice being able to put up a solar wifi spot in a park connected to the epmp network and only have one voltage to worry about.
IP enabled PDUs are nice but expensive. You can get IP enabled injector with local system monitoring and autonomous action that works on your chosen system voltage (packetflux site monitor system). Yes these are expensive too, but when on battery run time is important and allowable battery bank dimensions are restricted, double converting your battery voltage to standard 120vac and back to 48v (56v) DC just to be reduced again to 5, 12 or 24v is very wasteful and reduces your available runtime from days to minutes. This is why UPS systems do not run for hours until you get into datacenter size UPS systems.
And while we are quoting “standards”, it is apparently standard to go with whomever has the feature of the day for hardware. Running to Ubiquity because they have the one thing you want regardless of the actual quality (still can believe they still dont properly shield their radios) is a personal preference. You still prefer Ubiquity so they are your go to.
My main competitor is a UBNT shop, yet I keep getting their customers switching to me whom is 99% cambium based (I still have a few non-cambium Wifi WAPS in place and am not changing them until they die). Dont get me wrong, I have my troubles too, I come on here and see whom else is having the same or similar and complain when and where needed to. So far my complaints have been addressed or in the case of a couple, they were incorporated in the next edition of hardware.
I am not disagreeing with you and your stand point, it is valid for some of the product line. Which is why Cambium has made it possible for those products, but they have also seen what we the WISP community has been doing and how. This also drives what they offer. Deciding something s niche just because your experience says it is doesnt reflect the reality. Then there is the regulatory side of things, technically any cable that is to be carrying a voltage over 30v in Canada must be installed by an electrician with a permit. All connections must be made by said electrician too. Now there are some exemptions in place for data and telecom, but you cant rely on them as at any time an inspector can come in and order a stop work plus fines for non-compliance.
Like most things, there is always more to the issue than what we normally see and experience. So take this as just what it is, my point of view and nothing more than engaged conversation.
