Hi Matt
well, for sure the classical telco is -48V but lately I did not see
any WISP product running in the 48V arena.
Maybe I should check mikrotik but I do not rember any new mikrotik
product running at 48V.
by the way: does the ubiquiti titanium works with -48V? I see 48V and I
am
It's best to get an isolated DC-DC converter to move from +48 to -48. The
Titanium is 802.3af compliant, which I believe is +48v.

Hi Mike
do you know any good DC-Dc isolated converter?
Or maybe it could be easier to find some +24V to +48V converter
Thank you
Paolo

I just wanted congratulate the wispa org for doing their members proud.
I was not able to attend due to knee surgery, but in a whole lotta
years of hearing about and attending conferences NEVER have I heard so
much praise about an event of this size. Specially with such a diverse
membership.
That has been true, but it seems like the cell world has been moving to 48V
lately.
Examples:
Alvarion carrier WiMax (2.5Ghz), macro and micro uses 48V (maybe you can
get it in 24V, the stuff I've seen has all been 48V)
With packet optical, if you put a Cyan box in that uses 24V you
need separate
All the LTE gear we have researched are -48vdc

Has anyone used one of these to 'upgrade' a site to 24VDC while keeping it
24VDC?

I have used one to go the other way, 48 VDC in to 24 VDC out, on a TSI
UPS/PowerSupply and it has worked flawlessly for 2 years in an outside
enclosure.

Gigabit Ethernet requires all 4 pairs, so passive PoE wasn't an option.
If using active PoE, going with 802.3af makes more sense, and its 48v by
standard.
I don't think UBNT was trying any lock-in with this move. It was this way

Yes. But not that large. We use the 7 amp version with the fan for all
microwave installs for cell carriers. Metro PCS is one carrier that has 24 vdc
power plant. We use the larger unit so it runs super cool. Never had a bad one
in over 5 years...
