with Medusa and newer radio heads coming that need the high availability
and capacity WHY NOT :)
Already doing this on our towers but I am standing on my soap box about
something new from cambium
that has me with high hopes to integrate it into a nema enclosure just
for this purpose.

If we're changing methods, we should be going to glass and power up
the tower and not use anything conductive for data.

*Subject: *[AFMUG] A Stupid coax question
Comcast has been deploying their WIFI hotspot network like mad in the
Chicago metro. Every public park, gas station, strip mall, hotel, and
train station seems to have a wifi AP hung outside of it now. These
units just hang on their aerial coax cable, and get their power and data
just off a single RG-6 coax run off the nearest splitter. Drawing the
power off the DC Coax plant. Here's a picture of a typical
installation.

So this got me thinking again, as I have for several years, why are we
still using POE to run PMP Equipment on towers. It seems from a
installation, RF Shielding, and grounding/suppression perspective, using
coax would be the far better choice. Anyone can be taught to terminate
a perfect RG6 in <5 minutes. No Colors to remember. Any couplers are
inherently waterproof. No loose plugs or broken clips. Cheap cheap
cheap outdoor cable. Shielded cables by default. It just seems that
there are a lot of benefits for the low power draw radios. Obviously a
licensed link can't pull enough power over an RG6, but EPMP or 450 or
UBNT PMP radios I would think could run just fine. Instead of having to
deal with switching equipment or breakout boxes at the top of a tower,
just run up a larger coax to a splitter. No outdoor enclosure needed.
Is it simply a lack of products that would make development costs too
much, or is there another technical aspect I'm missing. Docsis version
3.1 Full Duplex, which is currently in development will do 10gb sync,
Docsis 3.1 is 10gb/1gb. More than enough for any of our AP Clusters for
at least a few years. https://en.wikipedia.org/wiki/DOCSIS#Comparison
It seems like UBNT or Cambium (heck Motorola already had all the coax
products built) could easily make a 10gb Fiber to Coax adapter for the
tower base. Feed it with Fiber and DC, then just keep adding splitters
and radios until you run out of power budget.
It just seems like I've never heard it discussed, and I'm not sure why.
Obviously there is something I'm missing. Docsis is a standard, but
maybe there's no standard for the power delivery on the coax? So vendor
Inter-op prohibits development dollars from being spent on it.
