Re: New homes lack wired ethernet

nevtxjustin@xxxxxxxxx hath wroth:

In spite of the FCC requirement that homes be built with structured
cabling, I still see it negleted in $300,000 - $500,000 homes. I asked
a contractor about it on one house and he said that everyone uses
wireless. The house was wired with 3-pair untwisted cable, one more
pair than the old 2-pair JK ("Jake") telephone wires from the '50s. In
another house the wall jacks were marked as CAT5, but the CAT5 cable
in the attic had wire nut splices.

These are the home owners that often post here about how they can't
get a wireless signal in their new house.

Rant mode back on.

It's worse than you think. I got a call from a local electrician
asking what type of wire to install in a remodel. I think I repeated
CAT5e several dozen times. I supplied a printed list of connectors,
jacks, and wall plates. I supplied a diagram showing how to run the
wiring (home run where everything comes to one place). We discussed
the location of the "electronics cabinet", how not use a staple gun,
and code requirements. I was fairly sure he understood what I was
saying.

However, he sends some kid over to the local electrical supplier, who
decides that it's all being done wrong. He gets 6 pair telco wired
(forgot what it's called), SOIC RJ-45 alarm jacks, incompatible wall
and plates that don't fit the jacks. He then runs the cable in "daisy
chain" fashion, suitable for telephone wiring, and leaving perhaps a
2" service loop. Of course one can't waste wire by extra CAT5e
cables. All the junk wire is stapled to the studs in the wall. That's
being generous because they were stapled to the studs with flat
staples, which broke or shorted at least one wire in each section. Of
course nobody called me in to double check until after the drywall was
up. Naturally, the home owner considers it my responsibility to "make
it all work". Right.

I wouldn't complain too much except that variations on this disaster
have happened about 4 times in about 15 years to me, each with a
different electrician. Lack of networking knowledge may have been a
good excuse perhaps 10 years ago, but in these days of commodity home
electronics, it just doesn't cut it. Of course, none of the
electricians were BISCI certified or they might have known better.

These days, I'm sneaky. I specify corrugated electrical flexible
conduit (PEX, XLPE, or HDPE), with no wires installed. It's more
expensive, but far more versatile when the owner wants to change
everything and cram in CATV, fiber, telco, etc.
