A correction, some additions and a short allegory

o) I'm using 4 APs for 1800 sq ft, but it's two story stacked like two
blocks, so the radius per the RF spray pattern design can (and does)
take advantage of that
o) I placed high quality UPS where needed
o) I didn't mention IoT like irrigation control, PV monitoring,
weather systems, etc. Those are managed by a RPi4 with a UPS board and
battery. Scripts and c - code is written by me.
o) I didn't mention my in home lab/work network where each test device
has it's own GPS signal to get pulse per second from those atomic
clocks. That really helps a lot in my iperf 2 work
o) Having an in home lab gives me back an 30 minute commute (or 1 hr
for both directions) which is a lot and adds up. Unfortunately, my CEO
thinks we're children and need to follow an attendance policy so now I
have to waste time driving to do emails and get an attendance credit.
I started working at age 13 at a Baskin Robbins and within a month the
immigrant owner asked me to run the crews so he and his wife could go
home and rest w/o worrying about their primary means of  income. It's
very sad to be treated like a child, even when a child. SV is run by
children's mindsets now.
