A
well respected RF engineer close friend of mine shares his creed with
me,
"design first, then you build". Seems ridiculously simple,
but
this simple concept is often overlooked when creating a new SCADA
system. I have seen these oversights cause pain in budgets
and
frustration in other areas like scheduled turn up dates. When
it comes to SCADA radio networks we must design first.
We
can't see radio energy with the naked eye, we have to use tools to
measure how well our intended RF signals can and will travel.
We have to use tools to do this and look for
possible interference
sources in and around our intended RF spectrum.
When these tools are employed to confirm or fine tune a SCADA
radio network design, it will allow us to build your SCADA radio
network with a high degree of confidence. The process of
verifying a design is called a radio study or propagation study.
it is the subject of the next section, and can be an
invaluable resource.
If
you have any questions on a specific project or an application you
would like to discuss, please
feel free to call on
me, Mark
Lavallee. I enjoy sharing my 20+ years of experience and
knowledge. My company is often used to sub consult with
consultants, assist controls system integrators, and work with the end
users directly.
