The
intention of this site
is to provide resources for those tasked with designing,
maintaining or using a SCADA radio network. The site is
specific to the
radio frequency based communications medium. User owned SCADA
radio
networks require some initial intelligent design, but
can
afford the owner a very robust and exceptionally reliable
communications network.
User owned systems can achieve minimal down
time measured in minutes
per year vs. weeks after storms, power failures, cable cuts, etc.
The
user owned SCADA radio networks are totally controlled by the owner and
his maintenance
organization, Vs. Telco, cable, or wireless communications
carriers.
Proper design and control of your spare part program can make
an outage
be as simple as swapping out
the damaged part.
The industry standard for designing most SCADA radio links
is 20 dB
of RF
fade margin. This is
additional signal is designed into
the link budgets for each radio path. What this means is that
there is 100 times the minimum amount of
RF carier signal
needed to properly signal the radio link to transport the SCADA data on
it.
Decibels
are logarithmic and a little goes a long way to provide reliability.
For radio links there is often more than 20 dB of RF
carrier
signal, which makes these links even more reliable.
There
are countless SCADA radio networks through out the United States and
abroad
monitoring and controlling everything from municipal water and waster
water systems, to oil and gas production, power grids, transportation
of
and much more in between. These SCADA radio technology based
communications
systems have ranges from yards to hundreds of miles.
Selecting the right technology and
defining the projects requirements, and creating a
solid SCADA communications network is crucial.
If you have any questions or 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 organization is often used to subconsult with
consultants, assist controls system integrators, and work with the end
users directly.
