Plant & Facilities Engineering

Greetings.

You have said it yourself wireless is susceptible to outside frequencies.

It is also susceptible to outside monitoring.

It is easily susceptible to an outside source blasting your wireless with frequencies that will leave your plant totally down and without computer control.

You will be leaving your plant easily open to espionage and being held hostage by outside sources.

Wired telecommunications will solve most if not all of that.

Keep It simple.

Wire your plant.

Don't give access for your plant computer operations to outside of your plant. In other words have an internal system to run the plant. And have a system that has access to the internet outside your building. Don't mix the two.

I have been involved with computer espionage and it sometimes comes from within and sometimes from without and sometimes both combined. Two systems makes it easier to find.
