Our company is managing the installation of a network in a Casino. The only space available for hardware has two electrical conduits in the 11' ceiling that carry power from the emergency generator. two questions:
1. How can the EMI be assessed prior to installation.
2. Can EMI be screened in any way?

1) Drop a cable down and see what kind of results you get.

2) The best results I've seen with screening emi is wrapping the cable in tape designed for shielding electromagnetic signals.

I have no idea how much of a current is generated in your specific situation. You may need to activate the generator to see what kind of effects it generates.

I've used aluminum foil (wrapped around wires and connectors) with good results on a speaker/telephone system that resided in a computer room as well.
