Links between cabinets at commercial datacentre

Unnamed Administration sources reported that Rubens Kuhl Jr. said:

Are there any rules preventing radio transmission on ISM bands from the
cabinets ?
You could reach other cabinets from yours with wireless LAN...

For any reasonable bandwidth, laser links would be needed.
But I suspect the management would just pump smoke in.

You're fighting an attitude. They'll change the rules
as needed to screw you.
