The problem with a wall mounted solution is that the antennas are in a

as much air-gap isolation from the lines as possible. That leaves
wireless, FSO (free space optics), and fiberoptics as the available
options.

It was plugged into a high outlet just under the ceiling and line-of-sight, perhaps 30 feet from the node. Keep in mind that this is a hospital basement built in the 1930s before any sort of computing of any nature. The footprint is an entire city block.

We are thinking that the main router has some means of blocking these things out. Is that possible? The nodes are all hard-wired.
