Agreed, and I'd like to see more discussion of that aspect from knowledgeable people.This (the preamble especially) is what _should_ eliminate the motion sensors from the list. I'm out on this one (too lazy to do the math), but is the 802.11b air interface that resilient (does it really require that much redundancy)? It should be, but that would also be some lost (usable) bandwidth.
Sorry. 1) The building will contain very much of that energy (which never was very much on a metropolitan scale, FCC Part 15 and all that). 2) The noise characteristics as received by those services would be intermittent, very bursty and come from many different directions all over the city. No easy clues telling what to complain about there. 3) I don't know about US emergency communication radios, but typical European systems (before Terrestrial Trunked Radio) are so bad anyway that this contributed noise hardly would be noticed.
You may well be right, but keep in mind that the campus police would be operating *in and around* those building much of the time, so they might actually be affected by it, *if* thats possible.
I'm still not convinced that, more than a few feet from a device, the interference would even be detectable.
