One thing I’ve noticed in the LEED buildings we’ve recently built (2 dorms/colleges and a Physics building), is that the windows block the heat from the sun, which reduces need for A/C, etc. The heat from the sun is just another type of RF, basically. This has a side effect of blocking some, and greatly reducing many cellular signals INTO the building (students have actually had to open the windows to be able to use their cell phones in their dorm room, which causes the A/C to shut off). However, this also means, that any wireless signal going OUT is blocked as well.
The law of unintended consequences.

Good work. Thank you. One question that I have for future reference is: “What constitutes blocking?” You mention White Noise or Frame manipulation… What if building owners have frequency blocking material as part of the design of the building. This could be considered passive blocking as opposed to white noise or frame manipulation but it is blocking regardless. We might want to know the FCC point of view on this before we create “wave free classrooms”!
