    Tried to fact check this but I can’t find evidence that 5g can be blocked by paper. Looks like it’s in 24-28ghz and while it can be blocked with materials the density matters. So maybe like a few books thick of paper but not one sheet?

      Note that this demo takes things over 100ghz. So the challenges associated with mmwave (and wigig) are even more.
