[nflug] wireless access point

[David J. Andruczyk]

NOTE: a perforated faraday cage  will block/shield
only a PORTION of the spectrum.  that portiona is
determined by the geometry (hole size) of the cage,  
bigger the holes, the higher the frequencies that GET
THROUGH  (like wifi, which runs at 2.4 Ghz)  a solid
cage will block pretty much everything (depends on how
"tight" the cage is (small openings can leak a
surprising amount of RF)  Steel grid mesh may block
AM/FM radio quite well,  but not necessarily wifi.
