my best bet is that VLF/ELF frequencies are using FFT (Fast Fourier
Transform) algorithm to increase compression ratio of WLAN devices
operating with OFDM-enabled hardware. If that is true then not all WLAN
devices
can do OFDM thus explaining why you could use 802.11g without it...

Hi,

your post mentioned ELF/VLF radiation, thats electromagnetic waves the
frequency range below 30kHz.

How should a modulation scheme (OFDM) used in the 2.4/5GHz range be
related to radiation in such a low frequency band?
