[Hidden-tech] Helping others without broadband

[Jim Ussailis]

I don't believe that broadband over powerline will ever make it in 3rd 
world countries for a simple reason.

It interferes with the 3 to about 80 MHz spectrum. So called notch 
filters have been tried with dsome success, but notching a band of 
spectrum does reduce Fourier components of the signal, thereby reducing 
available bandwidth.

The problem is 3rd World countries use / listed to / get news from 
shortwave radio. Some also use lower frequencies for communication since 
it is cheaper.

Although the amateur radio community in the US and Europe has raised a 
fuss about BPL, the viability of it will depend on profit. Apparently 
that isn't there.
