"Fractenna"
...regarding BPL.

BPL sucks.

Why use HF spectrum when there is so much other, more suitable and much
wider, spectrum available way up the bands? Between improved DSL (higher
speed, much farther, as being implemented in the UK), Cable, WildBlue
(satellite), and soon Wi-Max (35km, 56Mbps), BPL will be nothing more than a
footnote.

In the future, some of those HF users being bothered by BPL might stoop to
doing a quick 'sweep' across the bands. This would cause the BPL DSP
algorithms to think that all frequencies are in local use thus lock-out ALL
the frequency bins and effectively shut down the link for several minutes.

BPL is a REALLY stupid concept. Obviously the HF signal is going to leak
out (and other HF is going to leak in). Dumb. Power lines aren't exactly
twisted pair (close, but no cigar).

BPL has about as much future as Fractal Antennas (none).
