God, but I'd love if this could be true. However, as others have pointed
out, there are those of us who do have some idea what this is about
technically. To make a simple analogy - 10/100 Mbit/s Ethernet over
twisted pair needs a high quality cable with two wire pairs (one for send,
one for receive) and at that, its maximum reach is 100M (maybe Cat. 7 (or
is it 6 ?) reaches further). High quality in this case refers to the
components of the wire, as well as to its fabrication i.e. the twisting of
the individual wires is important.
In any event, this cable is of much higher quality than any installed
local loop telephone cable. A fundamental law of information transmission
tells us that sending 45 Mbit/s requires a signal frequency of at least
90MHz and 100M of cable with a 90MHz signal is radiating like hell - this
is what the high quality cable and twisting is all about. I'd be as happy
as a ping in manure if these guys have managed to prove Shannon wrong, and
if they're willing to commit commercial suicide by offering a product
1000x what's currently available for the current price, but like many
others here, I hae me doots.
