Subject: [Qcwa] Powerline Snake Oil
There was an excellent article in last Mondays Christia Science =
Monitor: here just an excerpt:
An excerpt from an article "Power lines set to carry high speed =
Internet." in the Christian Science Monitor, April 26, by Brad =
Rosenberg=20
...Other nations, however, have already made up their mind.
"It's a brilliant idea, but if you give it a more technical, detailed =
look, it all falls apart," says Diethard Hansen, the external chairman =
of the advisory group on BPL to RegTP, Germany's FCC equivalent. "It =
suffers the enormous risk of uncontrolled interference to everyone."
During test trials of BPL in Britain and Japan, Mr. Hansen says, =
interference was so strong that they pulled the plug on BPL.
"In Manchester [England], they failed miserably in the shortwave =
frequency bands because the streetlights started working as antennas," =
he says. "In Japan, they had limited field trials in Osaka and Tokyo, =
and interference got out of control. They had to stop it." Ham-radio =
operators are concerned that BPL will cause the same problems in the US.
But proponents don't seem worried. "What was banned in Japan is very =
old technology," says Thomas.
In addition, Mr. Shark says that BPL didn't work in Europe because of =
an electrical grid that uses more voltage - and a political system =
overly influenced by would-be BPL competitors. "We can't learn as much =
from them."..
