Denver, Colo. September 6, 2007 Driving the worldwide acceptance of high-speed networking over power lines, the HomePlug® Powerline Alliance today announced that a number of new member companies at CEDIA have plans for products incorporating HomePlug technology that will further propel the global powerline standard into a variety of new markets.
