Leaders of the power line networking space say that Wi-Fi's success in the home helps the power line networking industry: A spokesman for Intellon, which makes power line networking chips, says that the dead spots that result from many Wi-Fi networks in homes create an opportunity for power line networking, which can be used for network access in the dead zones. HomePlug, the alliance of power line networking companies, is also hoping to get ahead of its networking competition with a new standard it is working on that will be fast enough to support high-definition TV.
