Linksys Incorporates HomePlug Networking

Posted by Hemos on from the cool-new-tech dept.

mattyohe writes "It seems that Linksys is one of the first to prepare release for their ethernet router that uses the HomePlug 1.0 spec. Linksys claims the Instant Powerline EtherFast Router performs well by using the OFDM (Orthogonal Frequency Division Multiplexing) scheme. OFDM forms numerous signals into a single signal for transmission and then is used again to find and automatically adapt to the specific frequency combination that enables successful communication. This product currently uses 56 bit DES encryption and would be excellent for networking in the home enviroment. Never worry about not having enough rj-45 jacks at a lan party, bring some power strips!"

    Aw, c'mon. Insightful? It's easy to build a highly regulated DC power supply from arbitrarily noisy AC power mains. High capacitance, quality power transformers, noise chokes, power entry modules: all these components on a modern power supply are there to filter out noise. In low-power components like DACs and preamplifiers, the regulated power rails should have a VERY high noise rejection from ~0 into the low MHz. IC regulation isn't practical in power amplifiers, but really impressive capacitors are practical and a good design will have power supply noise well below signal level or throughout the audible band.

    In other words, I wouldn't sweat it for audio uses. If it really bothers you, power your audio equipment through a real UPS with a lead-acid battery and inverter. That should brick-wall filter any noise from your mains.
