Riding the sine wave - Sending data over power lines is not a new concept.

Riding the sine wave Sending data over power lines is not a new concept.

"Others weren't quite so taken with the news.

Manassas citizen, engineer, and ham (amateur-radio) enthusiast George Tarnovsky stated, 'This entire BPL system is a failure.' Tarnovsky's point focused not only on emissions from the BPL system that interfere with ham operations, but also on interference from hams and other sources to the BPL system. He continued, 'They have no ingress protection.'

Sending data over power lines is not a new concept.

The HPA (HomePlug Powerline Alliance) has for years touted power-line-based home networking, and HomePlug 1.0 products from multiple vendors offer 14-Mbps maximum data rates although actual data rates are in the 5- to 6-Mbps range. New HomePlug 1.0 Turbo products are just emerging that extend the maximum speed to 85 Mbps.

Meanwhile, the group is working on a new specification, HomePlug AV, which will focus on moving video around a home and offer 200-Mbps rates. That specification is complete, and chip samples that support HomePlug AV are due late this year."

Code may be taking a back seat for now,
but the pioneering spirit that put the code
there in the first place is out front of it all.
