Japan ponders powerline networks
2005-01-09
THREE Japanese electronics giants are preparing to establish standards for using domestic electricity wiring for high-speed network services. Panasonic brand maker Matsushita, Sony and Mitsubishi Electric issued a joint statement announcing that they were creating an alliance to set up global standards to allow appliances built by different companies would interconnect. Under the technology, data would be transmitted not via telephone lines but by power lines - theoretically providing powerful internet access in any room that is wired for electricity. And in contrast to telephone lines, power lines would allow computers to run on the same network as appliances such as televisions, refrigerators and heating thermostats, opening new possibilities for secure, remote access. Powerline communication "is considered a critical bi-directional communication channel that will support home networking in the future," the companies said. The technology has been made available in recent years in limited trials in the United States, Europe, Australia and parts of East Asia. Japan, however, has not yet allowed it as it weighs concerns that the technology could interfere with ship and aircraft radio communications.

#7  Data transmission over electric power lines causes interference to communications in the high frequency spectrum. This is the region where most international emergency communications take place. BPL effects those trying to hear them. It is a bad idea.

Installing and maitaining cable is cheaper. RF broadband at UHF and above is also availible. BPL is bad news. As some one who uses HF com links daily I know just how much this will damage my ability to hear the person trying to talk to me. I already suffer from encroachment from man made unintentional interference, BPL is intentional interference as powerlines are just huge antennas. Nothing that the Power company can do will stop the signal genereated by BPL fron radiating into the enviroment. This is just greed and stupidity.

BPL can never compete with fiber, cable or phoneline on cost or bandwidth. It won't be used to get broadband to the rual markets it will be used in built up metro areas where their is a faint hope that money can be made from it. It costs a ton of money to deploy and maintain, it's destructive to the HF radio environment and is going to be a nightmare. This is one rathole we don't need to toss money down.

#5  While big cities have cable and DSL broadband, many smaller communities have no broadband offerings. (No local cable TV service and phone DSL is distance limited.)

As someone who grew up in a very small community (<500) I'll have to disagree. This might have been true 10-20 years ago but, in the US at least, this bit of common knowledge is rapidly becoming erroneous.

For example, my hometown has had cable television for almost 20 years and cable internet access for a couple of years. There's also a local provider who utilizes microwave links to provide high speed internet access to rural customers. Also, the local telephone exchange owner (an individual) is beginning a project this summer to pull fiber optic cable to every home (rural & in town) in his service area to provide integrated digital cable, telephone, & high speed internet access. Then there's DirecTV's high-speed offering that's available everywhere in the continental US.

This community is a small isolated town in the middle of nowhere in the midwest, far from any major (or even minor) city. If that many access options are available there it's safe to assume that the buildout is continuing apace and will reach most everyone in relatively short order.

#4  â€œThe primary reason they are doing this is to save their antiquated, but still very profitable, infrastructure of centralized energy production.”

Electronic technology continues to improve and get much cheaper. Power transmission systems already require communications for monitoring and control. As power systems are better conditioned they also make better communications networks. If a power company can use power lines for communication their operational expenses and cost go down. Once the technology is available to the power companies, it is natural that the power companies would want to offer broadband to their customers.

While big cities have cable and DSL broadband, many smaller communities have no broadband offerings. (No local cable TV service and phone DSL is distance limited.)

TV, stereo, computer, and appliance makers want to add new capabilities without adding complexity. Devices that when plugged into wall socket would automatically detect and communicate with other home devices would improve the customer value. The devices could also relay diagnostic data to a repair center. (Manufacturers are adding wireless communications in a similar manner.)

Electrical transmission systems will still be needed even when more distributed power systems are available. Indeed, the power transmission system will have to be better conditioned to handle local power fluctuations as small power generators come on/off line. Power management will continue to be a high tech, profitable business.

(I’m all in favor of fuel cells, modern nuclear plants, and distributed power generation. I also agree that too many of our power generation and transmission facilities are antiquated. The companies that aren’t antiquated are the ones installing new equipment that will allow new service offerings such as powerline bandwidth.)

#2  The primary reason they are doing this is to save their antiquated, but still very profitable, infrastructure of centralized energy production. Now that fuel cell technology is exploding, and to a lesser extent very small and safe nuclear reactors (pioneered in Japan and South Africa), they see that high-tension electricity transfer is in decline.

#1  Please give the BPL a rest. I get enough interference to radio communications from leaky transformers right now. Adding BPL noise will not help. This is a form of data transfer that we can do without.
