bisa engga yaa hal di bawah ini diterapkan di indonesia lewat jaringan pln ???? fadill -------------------------------------------------------------- http://www.dawn.com/2001/03/25/int9.htm Internet via electricity connection HANOVER, March 24: Cutting-edge companies hailed the commercial premiere of Web access and phone services via electric wall sockets - power lines - at Germany's giant Cebit computer and telecommunications fair on Saturday. But industry representatives at the event in the northern city of Hanover remained sceptical that so-called power line communications could beat the links offered by phone lines or TV cables. Its proponents say power line can offer data transmission, Internet access and phone services to homes or offices via electrical power grids, and at lower prices and higher speed than anything else on the market. The technology has been a developer's dream for decades but had never gone beyond field trials. Germany's largest utility, RWE, and Swiss equipment maker Ascom told reporters at Cebit they would now make power line a reality with the launch the first commercial service in July in Germany's western Ruhr region. Called PowerNet, the service promises a maximum data transmission rate up to 30 times faster than ISDN digital phone lines. RWE Plus chairman Manfred Remmel said that speed would allow users to download a song from the Internet in about 17 seconds, compared to the longer than real-time rates generally seen today. "We are bringing the Internet back to what it should be: a fast medium that offers people the chance to communicate and exchange information cheaply," he said. The technology works with adapters that change data signals into frequencies electricity networks can carry. Modems at the socket then separate data from electricity. Users will be able to use electricity and power line communications simultaneously and maintain a constant Internet connection. The cheapest PowerNet service is priced at 49 marks (22 dollars, 24 euros), limited to 250 megabytes of data transmission or the equivalent of 2,500 e-mails, RWE developer Michael Rogall told AFP. RWE hopes to win 20,000 customers for the service by the end of the year, providing the first commercial test of a technology has its roots in the 1940s. Ascom said it was aiming for quick expansion throughout Europe, southeast Asia and South America. Although the news generated a buzz at the fair, power line already has its share of detractors, the most prominent of which is Germany's Siemens. Three days before the start of the fair Thursday, Siemens announced it would abandon its own power line communications projects indefinitely, saying it did not see the potential to win a mass market in the foreseeable future. The company cited potential technical problems such as noise on the power line created by interference from other appliances which could lead to disruptions in service. Long distances between customers and their electricity sub-stations and differing technology standards from country to country could also lead to unreliable service, it said. Possibly more problematic were the regulatory hurdles facing such projects, which must undergo an arduous approval process before telecommunications authorities, Siemens added. RWE argued that they expected the final obstacle to approval of power line communications to be cleared at the end of March, when the German upper house of parliament is expected to pass a bill governing transmission frequencies. The technology Ascom uses in its modem had already won the blessing of Germany's telecommunications watchdog, RegTP, it added. Other companies meanwhile are still banking on power line including Germany's third largest utility, EnBW and Israel's Main.Net, both of whom are developing pilot services for German regions.-AFP -- Sent through GMX FreeMail - http://www.gmx.net ---------- Piksi-L @ somewhere.in.the.world merupakan 'mailing-list' alumni asisten Piksi, ITB, Indonesia.
