New Super Faster Internet Connections With Existing Cable TV Networks

The demand for high-speed Internet access is expected to increase significantly with the growing availability of video on demand, teleworking and easier access to government services. However widths banda existing soon be inadequate as a single TV programme converted to digital domain requires about 5 megabits per second (MB / s). The Eureka (Belgium) project has resulted in super-fast Internet connections over existing cable television networks without the need for a consumer modem.

Existing services banda ancha cable TV are based on data over Cable Service Interface Specification (DOCSIS). This requires a cable network upgraded to support two-way interactive data processing together with a cable modem active in the final consumer, which can, at best, only provide connectivity asymmetrical.

Project coordinator @ Home, former Essent Kabelcom, the cable television provider for much of the Netherlands, worked closely with two of its suppliers to develop the necessary technology. "We have a longstanding relationship with both Teleste in Finland and Tratec Telecom in the Netherlands and ideas, so the idea of them," explains Jelle Cnossen of @ Home.

Speeds may be higher delivered over telephone lines using 56 MB / s-VDSL technology, but this is limited to short distances from exchanges. The project VIRTUAL fiber set to boost Internet speeds over existing copper-based coaxial TV cable connections at home. The resulting technology offers speeds of up to 10 times that possible with existing cable TV Internet connection. It also offers Ethernet local area network (LAN) connectivity without requiring a consumer-side modem; users need only connect their personal computers (PCs) in a standard connector on the wall. And there is no active ingredient, the Ethernet connection is free from interruptions.

A pilot project in the Dutch town of Boxmeer demonstrated the success of the Ethernet-to-the-home (EttH). Now, all 28000 local residents have symmetrical access to the Internet 10 MB / s, with local companies able to obtain 50 MB / s symmetrical data connectivity. The technology has been developed to provide 100 MB / s connectivity and has already been sold to South Korea, reflecting the global market for that approach.

"This was the first time they had participated in a project of Eureka," explains Esko Myllyla of Teleste, the Finnish project responsible for much of the technical work. "Eureka labelling is not absolutely necessary for us but was important in the eyes of our local public funding authorities. Moreover, the Eureka label helped pull the three parties in this project together more strongly - that is the key benefit . Everyone realized that we were not developing things each on our own behalf, but were developing something together. "
