Club DAB Italia Rolls Out National SFN DAB Network with wcom Technology

Italian network operator Club DAB Italia has rolled out the countrys nationwide DAB service with help from 2wcoms FlexNsert and FlexXtract . In a technical first for Italy, the 2wcom technology was deployed to allow the DAB network to be fed with an ETI stream and distributed over a large geographical area.

Before using satellite distribution Club Italia relied only on a limited network of radio links, which would not have been adequate for the speedy development of a national DAB network. To provide a better distribution infrastructure, the company installed technology from 2wcom including FlexNsert encoders providing the ETI to ASI conversion, and FlexXtract receivers with ETI and EDI output.

Fabrizio Guidi, Club DAB Italias President, commented: The system delivered by 2wcom made it possible for us to have a rapid and successful roll-out of our national network one of the largest SFN DAB networks in Europe, currently covering over 3000 km of highways and major roads in Italy, and reaching more than 50% of the population.

The FlexNsert DAB Distribution Inserter receives a DAB ETI data stream (according to EN 300799) or a DAB EDI data stream (according to TS 102 693). The FlexNsert DAB converts the data stream into a standard MPEG2-TS-signal and outputs it via its transport stream interfaces. Additionally the FlexNsert may act as timestamp inserter for SFN Networks. The generation of timestamps within the MPEG-stream is basis for a synchronized transmission at transmitter sites. The FlexXtract DAB Distribution Extractor demodulates a data stream (2048 kbps) from a DVB-S or DVB-S2 signal and converts the data into a standard ETI-signal according to (EN 300799) or EDI-signal according to (TS 102 693) to feed DAB or DAB transmitters.

We chose the 2wcom system because it allowed us to build a simple, reliable and cost-effective distribution chain for a fast-growing network, said Hanns Wolter, technical manager for the project. Although this was a technical first, implementation proved to be extremely fast and we were up and running within days of delivery. Over time we have been able to appreciate the reliability of the units and the excellent customer support from 2wcom.
