Harris Helps out Dublin DAB Trials

DB Digital Broadcasting to double DAB services, expand coverage

DB Digital Broadcasting is using Harris high- and low-power Platinum VAX VHF air-cooled transmitters and PowerSmart technologies in its DAB digital radio trials.

The trial is broadcasting three services in the Dublin area — All 80s, UCB, and Raidió Rí-Rá, with each service using the traditional DAB and new DAB+ standard. The DAB+ service includes displays images as well as the audio broadcasts.

All 80s is working with All-In-Media’s Rapid software to deliver updated information from “now playing” to weather and traffic information, as well as listener requests delivered via Harris DAB transmitters.

The DAB transmitters are configured differently from Irish national broadcaster RTÉ’s analog MUX, said Harris, to allow direct comparisons of both services. The differences in distance and building penetration between systems will be investigated to help with planning the single frequency network aspect of the trial.

“We selected Harris as our transmission partner since the company has an exceedingly good track record stretching over many years and is a recognized world leader in DAB technology,” said Dusty Rhodes, managing director of DB Digital Broadcasting. “Harris’ involvement in projects such as Norkring’s creation of the world’s largest DAB radio network in Norway will enable it to manufacture DAB transmission solutions on a far greater scale and create economies of scale. The company’s transmission track record, married with its direct experience in DAB radio, makes Harris an attractive proposition for us.”

By Christmas, DB Digital Broadcasting plans to double the current DAB radio services offered on the Dublin network, and in 2013 it plans to expand coverage to Cork and Limerick.
