Nautel Supports DRM+ Test in India

Technologies demonstrated at Air India test also shown at Singapore convention

Nautel said its VS-1 low-power FM transmitter was a key component in DRM+ trial measurements in India.

The test, organized by All India Radio and the Digital Radio Mondiale Consortium, demonstrated the viability of the DRM digital radio technology in the FM band for the Indian market, according to participants.

DRM+ is designed to operate in the VHF bands, having been tested in Bands I and III as well as VHF Band II, traditional home of FM radio.

AIR and the DRM Consortium also used an RFmondial DRM+ modulator and Fraunhofer DRM content server during the tests, part of a week-long DRM+ showcase in New Delhi in May. The test frequency of 100.1 MHz carried three program channels while testers measured DRM+ reception in a vehicle moving in four different directions from the Nautel transmitter. 

Nautel provided a 300-watt (500 W radiated power) VS-1 low-power FM transmitter.

Nautel and the DRM Consortium showed a similar system at the Broadcast Asia conference in Singapore this week.
