Commentary: Use DRM on India’s FM Band

All India Radio (AIR) has adopted the Digital Radio Mondiale (DRM) standard for digital terrestrial radio broadcasting in MW and SW bands. Thirty-eight high-power DRM transmitters are carrying regular digital transmissions, either in pure digital and/or in simulcast mode.

Sometime back, AIR had issued instructions to increase the transmission hours of such transmitters in pure digital mode. Also each of the four metro cities had been asked to operate one transmitter in Pure Digital Mode. Over 80% of the Indian population was expected to be able to receive radio programs in digital. And this is before most of these transmitters started operating in pure DRM digital mode.

India is currently carrying out trials of ITU-approved standards, including DRM, in the FM band. DRM is fully compatible with the existing FM band transmissions. It utilizes the unused white spaces in the spectrum, technically unavailable for further analog FM expansion.
