This page compares DAB+ and DRM+ and highlights the key differences between them based on various parameters.
Introduction:
DAB (Digital Audio Broadcasting) and DRM (Digital Radio Mondiale) are both digital audio broadcasting technologies. DAB+ and DRM+ represent upgraded versions of DAB and DRM respectively, offering improvements in performance and features.
The following table provides a detailed comparison between the two standards:
| Parameters | DAB+ | DRM+ |
|---|---|---|
| Frequency | 174 to 240 MHz (Band III) | 47 MHz to 68MHz 87.5 MHz to 108 MHz 174 MHz to 230 MHz |
| Programs per channel | 9 to 24 (Typically), 64 (Max.) | 1 to 4 (Max.) |
| Channel Bandwidth | 1.5 MHz | 96 KHz |
| Modulation | Multi carrier (1536) OFDM, DQPSK type modulation over -768KHz to +768KHz | Multi carrier (106) OFDM, 4 to 16 QAM modulation over -48KHz to +48KHz |
| Digital data speed (Kbits/sec) | 2400 | 120 |
| Input of transmitter | Digital ETI 2.048 Mbps or EDI (ETI over IP) | Multiplex Data Interface (MDI) 37 to 186 kbps |
