Radiotelefony dPMR

The dPMR (digital Private Mobile Radio) standard is a digital professional radio communications standard that, unlike DMR (TDMA), uses FDMA (Frequency Division Multiple Access) technology in a very narrow 6.25 kHz channel. This standard is promoted by companies such as Icom and Kenwood, with the very popular dPMR446 variant available for license-free use.

dPMR Radios – Digital Quality in a Narrow Channel (FDMA)

dPMR (digital Private Mobile Radio) radios are a modern digital communications standard based on efficient FDMA (Frequency Division Multiple Access) technology. Using very narrow 6.25 kHz channels, dPMR provides crystal clear voice quality, increased interference immunity, and better coverage than traditional analog, especially at the signal edge.

The dPMR system is flexible and scalable, encompassing both unlicensed dPMR446 devices and advanced trunking systems (Mode 2 and Mode 3) on licensed bands.

Why Choose dPMR?

• Better Edge Coverage: Narrowband FDMA technology (6.25 kHz) provides lower background noise, resulting in clearer and more reliable voice at the edge of coverage, where analog FM fails.
• Spectral Efficiency: The dPMR standard is highly efficient – ​​it allows for twice as many channels (32) in the unlicensed 446 MHz band (dPMR446) as the standard Analog (16 PMR446).
• Easy Migration (Dual Mode): Most dPMR radios offer the ability to operate in both analog (PMR/FM) and digital modes, allowing for a gradual transition to digital while maintaining compatibility with your existing fleet.
• Professional Features: The dPMR system supports advanced enterprise features such as individual/group calls, remote monitor, digital scrambler (encryption), and short message and GPS data transmission (in licensed modes).
• Choose dPMR radios for simple yet professional license-free digital communications (dPMR446) or for scalable, digital conventional and trunked networks in your company.
