dPMR is an open, non-proprietary trunked radio standard developed by ETSIEuropean Telecommunications Standards Institute. An independent, not-for-profit, standardization organization in the telecommunications industry in Europe, developing global telecommunications standards., published under ETSIEuropean Telecommunications Standards Institute. An independent, not-for-profit, standardization organization in the telecommunications industry in Europe, developing global telecommunications standards. TS 102 658. Supports both data and digital voice transmission.
Characteristics
dPMR uses FDMAFrequency Division Multiple Access of 6.25 kHzKiloHertz (kHz) 10^3 Hz bandwidth with a raw data rate of 4800 bpsBits per second (bps) (user data rate: 3600 bpsBits per second (bps)). dPMR uses 4FSK4-Level Frequency Shift Keying at 2400 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.. The dibits are mapped to +/-1050 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). and +/-350 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). from the center frequency.
Because the emission mask is so tight, two 6.25 kHzKiloHertz (kHz) 10^3 Hz dPMR signals can be used next to each other within a 12.5 kHzKiloHertz (kHz) 10^3 Hz channel without causing interference to each other or adjacent channels
Frequencies
dPMR446 radios are licence-free products for use in the 446.1–446.2 MHzMegaHertz (MHz) 10^6 Hz band within Europe.
