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[edit]
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[edit]
dPMR446 radios are licence-free products for use in the 446.1–446.2 MHzMegaHertz (MHz) 10^6 Hz band within Europe.
