General Information
MOTOTRBO is a Motorola digital radio product marketed primarily to business/industrial users. The format is based on, and compatible with the European 2-slot DMR standard and uses Time Division Multiple Access (TDMA) to effectively accommodate two simultaneous users. A single 12.5 kHz channel is able to carry two simultaneous and independent conversations, or simultaneous and independent voice and data paths each with 6.25 kHz equivalency, however the bandwidth of DMR exceedes the maximum required for UHF 6.25 kHz channel centers. Operation of different talkgroups and talkpaths similar to trunking is possible, as is wide-area operation through IP connectivity. MOTOTRBO transceivers and repeater stations may be retrocompatible with analog FM using CTCSS or CDCSS.
No scanner can monitor this digital format by itself but it can be monitored with DSD. Other decoding efforts have been started, such as Ian Wraith's DMRDecode. DMRDecode is unable to decode audio.
Emission designators for MOTOTRBO: 7K60FXE (voice), 7K60FXD (data).
MOTOTRBO is based on the following ETSI standards:
- ETSI TS 102 361-1 Air interface
- ETSI TS 102 361-2 Voice and generic services and facilities
- ETSI TS 102 361-3 Data protocol
Additional information on DMR is available through the Digital Mobile Radio Association.
