Hydro-power monitoring - DMR link
Alexandre Van Damme
The following set-up unlocks your digital radio network to transfer metering data via VHF/UHF at no additional infrastructure cost.
A Mototrbo data channel is a low speed data pipe with an efficient over air data transfer rate of 1200 bps. It is suitable for transmission of simple telemetry reporting such as (level-meter values, GPS location coordinates or alarms & messages). The datathroughput of a Mototrbo radio channel will vary based on the channel configuration, eg simplex, data revert, or trunking. The data messages are 322 bytes including a 16-byte mototrbo header. A message takes approximately 2.14 seconds to transmit. For this very reason, Mototrbo telemetry applications use a 3-second updating cycle.
