DGT MUŁKMobile Critical Communication Device


The Mobile Critical Communications Device is designed to provide critical group communication of PTT type.

It is available in two varieties: transportable (installed in vehicles) and portable (to be carried in a backpack). DGT MUŁK allows (via the Radio over IP gateway) to connect many devices using different systems and different networks, and the implemented software ensures efficient, effective and fully automatic transfer of the transmission channel between them so that it is possible to connect to the IP infrastructure. It is intended to connect in all conditions with VOIP or PBX telephone systems, dispatcher communication systems (e.g. DGT MCS) or DGT PTT Connect smartphone application.


The following can be connected to DGT MUŁK:

  • digital radio (handheld or mobile) of any manufacturer (Motorola, Hytera, Kenwood, Excera etc.), working in any of the available systems (e.g. TETRA, DMR, NXDN and P25),
  • analogue radio of any manufacturer,
  • two independent GSM cellular networks (2G, 3G, 4G LTE and 5G),
  • WiFi devices
  • satellite telephone,
  • additional modems working on dedicated frequencies.

DGT MUŁK is equipped with a GPS system module, enabling position transfer to map systems. By default, the device is set to radio. Its disappearance causes automatic switching to another type of transmission. You can manually select an available means of communication at any time.

DGT MUŁK allows communication and cooperation of groups located in various locations (in the country and abroad). It is enough for one of the members of each group to be equipped with this device.
