Voice communication is possible also. Then usually an additional GSM/UMTS modem will be integrated into the vehicle including driver microphone, loudspeaker and interface to the vehicle computer system to manage these voice calls. Herewith voice calls from the dispatcher to the vehicle and reverse are possible.
As alternative to the GSM standard we offer as well VoIP solutions, if UMTS or LTE is well available.
Emergency calls for example to the dispatcher, to the police or any other organisation is possible also. Furthermore it is possible to attach a hidden attack button to the vehicle to trigger these emergency calls.
If desired other communication systems like DMR or Tetra can be intergrated as well.
