Communication

The Cellocator™ Handsfree device enables fleet management assistance representatives to listen to a driver of a vehicle, as well as to what is happening inside the vehicular cabin during times of distress, after the panic button has been activated.

Additionally, the unit can serve as a voice communication device between the driver and the control representative, eliminating the need for a hand-held mobile phone.

The Cellocator™ Handsfree allows for full duplex voice connectivity via microphone and speaker. The driver may initiate, answer and disconnect calls via a service button, or alternatively, by pressing the panic button. There is also an auto answer mode, which enables the call to get through without driver involvement – which serves as a useful tool in times of distress or as a safety measure. The destination of the call is programmed with a predefined number (i.e. the service center). The Cellocator™ Handsfree unit also supports silent monitoring, in which the caller can listen to the driver and what happens in the cabin but the speaker is muted.

The unit controls the transmission of the voice from the car to the GSM network and vice versa. The unit also controls the voice characteristics like ringer volume, speaker volume and microphone gain. The unit also is responsible for echo canceling, a must for full duplex operation.
