| GSM Range – Technology | ||||||
Ultra-reliable digital transmission Daitem GSM transmitters do not use the voice channel to transmit data. Indeed, when this channel is used the signal is sent via the GSM compression and decompression networks and is therefore deformed and distorted. This means that if there are any echoes on the network or the reception is bad, transmission of the signal is not guaranteed. However, because Daitem GSM transmitters use the indication channel and transmit the signal in entirely digital mode, according to the Daitem Dual-Tone Multi-Frequency (DTMF) protocol, both the level and quality of the message are perfectly controlled. |
||||||
| Personalised voice messages Daitem GSM transmitters are highly flexible making it easy to use the system in voice mode. All identification, alarm and acknowledgement messages can be personalised using multilingual voice synthesis. What’s more, this can apply to 8 inputs! |
