1      Introduction.

The communication platform SiteraPtt adds the already proven advantages of the communication world between radio terminals as the use of PTT (Push To Talk) and the group calls.

PTT allows having the microphone muted when you are not talking, useful in noisy environments and especially in group calls, this allows you to hear who is talking without the background noise of the other participants. PTT also removes the necessity of waiting to the establishing of the call from the caller and the necessity of answering from the called one done.The audio starts reproducing to the recipients the moment the button is pressed.

The group calls allows to spread the audio between all the parcipants simultaneously,without the need to do a conference call.

To this radio communications benefits joins the ones that the mobile telephony has , such as the wide coverage or the internet access.
