PTT (Push To Talk) - definition

A two-way correspondence administration which works like a "walkie-talkie".

PTT is half-duplex so correspondence must be moved toward each path in turn as opposed to cell phone calls which are full-duplex and the two players can hear one another.

PTT requires the individual addressing press a specific button while talking and to deliver it when they are done so the audience can reply by rehashing similar advances. In this manner individuals control which one can talk and be heard and the framework knows in which course the data ought to be moved.

Most PTT frameworks permit bunch calls (one individual addresses every one of the individuals from the gathering).

The freshest PTT frameworks use VoIP innovation and the sign is moved over the 2.5G or 3G organization.
