PTT is the "PoC" (PTT) mobile phones, integrated cell phone and walkie-talkie function, it uses the cell phone network. PTT walkie-talkie phone and generally different from one radio without the network, and second, and general radio only a short distance, compared to the call by power transmission, this business has a strong advantage, including roam.

Its features are:
1. Can quickly carry out "one to one" or "one to many" call, the same as using the intercom call machine.
2. Have to wait after dialing the phone compared to the "one key" in 3 seconds after pressing the call button can be turned around, speak to one second delay is also within close professional walkie-talkie.
3. And the only close-talk walkie-talkie different PTT service can be accessible to mobile phone networks can cover the place, almost no distance limitations.
4. And radio rely on high investment compared to private network, mobile phone intercom can make full use of CDMA network operators to significantly reduce operating costs and the user cost.

Push to Talk (PTT) feature is a new mobile Technology, Can quickly be "one to one" or "one to many" call, the same as using the intercom call machine. This feature requires frequent contact for small and medium-sized enterprises and the need to chat with friends and family members of individuals. However, this function must use the built-in cell phones, regular phones can not use the PTT function.

After the opening of PTT mobile phones, just click the corresponding button on the phone, you can use your cell phone and was selected group to achieve "one to one" or "one to many" calls. U.S. CDMA operator Nextel's PTT service, need to hold down the button on the main machine can only speak, but let go, the other party hear the "tick" bang, before the speech. Close call with the radio only different PTT service can be accessible to mobile phone networks can cover the place, almost no distance limitations. The PTT service can be in accordance with the duration, time and traffic to billing, can also be monthly, depending on the operator. High-pass and Nextel CDMA operators in the U.S. commercial precedent term, a monthly system costs 15-30 dollars.

The PTT freely roaming, remote call, easy to use and low cost advantages, the increased communication between operators and reduce the cost of revenue is "PTT" key selling point. However, the "Push to talk," there is still some shortcomings. Technically speaking, POC and no matter how high technical threshold. In fact, reaction time and other technical indicators, this mobile phone technology to achieve the cluster-to-talk communication technology cannot contend with the cluster.

"PTT" is a welcome technology, but new technology will inevitably be inadequate. According to some people who have had experience with introduction, "PTT" call during the delay problem still exists. Moreover, because "one key" approach by sending packets, the delay is even larger than the radio, generally within a few seconds delay in, the resulting transmission of voice people feel uncomfortable process. Of course, some companies can delay control called within one second, but in large-scale network transmission process, their true effectiveness, but also practice.
