Public Mobile Radio Trunking Service (PMRTS) is an instant, two-way mobile (radio) communication service that allows a group of people to communicate with each other, even if some or all of them are on the move. Sometimes it is also known as Push-to-talk (PTT), also known as Press-to-Transmit, a momentary button to switch from voice reception mode to transmit mode. Push-to-talk calls are half-duplex communications — while one person transmits, the other(s) receive. A typical Push to Talk connection connects almost instantly. One significant advantage of PTT is that it allows a single person to reach an active talk group with a single button press; users no longer need to make several calls to coordinate with a group.

PTT is best suited for demands for quick communication among end-users. Due to the fact that PTT is provided in half-duplex mode (e.g. transmission occurs in both directions, but not at the same time – each party must wait to speak), the inability to interrupt lends itself to quick exchanges of information, as is the case with the market for business users that need to quickly exchange information and then get along with their business.

With a significant world-wide emphasis on Public Safety and Homeland Security, PTT will increasingly become important for government, public safety personnel and other officials as a communications tool (among other tools such as Wireless Emergency Service, Priority Service, etc.), serving the need for efficient communications during times of emergency, disaster, or threats.
