Push-to-talk communication (PTT) is the core attribute of Motorola iDEN handsets.  PTT enables users to instantly connect and share data via direct communication.  This immediate connectivity can help companies increase productivity, realize efficiencies and minimize costs by improving workforce coordination and enabling rapid decision-making. Some of the PTT features are that it allows managers to set up call groups and connect with up to 100 people at a time, in case of emergency or during times of crisis, provides point-to-point communications between devices for up to seven miles when no network coverage is available, including underground, and can withstand dust, shock, vibration, extreme temps, solar radiation and rain via military-spec materials and design, according to the manufacturer.
