The global push-to-talk (PTT) market was valued US$ 21,382.4 million in 2017 and is projected to reach US$ 55.011.3 million by 2027; it is expected to grow at a CAGR of 11.2% during 2020-2027. PTT is an instant one-to-one or one-to-group mobile voice communication method that works on half-duplex communication; it does not involve protracted dialing, ringing, and answering steps as that of a regular phone call. PTT allows one person to speak at a time and facilitates floor communication. Advancements in PTT systems and services enable them to exhibit enhanced capabilities. High efficiency of mobile voice communication, which is not available in any other communication tool, is the key benefit of these devices. The PTT devices are mostly used in air traffic telecom systems, police radios, cellular systems, etc. The government, public safety, manufacturing, and construction sectors, among others, are the key adopters of these devices.
