What Is Push to Talk and Do You Need It?

Push to talk is an important feature of two-way radios and other communications equipment. Also called "press to transmit", it enables the operator to start communications with another individual or with his or her team at the push of a button.radiolandingicon-1.png

The term has its origin in the early history of two-way radio communication, where the PTT button physically engaged the operating mechanism of the handheld two-way radio transmitter.

Why Certain Industries Use Push to Talk

Historically, push to talk has often been the norm in fields such as public safety, security, construction, transportation, and manufacturing. Reasons for its popularity in these contexts include:

  • It is easy to activate, allowing the operator to focus on the job at hand
  • It enables quick, efficient communication confined to a predefined group of people who need to hear the whole conversation

As a feature of two-way radios, PTT has offered some advantages over cell phones in certain industries:

  • Security is improved because open cell phone networks, which can be vulnerable to security risks, are avoided when two-way radio frequencies are used
  • Clarity is improved because both the technology itself and PTT protocol require communicators to take turns and communicate clearly
  • Instant connectivity at the press of a button, whereas cell phone features are designed more for versatility and convenience
  • Durability and safety, devices with PTT as part of their physical design are meant to withstand the stresses of hazardous and demanding situations

Having instant access to communicate to your network is the main reason why PTT enabled devices have been a mainstay in environments where coordinating teams in a time-critical manner is crucial. Even as the cell phones have become ubiquitous over the past decade or so, in many industries and fields, PTT on a two-way radio has remained the best form of communication.

Push to Talk in the Digital Era

PTT functionality has been added to a range of digital devices including cell phones. As mobile carriers offer push-to-talk services on the devices they support, PTT functionality is available on smartphones and specialized mobile handsets. Some services also function on a laptop, desktop, or tablet computer. Where such devices are appropriate and convenient, push-to-talk can offer the operational advantages of PTT while incorporating the advantages of a range of mobile devices.

Since digital radios are becoming the industry norm, PTT capability basically means instant access to the digital network that you are working on. If a business or institution is using a dispatch-enabled network, every device that has access to it through push to talk will be able to communicate through it. This means that two-way radios, cell phones, and even computers (with the appropriate application installed) are capable of accessing the network with the push of a button.

This gives you the ability to use the strengths of two-way radio communication, such as coordinating large work groups, through mobile devices. Using a digital network, users aren't limited only to voice only. They can also make use of features such as GPS tracking, instant messages, and data transmission, just like they would on a smartphone.
