What is PTToC (Push-to-Talk over Cellular)? Meaning and how it works

PTToC stands for Push-to-Talk over Cellular — “press to talk” over the mobile network. It is a form of instant, half-duplex voice communication (one person talks at a time): you press a button, talk, and the message reaches a colleague or a group right away, using the mobile internet (3G/4G/5G) or Wi-Fi instead of radio waves.

PTT and PTToC: what is the difference?

  • PTT (Push-to-Talk) is the concept: voice communication by pressing a button, like a walkie talkie.
  • PTToC (PTT over Cellular) is PTT that travels over the cellular/Wi-Fi network instead of radio. It is the “walkie talkie” that works anywhere there is signal.

How PTToC works

  1. An app on the smartphone (or a rugged device) is the talk button.
  2. Voice travels over the cellular network or Wi-Fi to the cloud and reaches recipients in real time.
  3. A portal lets the control center manage channels, see the team on a map and review history.

What PTToC is for

Instant communication for field teams: security, logistics, industry, retail, healthcare and events. It replaces the traditional radio with more range, messaging, location and management. Compare in detail in our Push-to-Talk for business guide.
