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
- An app on the smartphone (or a rugged device) is the talk button.
- Voice travels over the cellular network or Wi-Fi to the cloud and reaches recipients in real time.
- 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.
