How to build a real PTT experience

Why PTT still wins for critical ops

In industrial and response teams, simultaneous talk creates chaos. Push-to-talk enforces one speaker at a time, improving focus and reducing mistakes.

Queueing with emergency priority

NoSim uses a speaking queue and SOS priority so critical messages jump the line. This keeps large rooms disciplined and predictable.

Implementation checklist

• Keep press-and-hold timing consistent and short.
• Show clear "your turn" and "in queue" signals.
• Cap concurrent speakers at one.
• Add an emergency key for urgent broadcasts.

UX impact

When queues and signals are correct, users feel the real radio experience and conversations remain smooth and trusted.
