Short Answer
PoC broadly refers to Push-to-Talk over Cellular via mobile networks or IP networks. MCPTT is Mission Critical Push-to-Talk according to MCX standards and focuses on prioritized, robust, and integrable operational communication. PoC may suffice for normal operational processes; for security-critical organizations, priority, availability, emergency calls, group management, interoperability, and operational concepts are crucial.
Both terms are often mixed up. The distinction is important for procurement and operation.
Comparison
| Criterion | PoC | MCPTT |
|---|---|---|
| Objective | Commercial group communication. | Mission-critical Push-to-Talk. |
| Priority | Limited depending on the platform. | Conceptually central. |
| Integration | Often app- and platform-oriented. | Part of MCX/3GPP architectures. |
| Application | Operation, logistics, service. | Critical communication and hybrid networks. |
Decision Criteria
- How critical is the communication failure?
- Are there requirements for priority and emergency calls?
- Does a control center need to be integrated?
- What networks and devices are available?
- How is blackout or fallback communication resolved?
Typical Errors
A normal PTT app is understood as a mission-critical solution without demonstrating availability, priority, emergency call, and operational obligations.
FAQ
Is MCPTT better than PoC?
MCPTT is designed for higher requirements. For simple operational processes, PoC may be sufficient.
Does MCPTT require 5G?
Not necessarily only 5G; MCX can be viewed through suitable LTE/5G architectures.
Can PoC be combined with radio?
Yes, hybrid solutions can connect radio, PoC, dispatchers, and mobile radio.
When should one consider MCPTT?
When communication is security-critical and priority, emergency calls, control center, or resilience are important.
