Short Answer
PMR446 is license-free short-range radio with limited power, fixed conditions, and shared channels. This can suffice for small teams and simple deployments. In companies with safety processes, buildings, repeaters, many groups, high availability or sensitive communication, licensed operational radio is often more suitable.
PMR446 is attractive because it appears simple and inexpensive. However, for professional processes, it must be verified whether the limits are acceptable.
Typical PMR446 Limits
- Limited transmission power and range.
- Shared channels without exclusivity.
- Interference from other users possible.
- Limited system functions compared to operational radio.
- No freely plannable repeater infrastructure like in operational radio.
PMR446 or Operational Radio?
| Criterion | PMR446 | Operational Radio |
|---|---|---|
| Entry | Simple and quick. | Planning and frequency clarification needed. |
| Coverage | Limited. | Plannable with repeaters/building radio. |
| Channels | Shared. | Plannable according to organization. |
| Safety Processes | Only limitedly suitable. | Significantly better controllable. |
Typical Errors
PMR446 is used for critical operational processes without considering range tests, backup devices, battery management, or interference risk.
FAQ
Is PMR446 Allowed for Companies?
For simple applications, PMR446 can be used if the devices and usage comply with the regulations.
When is PMR446 Insufficient?
In large buildings, critical processes, many groups, repeaters, safety services or high availability.
Is PMR446 Secure from Eavesdropping?
No. Channels are shared and simple eavesdropping must be taken into account.
When is Operational Radio Better?
When communication must be plannable, reliable, extendable, and organization-specific.
