Short Answer
In Switzerland, radio frequencies cannot be used arbitrarily. BAKOM's National Frequency Allocation Plan assigns frequency ranges to various radio services. For simple applications, there are unlicensed or non-concession areas like PMR446 or CB radio under clear technical conditions. Professional operational radio, security radio, mobile radio, aviation radio, radio microphones, radar, amateur radio, and military uses each follow their own rules. It is important for companies: Before procurement and programming, allowed use, concessions, frequency allocation, and channel planning must be clarified.
Many search inquiries ask for a single frequency. However, in practice, it is not only the number that matters but also the allowed application, the device, the power, the location, and the responsibility.
Important Radio Areas in Practice
| Area | Typical Classification | Important |
|---|---|---|
| VHF | Various professional, public, and technical radio services. | Use only according to allocation and specifications. |
| UHF | Operational radio, security radio, PMR446, object radio, and further applications. | Widely used, not freely selectable. |
| 27 MHz | CB radio. | Not requiring a concession under defined conditions. |
| 446 MHz | PMR446. | Only compatible devices and technical limits. |
| Mobile Communication | 2G/4G/5G, operator frequencies, private networks. | Concessions and operator concepts must be observed. |
Who uses 400 MHz?
The area around 400 MHz belongs to the UHF environment and is used for different radio services. Publicly known is, among others, the connection of POLYCOM or security radio to the area around 380 to 400 MHz. Nearby, there are also other applications, such as PMR446 at 446 MHz. This does not imply that any device may transmit there.
What is a forbidden frequency?
There is no universal single "forbidden frequency" for all cases. Use is forbidden when the device, frequency, power, application, or location do not comply with the specifications. Frequencies for security radio, aviation radio, mobile radio, radar, authorities, military, or other protected services are particularly critical.
FAQ
Which radio frequencies does the Swiss police use?
Police and other emergency organizations use regulated security communication. Specific operational frequencies and permissions are not to be understood as freely usable information for personal applications.
On which frequency may I transmit without a license?
Typical examples are PMR446 and CB radio, but only with suitable devices and under the respective technical conditions.
What mobile frequencies are there in Switzerland?
Mobile frequencies are allocated to operators and used technologically neutral for 2G, 4G, 5G, or future services. For current details, BAKOM and ComCom are authoritative.
On which frequency do airplanes operate?
Aviation radio is a distinct protected radio service. For companies outside aviation, no free use can be derived from it.
Which frequency does the Bundeswehr or military use?
Military frequency usage is not relevant for normal operational radio projects and should not be interpreted as freely usable area.
What is the best frequency for radio microphones?
This depends on the device, location, event, interference, and current regulation. For professional events, frequency use on-site should be checked.
