Does using a wireless remote control in Türkiye require a licence or frequency assignment?
No; for short range devices inside the exemption no frequency assignment and no radio licence are sought. The condition is meeting the technical annex.
No. For short range devices within the scope of the exemption no frequency is assigned and no radio licence is required. The framework in force in Türkiye is the “Regulation on Radio Equipment and Systems Exempt from Frequency Assignment” (Frekans Tahsisinden Muaf Telsiz Cihaz ve Sistemleri Hakkında Yönetmelik), dated 27 November 2018. The exemption is not unconditional: in terms of band, power and duty cycle the device has to comply with the annex of technical criteria to the regulation.
The scope and the conditions of the exemption
This regulation replaced the previously effective Short Range Devices (SRD) Regulation and the Private Radio Systems Regulation. For devices within its scope:
- No frequency assignment is made.
- No radio licence or usage fee is required.
- In return, the device is obliged to comply with the band, maximum power, bandwidth and duty cycle limits defined in the regulation's annex of technical criteria.
These criteria are largely aligned with CEPT's ERC/REC 70-03 recommendation, but do not attribute the numbers in the European tables directly to Türkiye; what is binding is the Turkish regulator BTK's own annex of technical criteria. Industrial remote controls commonly use the 433 MHz, 868 MHz and 2.4 GHz bands; which band you work in also decides which row the limits are read from. If you want the exact values of the limits, look at the annex of the relevant legislation itself; do not trust tables passed on at second hand.
Who carries the responsibility? Declaring that the device meets the conditions of the exemption is the job of the manufacturer or of whoever places it on the market; what falls to the user is to use the device in the state in which it was declared. In practice this distinction settles here: the band, the output power and the duty cycle are fixed by the design and are not in your hands; the antenna, the mounting and the supply conditions, on the other hand, are in your hands, and changing them can invalidate the declaration.
The exemption gives no protection
The exemption also gives no protection. You work in an unlicensed band; if another device transmitting in the same band disturbs you, that is not a breach of the regulations and it is not resolved by complaint. The resilience of the system against interference has to come from the design. The practical consequence is this: on crowded sites a frequency hopping set drops out less than a fixed single-channel set; the duty cycle limit, meanwhile, is the real constraint on the design in remote controls that send commands continuously, and it has to be thought about before range.
What to check when buying and when installing
| Check | What to look for | If it is missing |
|---|---|---|
| Declaration of conformity | The number and version of the standard applied | Conformity is not assumed |
| CE marking | On the product and on the packaging | Placing on the market is problematic |
| Operating band | The band declared in the manual | The scope of the exemption is unclear |
| Antenna | The antenna and connector supplied by the manufacturer | The declaration can become invalid |
| Manual | Installation and pairing procedure | An acceptance test cannot be made |
Where the exemption falls away
Changing the module yourself, enlarging the antenna, adding an external amplifier or raising the output power invalidates the exemption; from that point on the device is no longer the product the manufacturer declared, and the responsibility passes to you. The same holds for cutting the antenna short — and it usually lowers the range as well. Exemption from a licence does not cover machinery legislation either: adding a wireless remote control to an existing machine can give rise to a separate assessment.
In short, do not chase a licence, chase documents. Ask for the declaration of conformity of the set when you buy it and keep it in the machine file, note the operating band down from the manual, and do not touch the hardware. A business that takes these three steps holds the answer to the question that is asked both in an inspection and in the field.
