The utilisation of designated radio frequencies
Use of radio frequencies defined by general authorisation is laid down in individual general authorisations. The terms and conditions under which the relevant frequencies and frequency bands can be used are set out in these general authorisations. Here is information about certain groups of equipment we are frequently asked about:
Short Range Devices
Frequencies and the terms and conditions of their utilisation are presented in General Authorisation No. VO-R/10/07.2021-8 for the use of radio frequencies and for the operation of short range devices.Here is the overview of some of the most frequently asked frequencies for these devices:
| 27 MHz | Operation is possible according to VO-R/10/07.2021-8. |
| 49 MHz | Operation is not permitted (devices interfere with radio service and non-civil applications). |
| 230–400 MHz | The band is reserved for the purposes of national defence – no civil operation is permitted. |
| 433 MHz |
Operation is possible according to VO-R/10/07.2021-8. (only data transmission; wireless headsets are not permitted) |
|
470−694 MHz, 823–832 MHz |
The operation of wireless microphones is possible according to VO-R/10/07.2021-8. |
|
694–823 MHz, 832–862 MHz |
The operation of wireless microphones is no longer permitted. |
| 863–865 MHz | The operation of acoustic applications is possible according to VO-R/10/07.2021-8. |
|
863–876 MHz, |
Operation is possible according to VO-R/10/07.2021-8 |
|
694-823 MHz, 832–862 MHz, 876-915 MHz, |
Band for the operation of mobile networks – the operation of other applications is not permitted. |
| 1,2 GHz | Cannot be used in Europe for short range devices. |
| 1785−1800 MHz | Operation of wireless microphones is possible according to VO-R/10/07.2021-8. |
| 2,4 GHz | Operation (RLAN, RFID, short range devices) is possible according to VO-R/12/11.2021-11 nebo VO-R/10/07.2021-8. |
Equipment in the 2.4 GHz and 5 GHz band
The 2400–2483.5 MHz band is currently the one that is used very intensively. Based on general authorisations VO-R/12/11.2021-11 and VO-R/10/07.2021-8 this band is shared by wireless network applications, including wireless Internet (RLAN, WLAN - IEEE 802.11b, g, n standards), Bluetooth equipment and certain other applications (wireless cameras, railway applications, RFID, etc.). The state control of electronic communications deals quite often with problems caused in particular by non-compliance with the established performance and, pursuant to Electronic Communications Act, sanctions them.
In the 5 GHz band, operation is possible according to VO-R/12/11.2021-11 and VO-R/10/07.2021-8 in the 5.15-5.35 GHz band (the use outside the building only in the 5.15-5.25 GHz band is subject to registration), in the 5.470-5.725 GHz band, in the 5.725-5.850 GHz band (subject to registration) and, under certain conditions, now also in the 5.945-6.425 GHz band.
Notes for RLAN /(WLAN) equipment operation:
- The producer/distributor of the equipment is obliged to indicate in the instructions for use (which must be attached to each equipment in Czech language) the conditions under which the eqipment may be operated in the Czech Republic in accordance with General Authorization No. VO-R/12/11.2021-11. In particular, the producer/distributor must indicate what type or type of antenna may be used on the equipment in order for the equipment to meet the conditions under which conformity has been assessed. Based on this information, the operator of the radio equipment is required by the producer to comply with a broadcasting scheme that complies with the above General Authorisation. In general, when using a directional antenna (if the producer/distributor allows this type of antenna), the operator must reduce the power of the equipment so that the radiated power is in accordance with the general authorisation.
-
As the General Authorisation shows, the stations are operated on shared frequencies. The operation of the station does not provide protection against interference caused by transmitting radio stations of another radiocommunication service operating under an individual authorisation for the use of radio frequencies or by other stations for broadband spread spectrum or OFDM data transmission. Any interference shall be resolved by mutual agreement between natural and legal persons.
If they fail to agree, the procedure shall be in accordance with Section 100 of the Electronic Communications Act, or the user who put the interfering station into operation later shall cease operation.
BMIS equipment
The operation of wireless local information system (BMIS) stations in the 70 MHz band is possible according to General Authorisation No. VO-R/2/05.2018-5.
Broadband data transmission stations incl. point-to-point links
The use of radio frequencies and the operation of equipment in the 10 GHz frequency band is possible according to General Authorisation No. VO-R/14/05.2020-7.
The use of radio frequencies and the operation of equipment in the 57-71 GHz frequency band is possible according to General Authorisation No. VO-R/12/12.2019-10.
The obligation to report is laid down in relation to the bands 5,2 GHz, 5,8 GHz, 57–66 GHz and 71–76 / 81–86 GHz. Further information about the web reporting portals is provided in relevant general authorisations.
