Evidence of stations according to VO-R
Web portal to keep record of stations in 5,2 GHz, 5,8 GHz and 60 GHz band
The web portal (https://rlan.ctu.gov.cz/en) is used to submit notifications on the use of radio frequencies by fixed outdoor installations in bands 5,2 GHz, 5,8 GHz and 60 GHz, given by the General Authorisation No. VO-R/12/11.2021-11 for the use radio frequencies and for the operation of equipment for broadband data transmission in the bands 2.4 GHz–71 GHz.
The reason for introducing the registration of stations in band 5,2 GHz is the protection from interfering with other radiocommunication stations. The protection is based especially on keeping the records of the overall number of these stations operated in the Czech Republic in outer environment, in order to ensure that the total effect of radiation is not exceeded. The conditions of protection are summarized in the ITU Resolution 229.
Band 5,8 GHz or some of its sub-bands are, or could be, used by military radars and additional electronic road toll systems. Therefore, CTU decided to define static geographic circular areas with prohibition to operate stations (protective areas) and remove these from the possibility of mutual coexistence of individual applications utilizing the same or adjacent frequencies. Therefore, the condition of notification on the Office’s Portal applies to the outside stations. The notification does not apply to stations with integrated antenna where their producer indicated maximal e.i.r.p. up to 200 mW. At the same time, CTU can define temporary protective areas depending on the use of primary radiocommunication services (especially radiolocation).
In the 60 GHz band, for the promotion of lower probability of mutual interference, the web portal has several functions which will allow the providers of broadband data transmission stations to optimize mutual sharing. One of these functions is so-called coordination calculator, which serves as an indicative tool to look up suitable conditions for mutual compatibility and sharing.
To make the calculation and indication of potential mutual interference (to optimize mutual sharing) possible, it is necessary to notify technical specification of the stations when notifying thereof. The range of required data is defined in a relevant part of the General Authorisation VO-R/12.
Using defined range of registered (notified) data, in this case so called MAC Wireless address of the station, CTU targets on the need to ensure an easier identification of stations by the control bodies of the Office in cases where the local investigation is in process, e.g. in relation to appearance of harmful interference. In such cases, the remote identification of properly notified stations decreases the administrative burden on entities operating stations in the given area and other entities in relation to requests to provide data by other persons, e.g. property owners or end-users. As a result, the notification condition increases the effectivity of Office’s control activities without putting unnecessary burden on undertakings and citizens.
You have to submit the notification for use of radio frequencies before you actually start to use them, however, not earlier than 5 business days ahead. To submit the notification, you need to register to the portal.
Web portal to keep record of P-P links in 71–76 GHz and 81–86 GHz
With effect from 1 August 2024, the obligation to notify stations in the frequency bands 71-76 GHz and 81-86 GHz is abolished, i.e. from this date onwards, station operators are no longer obliged to notify via the portal vor-kmitocty.ctu.cz. After this date, the portal will continue to operate for an unspecified period of time. The possibility of notifying the stations concerned is thus not limited, but it should be noted that, in view of the abolition of the notification obligation, it cannot be guaranteed that the scope of the notified fixed radio links is complete after this date.
To submit the notification, you need to fill in given electronic form (ZFO) and submit it via web portal ESD II. Submitted form can be re-downloaded from the web portal ESD II and amended (e.g. to finish filling in the form).
You can also make amendments to already submitted form. After amending submitted form, you need to re-submit it via ESD II web portal .
The given form is available only after you sign in to the ESD II web portal. To sign in, you need to register, i.e. you need to have log in details - login name and password (user account). You will receive these details after successful registration in the ESD ii web portal.
