Frequency availability
Frequency availability (including frequency sharing , English frequency supportability, frequency clearance ) is the written, official and legally binding approval of the competent national sovereignty carrier for spectrum matters whether the possibility for that wireless application, radio station or radio system to participate in the proposed radio service exists and whether in this respect at least a radio frequency or frequency channel is available. In Germany, frequency availability can only be granted for the part of the electromagnetic spectrum (including radio frequency spectrum) from 9 kHz to 275 GHz that is regulated and allocated in accordance with the Radio Regulations .
assignment
The European NATO countries usually have a National Radio Frequency Agency (NARFA) to examine, process and explain or reject frequency availabilities. In some NATO countries, such as Greece, this mandate is carried out by the civil authority responsible for frequency matters.
For the armed forces of the Bundeswehr and the organizational area of the BMVg , this mandate is fulfilled in BITS by NARFA DEU. NARFA DEU coordinates with the relevant neighbors for cross-border applications, such as in the mobile radio service .
Determinations in Germany
Legal stipulations
As early as the State Secretary decree from 1956, it is mandatory to clarify the frequency availability before initiating the procurement process for military equipment that is to use radio frequencies on German territory and for which protection against electromagnetic interference is sought.
The approval of the Federal Network Agency (BNetzA) is mandatory for frequency ranges that may be used exclusively for civil purposes or jointly for civil / military purposes in accordance with the Frequency Range Allocation Ordinance or the frequency range allocation plan.
For devices with so-called safety of live services , such as the air navigation radio service , the Federal Ministry of Transport (BMV) must also be involved.
If necessary, detailed specifications and decisions are made on the basis of EMC investigations , studies, simulations and field tests.
Application and notification
The application for frequency availability must be made in writing. The frequency availability notification is also made in writing and can be made nationally, internationally, with conditions, restrictions and time-limited, but also negative. NARFA-Germany as well as BNetzA and BMV are independent in their decisions.
A positively determined frequency availability regularly loses its validity if one of the conditions, such as an increase in the transmission power, has been changed.
Civil radio stations, the use of which is permitted in Germany according to the decision of the Federal Network Agency, but which are to be used or operated by the Bundeswehr or the guest armed forces, such as radio transmitters ( broadcasting service ) or instrument land systems ( air navigation service ), do not require a military frequency availability declaration, but a civil allocation of the required frequencies or frequency channels. Here, too, NARFA-Germany provides support.
International frequency availability was granted for cross-border military radio applications such as JTIDS or Have Quick , but with national restrictions.
Guest Forces
The use of radio stations of the visiting armed forces generally requires approval by the German radio frequency administration in the exercise of its function as host nation. For military equipment, the frequency availability may be granted by NARFA-Germany. The NJFA provides important guidance for the guest armed forces concerned . Civil radio applications are the responsibility of the BNetzA, but NARFA-Germany can provide support.
Frequency allocation
The allocation of a radio frequency or a frequency channel to a military user or operator of a radio application usually only takes place on the basis of a positive frequency availability.
Users or operators of civil radio stations, radio systems or radio systems receive a frequency assignment or frequency channel assignment, provided that the necessary requirements are met, which is usually part of a frequency assignment certificate from the Federal Network Agency . Radio stations that have a general operating permit from the Federal Network Agency, such as DECT cordless telephones or wireless microphones, do not require a frequency allocation.
