General broadcasting of non-public land mobile radio microphones (wireless microphones)
Wireless microphones are used for one-way wireless transmission of voice, music, or sound signals and come z. For example, in program productions, at music events, theatrical performances, in churches, in Congress or training rooms or the private sector.
For events and radio and stage productions, stage directions, command signals or live sound can be transmitted to a small receiver worn on the ear as required (in-ear monitoring). The receivers of wireless microphones are also used in cameras or worn on the body. Wireless microphone transmitters can also be used in musical instruments.
How to find the two-way radio frequency
Wireless microphones enjoy no protection against interference by equal users. The various operators must coordinate the use of wireless microphones locally.
For the operation of wireless microphones, general allocations have been issued for several frequency ranges. For individual assignments, frequencies for radio microphones are assigned from the following frequency ranges:
- 470 MHz – 608 MHz, 614 – 703 MHz
(registration and fee-based, for professional installations and touring sound)
- 470 MHz – 608 MHz, 614 – 703 MHz
(registration and fee-based, for professional installations and touring sound)
Consumer: Public service broadcasters, private broadcasters, and producers, as well as professional users of wireless production technology. Professional wireless production is the commercial and expert use of wireless means of production. These include program productions as well as other professional events and facilities, such as theater performances, concerts by professional music groups, or professional event technology services.
- 703 – 733 MHz
If no allocations are granted (from 2018 LTE area)
- 733 – 823 MHz
(registration and fee-based, only conditional and location-specific allocations)
The sections 758 to 788 MHz and 791 to 821 MHz, which are also used for downlink transmissions of the wireless network access, form an optional additional capacity for the use of wireless microphones. Operating frequencies from these sub-areas may only be used by the frequency assignment holders in compliance with the other provisions if, for technical or operational reasons, no other operating frequencies can be used within the scope of the allocation at the respective operating location.
- 823 – 832 MHz
(registration and free of charge, use only for wireless microphones)
PMSE wireless audio equipment is radio equipment for transmitting analog and digital audio signals between a limited number of transceivers, such as wireless microphones, in-ear monitoring systems, or audio links, used primarily for the production of broadcast programs or private or public social or cultural events be used. The max. Transmission power may be 100 mW. Wireless PMSE Audio Equipment 823-832 MHz (PDF, 25 kByte) (Vfg. 02/2015)
- 863 – 865 MHz
(registration and free of charge no guarantee for freedom from interference.)
The above frequency range is also used for other radio applications. The Federal Network Agency assumes no responsibility for a minimum quality or freedom from interference in radio communications. There is no protection against interference by other intended frequency uses. In particular, the mutual use of frequencies cannot be ruled out and accepted. Microphones in the frequency range 863 – 865 MHz (PDF, 38 kByte) (Vfg. 47/2013)
- 2400 – 2483,50 MHz
(registration-free and free of charge no guarantee for freedom from interference.)
This frequency range is assigned to the general public, among other things for use by radio applications of short-range. This includes wireless microphones with the corresponding technical parameters. Short Range Devices (SRD) (PDF, 62 kByte) (Vfg. 30/2014 modified with 36/2014 and 69/2014)
Information of the highest telecommunication authority Austria
- 470 – 790 MHz
(secondary operation by wireless microphones)
In the frequency range 470 – 790 MHz, the situation for wireless microphones remains unchanged. However, no frequency gaps are available between the TV channels. On the other hand, in the GE06 plan, there are regionally limited, unused channels (“white spaces”) between the large-scale TV plan entries that can be used by wireless microphones. The corresponding FSB-LT009 radio interface is published on the bmvit website Whereas the conversion to digital terrestrial television may limit the spectrum of frequencies available to radio microphones in some areas, in particular in the area of national borders, through the cross-border use of DVB-T The TV stations currently operating and planned are on the RTR GmbH published.
- 790 – 862 MHz
(Future Mobile Radio Area)
The 790-862 MHz frequency range will no longer be available for wireless microphones in the future. Due to the use of mobile radio secondary use of this frequency range by wireless microphones in the future is no longer possible. Having regard to the Commission Decision of 6 May 2010 laying down harmonized technical conditions for the use of the 790-862 MHz frequency band for terrestrial systems capable of providing electronic communications services in the European Union and Council Decision No 67/52 of 14 July 2010 In Austria, the “Digital Dividend” will be awarded in the course of 2011 / beginning of 2012. In the duplex frequency range of the 791 – 821 MHz and 832 – 862 MHz mobile radio, wireless microphones will only be authorized for a limited period until the end of 2011. Federal Ministry of Transport.
- 823 – 832 MHz
(exclusive use by professional wireless microphones)
The duplex gap in mobile communications from 823 – 832 MHz will in future be available exclusively for wireless microphone applications under the same technical conditions as in the frequency range 470 – 790 MHz. These developments are also reflected in the last amendment to the Frequency Usage Ordinance of 24 February 2011, Federal Law Gazette II No. 068/2011.
- 863 – 865 MHz is a Europe-wide harmonized frequency range. The corresponding radio interface Sub-Class 46 is published on the ECC website.
