Frequencies for wireless microphones - Introduction

Frequency allocations for radio applications and broadcast for wireless microphones and cameras in Germany.

Radio applications for the transmission of sound and images for programme creation and Events are known internationally as "Programme Making and Special Events" (PMSE).
Radio microphones are used for one-way wireless transmission of speech, music or sound signals and are used, for example, in programme productions, at music events, Theatre performances, in churches, in congress or training rooms or in the private sector.

For events as well as for radio and stage productions, the following can be used as required stage directions, command signals or the live sound into an ear worn small receivers are transmitted (in-ear monitoring). The receivers of radio microphones are also used in cameras or worn on the body. Radio microphone transmitters can also be used in musical instruments.

Radio microphones do not enjoy any protection against interference by equal users. The various operators must therefore coordinate the use of radio microphones with each other on site.

The Federal Network Agency as the regulating authority for radio frequency transmitters approved in Germany provides the following general allocations of frequencies for PMSE, programme production and special events (this describes all wireless production equipment used in any form in the professional production of events and content) in accordance with the following specification.

32.475 - 34.325 MHz and 36.610 - 38.125 MHz

PMSE wireless audio equipment is radio equipment designed to transmit analogue and digital audio signals between a limited number of transmitting and receiving devices, such as radio microphones, in-ear monitoring systems or audio links, used primarily for the production of radio programmes or at private or public social or cultural events.

863 - 865 MHz

PMSE wireless audio equipment is radio equipment for the transmission of analogue and digital audio signals between a limited number of transmitters and receivers, such as radio microphones, in-ear monitoring systems or audio links, which is mainly used for the production of radio programmes or at private or public social or cultural events.

For individual allocations, radio microphones are allocated frequencies from the following frequency ranges:

- 34.25 MHz - 38.05 MHz

Users: public service broadcasters, private broadcasters
and producers, service providers of event technology, everyone for hobby purposes,
Congress centres, museums, theatres etc.

- 470 MHz - 608 MHz, 614 - 694 MHz and 733 - 823 MHz

Users: 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 production equipment. This includes programme productions as well as other professional events and facilities, such as theatre performances, concerts by professional music groups or professional services of event technology. 

The subranges 758 to 788 MHz and 791 to 821 MHz, which are also used for downlink transmissions of wireless network access, form an optional additional capacity for the use of radio microphones. Operating frequencies from these subranges may only be used by the frequency assignment holders in compliance with the other provisions if no other operating frequencies can be used at the respective operating location for technical or operational reasons within the scope of the assignment.

- 1350 MHz - 1400 MHz

Users: public service broadcasters, private broadcasters
and producers and other professional users of wireless production technology.
The 1350-1400 MHz frequency range can be used after approval by the military Consumer for use by radio microphones within closed buildings for be allocated a defined area of operations.

The operating frequencies will be allocated by the frequency assignment holder from the Frequency assignment of the specified frequency range. Frequency uses of radio microphones must not interfere with applications primary radio services cause and enjoy no protection against interference through applications of primary radio services. Cause frequency use by Radio microphones Interference in applications of primary radio services, is the interfering
to immediately terminate the use of frequencies by radio microphones.

- 1452 MHz - 1518 MHz

Users: public service broadcasters, private broadcasters and producers and other professional users of wireless production technology.
- Frequencies in the 1492 to 1518 MHz subrange may only be used within
buildings are permitted. The 1452 to 1492 MHz subrange, which is also used for downlink transmissions of wireless network access, forms an optional additional capacity for the use of radio microphones. Operating frequencies from this sub-range may be used by the frequency assignment holders in compliance with the other regulations, can only be used if the respective operating site is technically not or for operational reasons, no other operating frequencies within the allocation are usable.

These frequencies must be coordinated independently by the network users and shared with other network operators (DVBT). The use of these frequencies varies from state to state. The following table:

The manufacturers of wireless production equipment have reacted to the scarcity of the frequency spectrum with different technologies.
