wireless frequencies

Available frequency space for wireless microphones

The use of a wireless microphone mainly takes place in the UHF broadcasting band.
The frequency ranges in this band in which use is permitted are listed below.


Licenses the Netherlands

In the Netherlands you can use the following frequencies without a license:

THE NETHERLANDS
Frequency Max.
195-202 MHz 50 mW e.r.p.
470-556 MHz 50 mW e.r.p.
558-564 MHz
50 mW e.r.p.
566-572 MHz 50 mW e.r.p.
574-580 MHz 50 mW e.r.p.
582-588 MHz 50 mW e.r.p.
590-596 MHz 50 mW e.r.p.
598-604 MHz 50 mW e.r.p.
614-694 MHz 50 mW e.r.p.
823 - 826 MHz 20 mW e.i.r.p. (handheld)
100 mW e.i.r.p. (bodypack)
826 - 832 MHz 100 mW e.i.r.p.
863-865 MHz 10 mW e.r.p.
European free band
1785-1805 MHz 20 mW e.i.r.p. (handheld)
100 mW e.i.r.p. (bodypack)
1G8
1880-1905 MHz 1G9
2400-2483 MHz 2,4 GHz, WiFi

However, you cannot fully use the 470 - 694 MHz band in the Netherlands everywhere.
You share that space with digital broadcasting. The use of frequencies for
Digital broadcasting differs per region. This also increases the availability of frequencies
regionally different for wireless microphones. If you want to know which frequencies
you can use it at a specific location within the Netherlands, then you can use the
application Microphonetapes from the Telecom Agency.

Licenses Belgium

In Belgium you can use the following frequencies without a license:

BELGIUM
Frequency Max.
518-526 MHz 50 mW e.r.p. Channel 27
534-542 MHz 50 mW e.r.p. Channel 29
863-865 MHz
10 mW e.r.p. ISM
1795-1800 MHz 20 mW e.i.r.p. (handheld)
100 mW e.i.r.p. (bodypack)
1G8

You need to apply for a license for the other frequencies.
You can do this at the Belgian Institute for Postal Services and Telecommunications.
Here you can also download a list of the permitted frequencies per region.

Licenses Germany

In Germany you can use the following frequencies without a license:

GERMANY
Frequency Max.
174-216 VHF
174-230 MHz 50 mW e.r.p.
470-280 MHz Kanäle 21-37
614-703 MHz Kanäle 39-49
733-758 MHz Kanäle 54-56
788-791 MHz Kanal 60
823-832 MHz 100 mW e.r.p. Kanal 65
863-865 MHz 10 mW e.r.p. ISM
1785-1805 MHz 82 mW e.i.r.p.
1795-1800 MHz 20 mW e.r.p. 1G8
1880-1905 MHz 1G9
2400-2483 MHz 2,4 GHz, WiFi

You can also use the 470 - 694 MHz band, but then you first have to use one
apply for a license by downloading a form from the Bundesnetzagentur .
You can apply for a permit for a specific location and it is valid for a maximum of 30 days.

License-free frequencies

There are a number of frequency bands that can be used throughout Europe or even around the world without a license. To begin with, there is the so-called band gap or duplex gap (823-832 MHz). This is actually a kind of buffer between the uplink and the downlink frequencies of mobile providers. It's a very narrow piece so you can't use many systems side by side in this band. There is also an increased risk of intermodulation in this band if there are many mobile phones in the area. The same also applies to the 863 - 865 MHz band. This band is just above the frequency range that is reserved for mobile providers and, like the 823-832 MHz band, can be used in virtually all of Europe without a license.

Systems that operate on the 2.4 GHz band (2400 - 2483.5 MHz) have the great advantage that they can operate globally without license. However, this is also the disadvantage because this band is therefore very popular and is used by the most diverse devices. Microwaves, WiFi, Bluetooth ... they all use the 2.4 GHz band. Many of the consumer devices have recently moved to the 5GHz band, so hopefully it will become a bit quieter in the 2.4GHz band in the near future. Another disadvantage is that this band has a very short wavelength. The shorter the wavelength, the smaller the range is. Under ideal circumstances you should be able to reach a meter or 30, but the range will not be much larger. In practice you can use a maximum of 6 wireless microphones or in-ear systems next to each other in the 2.4 GHz band.

Developments

Due to new developments in mobile technology, the frequency landscape is constantly changing. In practice it means that there is less and less room for wireless audio. At the beginning of 2016, the 800 MHz area throughout Europe was taken into use by mobile telephone providers. Microphones in that frequency range no longer work. Of course this was announced well in advance. From January 1, 2020, you can no longer use frequencies in the 700 MHz band between 694 and 790 MHz for wireless microphones due to the introduction of 5G.
