Wireless Mic Freqs for Germany and Denmark

(1/2) > >>

TomBoisseau:
I need to construct a very small "rack" for a client of mine which will consist of a telephone hybrid and a wireless mic.  This system will be used here in the United States and also in  Germany and Denmark.

Can anyone tell me, or tell me how to find, what "group" of frequencies are legal in these countries?  I will most likely specify  the Sennheiser G3 100 series wireless.

Also, any problems using an "American" telephone hybrid in these countries?

Thanks so much,
Tom

I can only speak for Denmark.

Here it's been 800-820 MHz for many years, but like many other places we're being moved around now to allow for 4G cell-network and digital broadcast signals.

So the current situation for Denmark is that 823-832 MHz has been opened and will stay open for unlicensed use. Same goes for 863-865 MHz.

800-820 MHz is still open and will remain so until December 31st 2012. Then (from the start of 2013 that is) 800-820 MHz will be closed for our use.

From this time on (start 2013) we will also be using the white spaces in the range 470-790 MHz (I think - something like that). I don't know if this area is already open - might be. There will be maps online showing the white spaces available wherever you may be or you can scan the spectrum for them.

Will there be both outbound program audio, and inbound remote audio on the telephone, or will the phone line be listen only for the remote users? If it is going to be listen only you may be better off with something like the JK Audio THAT-2 which interfaces to the telephone handset, so it doesn't matter whether the phone line is POTS, PBX, or ISDN.

It may also be easier and safer to rent the wireless mic in each country. The same rules will not necessarily apply in all countries. In most of Europe RF frequencies have to be paid for to the licensing authority, and they will assign what frequency you can use. With a lot of preplanning you can probably find frequency sets that will work in a lot of places, but renting locally means the local vendor will take care of the licensing for you.

Depending on what you need from the phone line, bringing a hybrid or a handset adapter may work out, but it will be better to rent RF locally.

In Germany you can use 790 - 814 and 838 - 862 MHz without a license until 2015.
Be advised that mobile interent carrieres (LTE) are beginning to operate on 790 - 820 and 832 - 862 MHz, first in rural areas, later in the cities also. So there may be intereferences. The carriers try to co-operate, so basically only one carrier has to build a network in one area and the other 2 carriers use that network. For us it means that only 10MHz of bandwidth are being used.

Under 790:

You can get a license for 710 - 790 MHz, per tour or gig, possibly for the whole country. Not sure about how far they are with country-wide licensing.

Under 710:

It is possible to get gig licenses between 470 and 710 MHz.

If you have questions about licensing, just ask.

TomBoisseau:
Thanks for the help guys.  It looks like I'll need to purchase 2 wireless systems - 1 to use in the US and another for Germany/Denmark.

Thanks again,
Tom
