Wireless Microphone Frequencies

August 9, 2018 by Art Vivas

Have you seen the movie 2020 yet? There was the 1984 movie where the world was going to end. Then there was 2012. Though each of these epic entertainment films ended with a bright full future, the 2020 concept is the same, and 2020 too can end up with a bright future.

No, there is no 2020 movie yet. Well, as far as we know there isn’t, but there is a significant impact that will occur in 2020 or by 2020. As least for those in the AV world and yours too if you own a wireless microphone system.

The 600 MHz change

According to the FCC, wireless microphones operating on 617-652MHz or 663-698MHz are to cease operation no later than July 23rd, 2020.


Also, did you know that wireless microphone systems are already banned from being used specifically on the frequencies between 698 and 806MHz?

The Issues You Face

There are two group of wireless microphone systems recognized by the FCC. Licensed and Unlicensed. Licensed operators are those who have permission by the FCC to operate within the 600MHz band.

These operators can include broadcast networks, cable television operators, AM, FM stations, and large venue owners/operators and professional sound companies that will 50 or more wireless mics for their events.

The unlicensed operator is where most of us wireless microphone operators live, which is in the low 600MHz or the high 500MHz range.

Other frequencies to consider that are permitted by the FCC (for unlicensed wireless microphones) are 902-928MHz and 1920-1930MHz. Depending on the power levels of your wireless microphones, portions of the 2.4 GHz and 5 GHz bands are also available.

Now the situation becomes this: understanding that you may need an upgrade to your wireless microphone system, you will want to consider the basics of how many transmitters you will need, the addition of an antenna booster, mute features and battery operation (rechargeable or disposal).

Wireless System Use

Taking care of these first steps will grant you a quality signal within the correct bandwidth. A signal that can be crucial to your ministry.

Think of your signal usage and how your wireless microphone systems are used. This could be for a livestream over the internet, archive recording of your service, podcasts, concerts, bands, guest speakers, weddings, large functions and holiday events.

It’s quite a bit. And with each event, you want a reliable system that functions without any technical difficulty.
