Wireless Microphones & The Law: Is Your House of Worship Using Illegal Frequencies?

In today’s environments, clear, reliable audio is essential. Wireless microphones are a core part of that—freeing up movement for pastors, worship leaders, presenters, and performers alike. But if your system is operating on the wrong frequencies, you could be violating federal law without even knowing it.
The Problem: FCC Frequency Reallocation
Over the past several years, the Federal Communications Commission (FCC) has reallocated portions of the UHF spectrum—previously used by wireless microphones—for commercial wireless services like 5G. Most notably, the 600 MHz band (614–698 MHz) was auctioned off, and using this range without a proper license is now illegal.
If your microphones operate in these restricted frequencies, you risk interference, fines, or even system shutdowns.

How to Know if You’re at Risk
Ask yourself:
Did we purchase our wireless microphones before 2017?
Do we know what frequency band they operate on?
Have we experienced recent interference or signal drops?
If you answered yes or I’m not sure, it's time to check.
What You Can Do
Audit Your Current System
Look up the frequency range on your wireless mic receivers or transmitters. It’s usually printed on the back or under the battery cover.
Avoid These Frequencies:
614–698 MHz has been illegal since 2013.
700 MHz (698–806 MHz) has been illegal since 2010
Choose Legal Bands
Stick to safer zones like:
470–608 MHz (still available for wireless mic use)
902–928 MHz
1.9 GHz (DECT systems)
2.4 GHz (Wi-Fi-based systems)
Consider Upgrading
Modern systems are more efficient, reliable, and compliant. Bonus: many new models can auto-scan and avoid interference.
