5 Things To Know About New Regulations For Wireless Mics

by | Alec Olson

You might not be in the audio industry, but every industry uses audio solutions and that means upcoming FCC changes to the bandwidth available for wireless microphones can impact everyone.

Wireless microphones transmit sound to speakers, amplifiers and recording devices without a cable connection. Their uses include broadcast media, music venues, corporate events, and more. Wireless microphones can include hand-held or body-worn styles, including in-ear monitors.

Regulations are difficult to keep track of in the best of times, but when changes are being made it becomes even harder. Here are some likely questions about the FCC’s changing regulations, as well as answers that will keep your service compliant and uninterrupted.

If you’d like to chat about your wireless band compliance or rebate opportunities, reach out to speak with an expert here.

What You Need To Know About FCC Regulation Changes

Question: What regulation is changing?

Answer: The FCC allows wireless microphones to operate on both a licensed and unlicensed basis. Most wireless microphones use spectrum in the TV band. However, starting in 2017, the FCC has been limiting the amount of spectrum available to wireless microphone users.

In particular, almost all of the spectrum in the 600 MHz band has been repurposed. Wireless microphones operating at the frequency must cease operation by July 31, 2020. In addition, wireless microphones are prohibited from operating in the 700 MHz band, which is reserved for public service entities such as police, fire and emergency services, as well as for some commercial wireless broadband service providers.

Question: Why is the regulation changing?

Answer: The FCC has repurposed spectrum in the 600 MHz band for use by wireless services, including bandwidth for smartphones. Wireless microphones in the 600 MHz band that interfere with these new licenses may be required to cease operation in that band sooner than the 2020 deadline.

Many frequencies continue to be available to wireless microphone solutions, including VHF and UHF frequencies on TV channels 2-36, which fall below 608 MHz; certain frequencies in the 600 MHz guard band, or 614-616 MHz; and, certain frequencies in the 600 MHz duplex gap, or 653-657 MHz for licensed use and 657-663 MHz for unlicensed use.

Question: What audio solutions will be impacted?

Answer: Wireless microphones and wireless devices similar to wireless mics, including in-ear monitors, audio instrument links and cueing equipment will be affected by the new bandwidth regulations. Antenna connections and power sources will also be impacted. According to the FCC, the best way to determine whether your current wireless microphone system will be impacted is to contact the manufacturer to determine what frequency is being used.

Question: Why does compliance matter?

Answer: Compliance is especially important if you are considering a purchase of a new wireless microphone system or upgrading a current system. If you are purchasing a new system now, be sure it meets the new regulations, not the ones currently being phased out. Failure to comply could also result in fines or criminal penalties.

Question: Where can you go for help?

Answer: System manufacturers or a qualified service provider can help you determine what frequency your current wireless microphone system is using. Users in the 700 MHz band can also request assistance and information from the FCC’s Consumer Center.

Certified AV integrators can help you choose and deploy a new wireless microphone system and/or evaluate the state of your current system.

What Can You Do Today?

Although the deadline for leaving the 600 MHz band is several years away, any wireless microphone systems interfering with new wireless broadband licensees in the same bandwidth can be forced to cease operations with as little as 120 days’ notice.

Rather than scrambling to find and deploy a new wireless microphone system, take steps today to determine whether your system will meet new compliance standards and, if not, what you need to do to be compliant before the deadline.

Acting now can also save you money. Many of AVI's partner manufacturers including Shure, AudioTechnica and Sennheiser are offering rebates to users who trade in an old system and purchase a new, compliant one.
