FAQs for Unlicensed LPAD (Including Wireless Microphone) Registrations

Universal Licensing System - Help

This article provides a list of frequently asked questions (FAQs) related to unlicensed low power auxiliary device (LPAD) registration which includes unlicensed wireless microphones. The registration process for these devices provides interference protection from TV white space devices. Large venues that cannot accommodate all of their unlicensed LPADs including wireless microphones on channels that have been set aside for LPAD use can register for protection on additional channels.

How do I determine the reserved channels at my location?

The database administrators provide tools that identify white space channels for a particular location. If you select “Wireless Microphones” as the type of device when using the tool, it will list channels that are available for wireless microphone use. The reserved channels are annotated as “Reserved” or “Exclusive” in the results.

How do I determine the other available TV channels at my location?

The database administrators provide tools that identify white space channels for a particular location. If you select “Wireless Microphones” as the type of device when using the tool, it will list channels that are available for wireless microphone use. Other available TV channels are channels in the range of 14-51 that are annotated as “Available”. You are not required to use VHF channels (Channels 2-13) that are listed as "Available".

Why do I need to register my wireless microphone?

Most people do not need to register their wireless microphones or other unlicensed low power auxiliary devices. The FCC has set aside channels that can be used by these devices without interference from TV white space devices. These are the reserved channels and other available TV channels. You must use these channels if they are available. You do not need to register reserved channels and other available TV channels that you are using.

The registration process provides interference protection from TV white space devices. Large venues or major events that cannot accommodate all of their wireless microphones and other low power auxiliary devices on the reserved channels and other available TV channels can register for protection on additional channels. Major sporting events and live theatrical productions or shows are examples of major events that might qualify for registration

You do not need to register in order to operate a wireless microphone or other low power auxiliary device. The FCC has waived its rules to allow you to operate wireless microphones and other low power devices up to 50 milliwatts power on an unlicensed basis.

What if my equipment does not operate on the reserved channels or other available TV channels?

You are expected to obtain equipment that can operate on all of the reserved and other available channels at the venue's location. You will not qualify for registration if you do not first have equipment for, and use, all of the reserved channels and other available channels at the venue's location.

How long before an event do I need to file for registration in order to receive protection?

Requests for registration must be filed at least 30 days prior to operation. Registrations that do not fall clearly within the class of major events/productions, cover a large area, or request numerous TV white space channels may take longer to process. In these instances you should consider filing registrations further in advance to provide more time for review.

What should I do if I need a registration in less than 30 days?

You must request a waiver of Rule 15.713(h)(9) to file a registration less than 30 days prior to operation. If requesting a waiver respond "Yes" to the waiver question on the Waiver and Certification screen and attach an exhibit with information sufficient to justify a waiver.
