FCC Part 74 Licensing

Professional Wireless provides licensing service for Large Venue Owners and Operators, Professional Sound Companies and Technicians.

Users who routinely work with 50 or more frequencies are eligible to apply for and be protected under the FCC’s Low Power Broadcast Auxiliary (LPBA), Part 74 License providing immediate access to the white space database and offering the right to reserve necessary frequencies for a production or event. PWS offers users the ability to apply for a Part 74 license.

The Part 74 License will allow Licensed operation of wireless mics, wireless in ear monitors, and wireless communications in the following bands. The Part 74 License does not cover operation in any ISM band (915MHz, 2.4GHz, 5GHz) nor does it cover Land-Mobile radios in the 450MHz band.

Professional Wireless guarentees to file your licenses within 14 days of your purchase. After the FCC has received the license application from Professional Wireless the wait time will vary but has recently taken as little as 10 days.

Professional Wireless charges $500 per license. This price covers the FCC’s filing fee of $160, and a guarentee of successful licensure.

For the context of the Part 74 License Professional Wireless defines routinely as once a month or anything more frequent. For example, a House of Worship that uses 20 wireless microphones every week but needs 50 wireless mics only twice a year would not qualify.

A Part 74 license is valid for 10 years from the Granted Date by the FCC.

Only once you have received your unique Callsign can you register your event with any of the White Space Database Administrators.

A Part 74 license does not provide the holder with exclusive frequencies. It provides licensed operation in the UHF(470-698MHz), VHF-High(174-216MHz) and VHF-Low(54-72MHz, 76-88MHz) bands for as many devices as listed, up to the maximum transmit power. Professional Wireless files licenses for 200 devices in the VHF, and 550 in the UHF. You can reserve specific TV channels in the White Space Database for your protection and operate at 250mW in the UHF band.

After the auction you will continue to be licensed and frequency agile in the remaining UHF spectrum for wireless mics. The FCC will modify your license to reflect the change and PWS will notify you of the changes as well to your license.

While there may not be immediate dangers from neighboring TV Band Devices sharing our spectrum, the Database is going to become our collective resume of all the events around the country that use wireless mics and require their own dedicated spectrum. When the time comes for the FCC to reevaluate the remaining UHF spectrum -and that time will come, UHF is the beachfront property of radio waves- it will be in the industry’s favor to have a vast and detailed list of our activity. Unlicensed events occur every day without an official record and have already suffered the consequences of such. Squandering such a service is not in the interest of any licensed user.
