FCC license renewal for Part 90 radio systems

The license term

An authorization under the FCC's wireless rules runs for no more than ten years (47 CFR 1.955(a)(1)). Its expiration date is on the license and in the FCC's Universal Licensing System (ULS), and it is the date everything else hangs on.

A licensee holding several authorizations in the same service can ask for a common expiration date so they renew together. Terms can be shortened by up to a year to line them up, but never extended (47 CFR 1.949(b)).

The renewal window is 90 days

A renewal is filed no sooner than 90 days before the expiration date and no later than the expiration date itself, on the same form as an initial application in the service, which for land mobile is FCC Form 601 (47 CFR 1.949(a)).

Because the window only opens 90 days out, a reminder at 90 days is already the opening of the window, not an early warning. A reminder at 180 days is what leaves time to find out who owns the paperwork, confirm the system is still operating the way the license says, and line up whoever files for you.

What happens if nobody files

The authorization terminates automatically on its expiration date, without any action by the FCC, unless a timely renewal application has been filed (47 CFR 1.955(a)(1)). The rule carries no grace period and the FCC sends no notice first. Getting a lapsed license back means a separate request the FCC may or may not grant, which is why the date is worth watching rather than recovering from.

What a renewal asks you to certify

Since 2017 the renewal of a covered license has come with a standard to meet (47 CFR 1.949(d)): over the license term, the licensee provided service to the public, or operated the license to meet its own private, internal communications needs. The covered site-based licenses are listed in 47 CFR 1.907, and they include the Part 90 Industrial/Business Pool, the 800 and 900 MHz SMR and Business/Industrial/Land Transportation channels, private carrier paging, and site-based 220 MHz licenses other than public safety.

A covered site-based license meets the standard through a safe harbor by certifying two things (47 CFR 1.949(e)(1)):

• that it continues to operate consistent with its most recently filed construction notification, or with the authorization itself where no notification was required; and
• that no permanent discontinuance of service occurred during the term.

A licensee that cannot make that certification files a renewal showing instead, describing the service it provided across the whole term (47 CFR 1.949(f)). Every covered renewal also carries a regulatory compliance certification: that the licensee has substantially complied with the FCC's rules and the Communications Act (47 CFR 1.949(g)).

Public Safety Pool licenses are not on the covered list in 47 CFR 1.907, so this standard and its certifications do not apply to them. The 90-day filing window and the automatic termination on the expiration date still do.

The construction clock on a new station

Most Part 90 stations must be placed in operation within twelve months of the grant, or the authorization cancels automatically (47 CFR 90.155(a); the rule lists the exceptions). A base station does not count as placed in operation until at least one of its mobile stations is too (47 CFR 90.155(c)).

The licensee then notifies the FCC on Form 601 within 15 days after the construction period ends, and where only some of a site-specific license's transmitters were built, the notification says which (47 CFR 1.946(d)). Miss the deadline itself and the authorization terminates on the date the construction period expires (47 CFR 1.946(c)).

An extension has to be requested before the construction period ends, and it is granted only for causes beyond the licensee's control. Delays in financing, in getting a site, or in ordering equipment do not qualify (47 CFR 90.155(g), 47 CFR 1.946(e)).

Going quiet has a limit too

A license also terminates automatically if its operation is permanently discontinued during the term (47 CFR 1.953(a)). For covered site-based licenses, and for public safety licenses issued under 47 CFR 90.20 or 47 CFR 90.529, permanent means 365 consecutive days without operating (47 CFR 1.953(c) and (d)). Test signals from a channel keeper do not count as operating (47 CFR 1.953(e)).

A licensee that has permanently discontinued must file for cancellation within 10 days, but the license terminates whether or not the form is filed (47 CFR 1.953(f)). A longer discontinuance period can be requested for good cause, at least 30 days before the 365 days run out (47 CFR 1.953(g)).

A checklist for each license

• The expiration date, and a reminder at least 180 days ahead of it.
• Who files the renewal, and who confirms the system still matches the license.
• For a new or modified station, the construction deadline and the 15-day notification after it.
• Any site that has been off the air, and for how long.
