This article provides information on how to file a narrowbanding application in the Universal Licensing System (ULS).
The key part of filing a narrowbanding application involves the emission designator. You can either modify an existing emission designator to change it from a wideband designator to a narrowband designator, or you can add a narrowband emission designator, and keep the wideband emission designator. If you modify the existing emission designator to change it from a wideband designator to a narrowband designator, you will need to begin operating the narrowband frequencies no later than the date that the FCC grants narrowbanding application. If you add a narrowband emission designator and keep the wideband emission designator, too, you have until the narrowbanding deadline of January 1, 2013, to begin operating the narrowband frequencies.
Note: An application that alters other technical parameters such as changing from analog to digital emissions is not a straight narrowbanding application and will require frequency coordination.
An overview of narrowbanding can be found in the FCC’s guide to narrowbanding .

FAQs – Filing a narrowbanding application in ULS
Do narrowbanding applications require frequency coordination?
No. A “straight” narrowbanding modification application does not require frequency coordination (pursuant to Section 90.175(j)(20) of the Commission’s Rules, 47 C.F.R. § 90.175(j)(20)). A straight narrowbanding modification application is an application to modify a license by deleting a wideband emission designator (occupied bandwidth in excess of 11.25 kHz) or adding one or more narrowband emission designators to or in place of a wideband emission designator – but not changing the existing frequencies, emission types (the last three characters of the emission designator), locations, or other technical parameters of the license.
Note: An application that reduces the occupied bandwidth but also alters other technical parameters, such as changing from analog to digital emissions, is not a straight narrowbanding modification application and requires frequency coordination.
Do narrowbanding applications require payment of a Commission fee?
No. A “straight” narrowbanding application does not require payment of Commission fees (pursuant to Section 1.1116(a) of the Commission’s Rules, 47 C.F.R. § 1.1116(a)).
Straight narrowbanding applications are fee-exempt pursuant to Section 1.1116(a) of the Commission’s Rules, which exempts applications filed for the sole purpose of modifying a license in order to comply with new requirements of the Commission’s rules.
To file under the fee exemption, the applicant filling out FCC Form 601 must enter ‘yes’ responses to Items 9 (exempt from the application fee) and 10 (exempt from the regulatory fee). In addition, the applicant must respond ‘yes’ to Item 8 on Form 601 and submit an attachment explaining why the application is fee-exempt. The attachment type should be the 'fee exemption' attachment. It is recommended that licensees reference Section 1.1116(a) in the attachment explanation field and indicate that the filing was made exclusively to comply with the Commission's narrowbanding mandate.
