FCC Extends Interim Narrowbanding Deadlines

Back to News Listing

The Federal Communications Commission (FCC) has extended two of the interim deadlines associated with Part 90 narrowbanding.  On January 1, 2013, all public safety and business industrial land mobile radio systems operating in the 150-174 MHz and 421-512 MHz radio bands must cease using 25 kHz efficiency technology, and begin operating using at least 12.5 kHz efficiency technology.

In order to provide some relief to parties concerned that the interim narrowbanding deadlines could frustrate the migration to narrowband technologies, the FCC extended to the following dates certain deadlines originally set to take effect January 1, 2011:

  • January 1, 2013:  Extended the deadline on the manufacture or importation of equipment that includes a 25 kHz mode to facilitate conversion of existing systems to narrowband technologies.
  • January 1, 2013:  Extended the deadline for manufacturers to incorporate a 6.25 kHz capability in equipment that is submitted for equipment certification.

The FCC retained the overall January 1, 2013, deadline for the conversion to narrowband technologies.  The FCC also retained the deadline of January 1, 2011, for the filing of applications for new or modified licenses proposing 25 kHz operation.  Case-by-case relief of this licensing deadline may be available through the waiver process.
