The FCC deadline is here, are you ready?
The FCC recently defined the potential enforcement consequences
to VHF/UHF licensees of failing to narrowband by January 1, 2013.
They can be found at the bottom of page 5 of their Public Notice from July 13, 2011.
It reads as follows:
What are the potential enforcement consequences to VHF/UHF licensees of failing
to narrowband by January 1, 2013? As of January 1, 2013, the Commission’s rules
will prohibit Industrial/Business and Public Safety Radio Pool licensees in the
150-174 MHz and 421-512 MHz bands from operating with wideband channels
(unless their equipment meets the narrowband efficiency standard), even if the
license still lists a wideband emission designator. Licensees operating in wideband
mode after January 1,2013 that have not received a waiver from the Commission
extending the deadline will be inviolation of these rules. Operation inviolation of
the Commission’s rules may subject licensees to appropriate enforcement action,
including admonishments, license revocation, and/or monetary for feitures of up to
$16,000 for each such violation
...or each day of a continuing violation
and up to $112,500 for any single act
...or failure to act (11).
Understanding FCC Narrowbanding Requirements
The Federal Communications Commission mandated a move to 12.5 kHz
narrowband voice channels by January 1, 2013 to increase spectrum
efficiency and to accommodate more users.
Planning for the Move to Narrowband
Now is the time to take inventory of your equipment to verify that it
is 12.5 kHz capable. While Motorola radios purchased in the last
ten years are likely 12.5 kHz capable, older equipment may need to be
replaced.
- Start planning – the 1st FCC deadline is not very far away: January 1, 2011.
- Assess your current equipment
- Obtain new or modified licenses

Understanding FCC Narrowbanding Requirements
- Key Points About FCC Narrowbanding Requirements
- Most current public safety radio systems use 25 kHz-wide channels.
- The
Federal Communications Commission (FCC) has mandated that all
non-Federal public safety licensees using 25 kHz radio systems migrate
to narrowband 12.5 kHz channels by January 1, 2013.
- Agencies that do not meet the deadline face the loss of communication capabilities.
- Agencies
need to start planning now to migrate to narrowband systems by
assessing their current radio equipment and applying for new or
modified licenses.
Overview
Figure 1: Narrowband channels allow additional channels to exist in the same spectrum.
Private
land mobile radio (LMR) systems—including municipal government and
State and local public safety systems—use blocks of radio spectrum
called channels. (See Radio Spectrum9766.) Historically, LMR systems
have used 25 kHz-wide channels. In December 2004, the Federal
Communications Commission mandated that all private LMR users operating
below 512 MHz move to 12.5 kHz narrowband voice channels and highly
efficient data channel operations by January 1, 2013.
This migration complements a National Telecommunications and
Information Administration mandate for more rapid Federal agency
migration to 12.5 kHz narrowband operation by January 1, 2008. The
earlier Federal deadline affects State and local FCC licensees that
interface or share frequencies with Federal radio systems.
Using
narrowband channels will ensure that agencies take advantage of more
efficient technology and, by reducing channel width, will allow
additional channels to exist within the same spectrum space, as
illustrated in figure 1.
Deadlines
To phase
in the migration deadline of January 1, 2013, the FCC has established
interim deadlines. The first important deadline is January 1, 2011,
after which:
- The FCC will not grant
applications for new voice operations or applications to expand the
authorized contour of existing stations that use 25 kHz channels. Only
narrowband authorizations will be granted.
- The FCC will
prohibit manufacture or importation of new equipment that operates on
25 kHz channels. This will reduce the availability of new equipment for
legacy radio systems and will affect how agencies maintain and
upgrade older systems.
Planning for the Move to Narrowband
Public
safety agencies need to aggressively develop a strategy to meet
narrowband deadlines to avoid cancellation of existing wideband FCC
authorizations. Although the migration deadline may seem far off, the
long lead time and interim deadlines make it necessary for agencies to
plan well in advance.
Assess current equipment and start planning.To
prepare for the migration, public safety agencies should start
assessing their radio systems and planning for replacements or
upgrades. They should inventory their current equipment to ascertain
what can be converted to 12.5 kHz and what will need to be replaced
before January 1, 2013. Most new equipment has the capability for both
25 kHz and 12.5 kHz operation because any VHF/UHF radio equipment
accepted by the FCC after February 14, 1997, had to have 12.5 kHz
capability. The 2.5 kHz narrowband equipment is available in both
conventional analog FM and digital formats (such as Project 25), so
narrowband conventional FM systems will be compliant. Local governments
should develop contingency plans to accommodate system changes for
both public safety and nonpublic safety systems.
Obtain new or modified licenses.To
move to narrowband operations, agencies must apply for new
frequencies or modify existing licenses. An agency that is licensed
for a 25 kHz-wide channel is not guaranteed two 12.5 kHz channels.
Licensees will have to justify to the FCC why they need additional
channels. Consideration of applications for new narrowband licenses
will follow the same process as a new license application. As agencies
migrate to narrowband
operation, however, the pool of available frequencies will increase.
VHF/UHF Narrowbanding FAQs
Below is a collection of general questions on Narrowbanding.
- What is Narrowbanding?
- Narrowbanding
is an effort to ensure more efficient use of the VHF and UHF
spectrum by requiring all VHF and UHF Public Safety and
Industrial/Business land mobile radio (LMR) systems to migrate to at
least 12.5 kHz efficiency technology by January 1, 2013.
More
specifically, all existing Part 90 radio systems operating in the
150-174 MHz and 421-512 MHz bands have until January 1, 2013 to
convert those systems either to a maximum bandwidth of 12.5 kHz or to a
technology that provides at least one voice path per 12.5 kHz of
bandwidth or equivalent efficiency.
- What does Equivalent Efficiency mean?
- Any of the following meet the 12.5 kHz equivalent efficiency requirement:
- One voice path in a 12.5 kHz channel
- Two voice paths in a 25 kHz channel
- Data
operations on channels greater than 12.5 KHz must employ data rates
greater than 4.8 kbps per 6.25 kHz channel, such as 19.2 kbps per 25
kHz channel
-
- What is the purpose of Narrowbanding?
- Currently,
the majority of UHF and VHF LMR licensees operate using 25 kHz
efficiency technology. However, the UHF and VHF frequency bands are
congested with limited spectrum available for system expansion or
implementation of new systems. The migration to 12.5 kHz efficiency
technology will require licensees to operate more efficiently, either on
narrower channel bandwidths or increased voice paths on existing
channels. This will allow creation of additional channels within the
same spectrum, thereby supporting more users.
- What frequency bands are subject to the Narrowbanding mandate?
- The 150-174 MHz and 421-512 MHz bands are subject to the Narrowbanding mandate.
-
- Are paging-only channels exempt from Narrowbanding?
- Yes, however, there are only 14 paging-only channels.
- 152.0075 and 157.4500 MHz in the Public Safety Pool
- 152.480,
157.740, 158.460, 462.750, 462.775, 462.800, 462.825, 462.850,
462.875, 462.900, 462.925, and 465.000 MHz in the Business Industrial
Pool.
Note that Med Channels 163.250, 150.775 and
150.790 MHz are not exempt, as these channels are shared with
Federal Government users who must Narrowband as part of the Federal
Government Narrowbanding effort.
Puerto Rico and the
U.S. Virgin Islands have the following five additional paging only
frequencies in the Business Industrial Pool: 150.83, 150.92, 151.07,
151.19 and 151.31.
- What is the difference between the January 1, 2011 interim deadline and the January 1, 2013 final deadline?
- After
January 1, 2011, the Commission will only accept applications for
new licenses or modification applications that expand an existing
service area for systems that operate using 12.5 kHz efficiency.
After
January 1, 2011, the Commission will not certify VHF/UHF equipment
that has a 25 kHz mode. Providers may still sell equipment with a 25
kHz mode after that date, if it was manufactured/imported prior to
January 1, 2013.
After January 1, 2013, all licensees must operate in at least 12.5 kHz efficiency.
After January 1, 2013, the Commission no longer allows manufacturing or importation of equipment that includes a 25 kHz mode.
- What
will happen if I fail to comply with the FCC Narrowbanding mandate?
Can I continue to operate at 25 kHz efficiency on a secondary status
after January 1, 2013?
- No. Licensees are prohibited from
operating 25 kHz efficiency equipment after January 1, 2013.
Non-compliance will be considered a violation that could lead to FCC
enforcement action, which may include admonishment, monetary fines, or
loss of license.
-
- If I need to Narrowband, do I need to implement digital technology?
- No. Licensees can operate in either analog or digital formats as long as they operate at 12.5 kHz efficiency.
-
- Does Narrowbanding require me to change frequencies or obtain new channels?
- No.
Narrowbanding does not require moving to another frequency band or
different channels. Licensees stay on the same channel center(s), but
reduce the bandwidth of the channel(s) currently used, from 25 kHz to
12.5 kHz and change the emission designator on the license.
Alternatively, licensees may stay on the same 25 kHz channel but
implement a 12.5 kHz equivalent technology on that channel.
-
- If
I currently have a license for a 25 kHz channel, will I
automatically be entitled to license two 12.5 kHz channels after I
Narrowband?
- No. Your 12.5 kHz channel will remain on the same
25 kHz channel center. Your current 25 kHz channel will not be split
into two 12.5 kHz channels. You will need to justify and apply for
additional 12.5 kHz channels through a certified frequency
coordinator.
-
- Will I lose coverage area when I Narrowband?
- It has been estimated that Narrowband compliance can result in a 3 dB
loss in signal strength. However, this rule of thumb is based upon a
"plain vanilla" Narrowbanding scenario where a 25 kHz analog system
converts to a 12.5 kHz analog system. Consult with a manufacturer
and/or consulting engineer for a better estimate of how Narrowbanding
will affect your particular system.
-
- Has the FCC established a schedule for mandatory migration to 6.25 kHz efficiency?
- No. The Commission has not set any date by which licensees must
operate in 6.25 kHz efficiency. The current mandate only requires
users to migrate to 12.5 kHz efficiency by January 1. 2013.
-
- Are governmental entities other than traditional public safety entities subject to the Narrowbanding mandate?
- Yes. Below is a partial list of the types of governmental entities that could be subject to the Narrowbanding mandate.
- Public Utilities – both traditional voice and Supervisory Control and Data Acquisition (SCADA) systems
- Schools (including school buses)
- Transportation Departments
- Mass Transit Agencies
- Community Watches
In addition, licensees should remember to include the following types of radios in their Narrowbanding efforts.
- Cache Radios – Transportable Systems
- Command Post/Communications Vehicles
- Mutual Aid Gateways
