Tech Topic 16: Narrow Banding Public Safety Communication
Channels
Public safety communications continue to evolve today as more challenging user requirements and technology
considerations put pressure on municipalities and their local public safety organizations to enhance and improve
their systems. Public safety voice communications have been the predominant mission critical
communications "need" historically and will be for the foreseeable future. For the most part, these voice
requirements have been met by communications operations in pre-defined (channelized) spectrum allocated by the
Commission. On the other hand, the evolution to other services such as data and video applications is increasing
the demand for higher capacity channels and is driving the need for improved spectral efficiency for public safety
spectrum allocations. The FCC has undertaken a number of efforts to assist in a variety of ways including (1)
allocating more public safety frequency bands, (2) increasing available communications channels within limited
spectrum bands, (3) improving spectrum management processes to enhance efficiency, and (4) promoting
technology advancement such as software defined radio and cognitive radio, etc. (See our earlier Tech Topics on
these subjects!) This topic presents a cursory view of the Commission's efforts to enhance public safety spectral
efficiency by moving to narrower channel allocations.
The origins of public safety radio systems rest with traditional analog radio systems and the historical allocations for
public safety radio are based on the use of analog technologies. However, recent efforts at improving spectral
efficiency have focused on migrating to digital techniques as an effective way of improving spectral efficiency without
increasing overall bandwidth or reducing the quality of public safety communications. Coincident with the advances
in digital technologies was a corresponding decrease in the required spectrum bandwidth to maintain the same
quality of service for a given voice channel. As a result, it was possible to increase the spectral efficiency of public
safety spectrum allocations. This was accomplished by reducing the single voice channel bandwidth from the
traditional analog value of 25 kHz to a value 12.5 kHz and further down to 6.25 kHzl. In this way, the availability of
usable channels was effectively doubled or quadrupled in the same equivalent bandwidth. Narrowbanding, as the
process has become known as (a.k.a. 'refarming'), has been used to improve spectrum efficiency especially in the
crowded VHF high (150-170 MHz) and UHF (421-512 MHz) land mobile radio (LMR) frequency bands. In other
bands at 700 MHz and 800 MHz, initial allocations started with more efficient band plans.
In December 2004, the Commission ruled that all private land mobile radio users operating below 512 MHz must
move to 12.5 kHz narrowband voice channels and highly efficient data channel operations by the end of the year of
20122.. The rule implies mandatory narrow banding implementation by not allowing any new licenses for devices and
equipment with 25 kHz wide channels after January 1, 2011. By the end of 2012, all legacy communications
systems below 512 MHz should convert to narrowband operation. The rule change has considerable impact
because most current public safety radio systems below 512 MHz still use 25 kHz voice channels. Thus, all
municipal government and state and local public safety systems using 25 kHz radio systems must migrate to 12.5
kHz narrowband voice channels by the end of 2012. This does not necessarily imply that any public safety agency is
automatically guaranteed two 12.5 kHz channels from a previously licensed 25 kHz channel. To migrate to
narrowband operations, public safety agencies must apply for new narrowband licenses or modify existing licenses
while justifying channel requirements by that deadline.
In response to the FCC narrowbanding initiative, industry began a process to develop a set of standards for use on
public safety land mobile radio channels. Under a program called Project 25 (P25), the Telecommunications Industry
Association (TIA) along with the Association of Public Safety Communications Officials - International, Inc. (APCO
International), a public safety communications advocacy organization, have been instrumental in development of a

standardized digital voice trunked system that accommodates and manages multiple signal channels for the digital
LMR services for local, state and federal public safety communications~. The standard is based on a 12.5 kHz
channel bandwidth utilizing a digital modulation technique called constant envelope 4-ary frequency modulation
(C4FM) and frequency division multiple access (FDMA) as a channel access methodology. The development of the
standard will eventually evolve to 6.25 kHz channel bandwidth with continuous quadrature phase shift keying
(CQPSK) modulation and time division multiple access (TDMA) in the future. At present, the aggregate data rate for
a 12.5 kHz channel is 9.6 kbps while covering a typical cell radius of 5 to 20 miles.
As compared to spectrum below 512 MHz, the Commission's more recent 700 MHz and 800 MHz public safety
allocations started with more efficient channelization plans. For example, in a series of rulemakings beginning in
1997, following a mandate from Congress, the Commission allocated 24 megahertz of spectrum located in the 700
MHz band for public safety use (763-775 and 793-805 MHz).~ The Commission designated spectrum in the 700
MHz Public Safety Band for use as follows: 12.5 megahertz for General Use, 2.6 megahertz for Interoperability, 2.4
megahertz for State License, 0.3 megahertz for Low Power, 0.2 megahertz for secondary trunking, and 6.0
megahertz for reserve. The Commission divided the 24 megahertz of spectrum into 12 megahertz of paired
narrowband (6.25 kHz channel) and 10 megahertz for paired broadband, with two megahertz of paired guard band
between the narrowband and broadband allocations. Since 1997, the Commission has considered and adopted a
series of operational and technical rules governing this spectrum. The current narrowband channel allocation
document can be seen here.
Thus, the allocation of the 700 MHz narrowband public safety channels started with more efficient channelization
than was originally the case with spectrum below 512 MHz. Using narrowband channels will ensure that public
safety communications users take advantage of more efficient technology and, by reducing channel width, will allow
additional channels to be assigned. In this regard, narrowbanding improves spectrum efficiency for public safety
communications and it helps to some degree with interoperability in the near future. Achieving true interoperability
will require resolving complex issues intertwining many practical elements such as communications standards
conformance, operational procedures, applications, security (encryption/decryption) methods, spectrum coordination
and monitoring, and many others. For example, even P25 compliant radio systems are typically operating in only a
single frequency band and set only one encryption type (either DES or AES) at a time. This means that without
previous coordination among users, P25 devices cannot talk to each other due to frequency incompatibility,
encryption incompatibility, or both.
The migration to narrowband channels below 512 MHz has not been smooth or problem free. In addition to the slow
(and still ongoing) development of the APCO P25 standards, a number of problems have arisen regarding the
quality of the digital services provided over the reduced bandwidth channels. Most of the problems have been
associated with the development of voice encoders/decoders. The reduced channel bandwidth puts an extreme
burden on the signal processing capabilities of the radios, thereby making the quality of service difficult to meet in
terms of the acceptable channel bit rates. With enhanced digital coding techniques, it is hoped that the quality of
voice services on the reduced channels can be met.
The move to narrower channels has been an important and ongoing effort by the Commission. In conjunction with
the 700 MHz narrowband public safety allocations, the rebanding currently underway in the 800 MHz band should
provide public safety users with adequate spectrum to provide for essential mission critical voice communications.
The requirements for new applications that require broadband spectrum allocations will be the topic of a future Tech
Topic!
