Title: 12.5 kHz Narrowbanding


1
12.5 kHz Narrowbanding
The Mandate to 12.5 kHz Operations Meeting the
FCC Narrowbanding Requirements
2
What is Narrowbanding?
  • Federal Communications Commission is mandating
    all Public Safety and Industrial/Business
    licensees must convert existing 25 kHz efficiency
    operations in VHF and UHF to minimum 12.5 kHz
    efficiency analog or digital operation by January
    1, 2013
  • To get there, the FCC set interim deadline
    requirements on licensees and manufacturers
  • FCC has NOT set any date by which licensees must
    operate in 6.25 kHz efficiency

3
Licensee Interim Requirements
January 1, 2011
  • New license applications must specify at least
    12.5 kHz efficiency
  • License modification applications to expand
    authorized service areas must specify at least
    12.5 kHz efficiency

4
Manufacturer Interim Requirements
  • February 14, 1997
  • Radio equipment certification submittals must
    include a 12.5 kHz efficiency mode can be dual
    mode 25/12.5 kHz efficiency
  • January 1, 2011
  • Can no longer certify, manufacture or import 25
    kHz capable equipment must disable mode via
    software
  • New radio equipment certification submittals must
    include a 6.25 kHz efficiency mode can be dual
    mode 12.5/6.25 kHz efficiency

5
Motorolas Support of Narrowbanding
  • Motorola offers the broadest choice of two-way
    radio equipment capable of
  • operating in 12.5 kHz efficiency.
  • Motorola has almost 60 models that operate at
    12.5 kHz.
  • Motorola has been preparing for 12.5 kHz for over
    a decade to enable a smooth transition.
  • All Motorola radios certified since Feb 1997 meet
    the 12.5 kHz capability requirement. Most can
    operate in 12.5 kHz simply with a software
    upgrade.
  • Motorola has experts who regularly work with the
    FCC so we understand the issues and prepare in
    advance.
  • Motorola offers a seamless path to 12.5 kHz,
    allowing you to transition at your own pace.
  • Motorola radios are backwards compatible so they
    can operate in dual mode (12.5 kHz or 25 kHz),
    allowing your organization to transition to 12.5
    kHz at your own pace up to the FCC deadline.
  • Increase capacity and meet the Narrowbanding
    mandate without applying for a second channel.
  • Motorola is shipping two complete product
    families that provide greater than 12.5 kHz
    efficiency.
  • ASTRO 25 with APX radios for mission critical
    applications
  • MOTOTRBO product line for business critical
    applications

Most of Your Motorola Radios Are Probably
12.5kHz Compliant
Motorola offers the broadest choice of two-way
radio equipment with close to 60 models capable
of operating in 12.5 kHz efficiency
  • Motorola radios certified after 1997 are 12.5kHz
    capable
  • Customers operating at 25kHz need to re-program
    or replace radios for 12.5kHz operation by
    January 1, 2013
  • Update FCC license for narrowband compliancy by
    January 1, 2011

Technology Equivalency
Motorola offers a seamless path to 12.5 kHz,
allowing you to transition at your own pace.
  • 12.5 kHz Efficiency
  • One voice path in 12.5 kHz
  • Two voice paths in 25 kHz
  • Data rates 4.8 kbps per 6.25 kHz
  • 9.6 kbps in 12.5 kHz
  • 19.2 kbps in 25 kHz

8
Technology Equivalency

Motorola is shipping two complete product
families that provide greater than 12.5 kHz
efficiency.
  • 6.25 kHz Efficiency
  • One voice path in 6.25 kHz
  • Two voice paths in 12.5 kHz
  • Four voice paths in 25 kHz
  • Data rates 4.8 kbps per 6.25 kHz
  • 9.6 kbps in 12.5 kHz
  • 19.2 kbps in 25 kHz

APXTM P25 Subscriber Family

Narrowband Exceptions
  • Paging is exempt only on the paging channels
  • Can operate at 25 kHz after Jan.1, 2013
  • Paging on any other Part 90 channel must switch
    to 12.5 kHz
  • Low Power (2 watts or less) equipment is exempt
    only from certification for 6.25 kHz efficiency
    mode capability
  • No low power exemption for licensees must
    switch to 12.5 kHz

10
Narrowbanding Myths Truths
  • Licensees must implement digital technology
  • No, narrowband operation in either analog or
    digital is acceptable

11
Narrowbanding Myths Truths
  • Licensees must implement digital technology
  • Licensees end up with twice as many channels
  • No, Narrowbanding will provide greater spectrum
    efficiency, but not additional channels.

12
Narrowbanding Myths Truths
  • Licensees must implement digital technology
  • Licensees end up with twice as many channels
  • Hundreds of new channels will be available in
    2013
  • No, the spectrum allocation will be the same,
    however the spectrum efficiency will be improved

13
Narrowbanding Myths Truths
  • Licensees must implement digital technology
  • Licensees end up with twice as many channels
  • Hundreds of new channels will be available in
    2013
  • Interference may occur to existing 25 kHz systems
  • Yes, narrowbanded channels may adversely impact
    remaining 25 kHz operations and newer
    technologies are more robust than incumbent 25
    kHz systems

14
Narrowbanding Myths Truths
  • Licensees must implement digital technology
  • Licensees end up with twice as many channels
  • Hundreds of new channels will be available in
    2013
  • Interference may occur to existing 25 kHz systems
  • 25 kHz may be continued after January 2013 by
    waiver
  • No, the FCC has provided no such indication

  • Licensees end up with twice as many channels
  • Hundreds of new channels will be available in
    2013
  • Interference may occur to existing 25 kHz systems
  • 25 kHz may be continued after January 2013 by
    waiver
  • A 6.25 kHz date certain will be adopted by the
    FCC
  • Perhaps, but well into the future. The FCC has
    spent over 20 years on the 12.5 kHz Narrowbanding
    initiative. If they moved at lightening speed it
    would take more than 10 years

  • I can request two 6.25 kHz channels from my 12.5
    kHz narrowband license
  • No, the FCC will grant 6.25 kHz channels on the
    existing 6.25 kHz band plan.

Next Steps - Now is the time to start PREPARING
  • Take inventory of your current radio equipment to
    verify it is 12.5 kHz capable
  • Identify radios that can be reprogrammed
  • Identify radios that need to be replaced
  • Review Current System Requirements
  • Operations have likely changed, understand
    potential new system design opportunities
  • Consider narrowband analog performance impact
  • Develop operational and funding plans to replace
    non 12.5 kHz capable equipment
  • Contact Action Communications at 1-308-632-7836
    or 1-800-558-7836 for license modifications,
    equipment replacements or software upgrades.
