     Q – If I don’t narrowband my
     system, can I operate on a
     secondary basis after 1/1/2013

     A – No. The FCC has stated that failure to
     narrowband “… may subject licensees to
     enforcement action, including admonishments,
     monetary forfeitures, and/or license revocation,
     as appropriate.”

APCO NENA Annual Training Conference 2011   9/14/2011 Page 8
        Q – I’m about to narrowband my system, and now I
          need to fix my FCC license. What should I do?

 • Currently 25 kHz
       – File an FCC application for the proper
         narrowband emission designator
       – Provide a certification to the FCC of
         narrowband operation prior to 1/1/2013
 • Currently 12.5 kHz
       – Update your license for the correct emission
         designator (if not done already)

APCO NENA Annual Training Conference 2011   9/14/2011 Page 9
    Q – Do applications which only add, amend or delete
    an emission designator have to go to the Frequency
                Advisory Committee (FAC)?

   • Narrowband a wideband analog emission
     designator…No
         – Emission Designator greater than 11K, need
           to change your emission designator
   • Changing your emission type (i.e. going
     from analog to digital)…Yes


APCO NENA Annual Training Conference 2011   9/14/2011 Page 10
                          Q – Must I buy new equipment?


 • Not necessarily
 • Equipment purchased after 1998 is likely
   dual mode
 • Able to operate both 25 kHz and 12.5 kHz
 • Enable the 12.5 kHz mode
 • Disable the 25 kHz mode in each radio



APCO NENA Annual Training Conference 2011   9/14/2011 Page 11
         Q – Must I obtain digital equipment to meet the
                           narrowbanding mandate                ?
• No
• Analog equipment is acceptable




APCO NENA Annual Training Conference 2011   9/14/2011 Page 12
         Q – I am a public safety licensee. Must I put in P25
           equipment as part of my narrowband project?


  • No FCC requirement to utilize P25
    equipment for your narrowband project

  • P25 is an interoperability decision, not an
    FCC mandate

  • Note: some grants require P25 capability

APCO NENA Annual Training Conference 2011   9/14/2011 Page 13
    Q – When I reduce my bandwidth from 25 kHz to 12.5
       kHz, will I automatically double my channels?

 • No

 • Narrowbanding from 25 kHz to 12.5 kHz
   enables full power, non-interfering use of
   adjacent 12.5 kHz channels

 • But…you are not automatically licensed
   for those adjacent channels
APCO NENA Annual Training Conference 2011   9/14/2011 Page 14
      Q – Do I need to change my channel centers when I
                         narrowband?
 • No
 • You maintain your existing channel
   centers
 • FCC approval of the LMCC request to split
   a 12.5 kHz channel into 2 ea. 6.25 kHz
   channels is imminent



APCO NENA Annual Training Conference 2011   9/14/2011 Page 15
          Q- Will I lose coverage area when I narrowband?

 • It depends…
 • May be a 3 dB loss simply going from 25
   kHz to 12.5 kHz analog
 • If…no consideration of static or faded
   sensitivity
 • If… no consideration of the Receiver’s IF
   bandwidth
 • Consult with your manufacturer and/or
   your consulting engineer
APCO NENA Annual Training Conference 2011   9/14/2011 Page 16
           Q – I am interested in moving directly to 6.25 kHz
            equipment, but I’d like to also go P25. Is such
                         equipment available?

 • P25 Phase 2
 • 12.5 kHz TDMA equipment
 • Manufacturers are now designing radios




APCO NENA Annual Training Conference 2011   9/14/2011 Page 17
      Q – My repeaters are not dual mode. There are third
     party “kits” that I’ve heard about which could alter the
     repeaters to operate at 12.5 kHz. Is such an alteration
                            permissible?

• “… using these kits to modify the radio
  entails a hardware modification..”
• “…requires a new equipment certification
  and a new FCC ID (See 2.1043(a).”
• Reducing deviation and frequency stability
  is insufficient
• Must be narrowband type certified
APCO NENA Annual Training Conference 2011   9/14/2011 Page 18
        Q – I am going from wideband (25 kHz) to narrowband
        data (12.5 kHz). Will I still need to meet the FCC's data
                          equivalency rule?


   • Yes
   • Even operating at 12.5 kHz
   • Need a data speed of at least 9600 bps
     per each 12.5 kHz of occupied spectrum




APCO NENA Annual Training Conference 2011   9/14/2011 Page 19
       Q- What can happen if we don't move to narrowband
                          operation?

 • License will be in violation of FCC Rules
 • Subject to FCC enforcement action
       – Monetary fine
       – Admonishment
       – Loss of license
 • FCC Public Notice 7/13/2011
       – Must request a waiver for extension in 2011
       – Subject to a high level of scrutiny

           • Impacts all radios in fleet
                      • Mobiles
                      • Portables
                      • Repeaters/Base Stations

           • Not all radios/repeaters can be narrowbanded
                      • Inventory
                           – Identify Wideband only equipment
                           – List of radio types that will need to be reprogrammed
                      • Radio Sites may not be accessible year round

           • Limited Resources for Reprogramming
                      • Supply of Radio Technicians is limited
                           – Supplement in-house resources with dealers
                           – Don't wait until the last minute!



           • Plan reprogramming to minimize wideband/narrowband
             mismatches
