3 9/14/2011 Page 3 APCO NENA Annual Training Conference 2011 History and Background More efficient use of Part 90 spectrum –VHF (150 – 174 MHz) –UHF ( MHz) Licensees –Reduce operations from 25 kHz channels to 12.5 kHz or less –January 1, 2013 –FCC recommends migration to 6.25 kHz –No date licensees must operate 6.25 kHz MFGs –Prohibited from new 25 kHz radios now –Must include 6.25 kHz after 1/1/2013

4 9/14/2011 Page 4 APCO NENA Annual Training Conference 2011 NPSTC Petition & FCC Order June 30, 2010 Extended to 1/1/2013 the manufacture/import of 25 kHz equipment But…no new applications for new 25 kHz equipment Extended to 1/1/ kHz in all new radios No new 25 kHz system licenses

5 9/14/2011 Page 5 APCO NENA Annual Training Conference 2011 Not Included Part 22 Frequencies Paging-Only Frequencies Are Excluded: –VHF Public Safety – and MHz; –VHF and UHF Business/Industrial Paging Only Frequencies; 800/900 MHz Public Safety/Business/Industrial Pool Channels; 700 MHz Public Safety channels (handled in another proceeding); Important Notes: – MHz MUST be narrowbanded – See Detroit Medical Center, DA , released March 7, 2006; Report and Order, ET Docket No , released March 11, –Paging systems operating on voice channels must narrowband! Marine Operations Amateur Radio Service

6 9/14/2011 Page 6 APCO NENA Annual Training Conference kHz Equivalent Efficiency Voice Operations –One Voice Channel Per 12.5 kHz of Bandwidth –Two Voice Channels Per 25 kHz of Bandwidth Data Operations –4800 Bits Per Second Per 6.25 kHz of Bandwidth –9600 BPS Per 12.5 kHz of Bandwidth –19,200 BPS Per 25 kHz of Bandwidth

7 9/14/2011 Page 7 APCO NENA Annual Training Conference kHz Equivalent Efficiency Voice Operations –One Voice Channel Per 6.25 kHz of Bandwidth –Two Voice Channels Per 12.5 kHz of Bandwidth –Four Voice Channels Per 25 kHz of Bandwidth Data Operations –4800 Bits Per Second Per 6.25 kHz of Bandwidth –9600 BPS Per 12.5 kHz of Bandwidth –19,200 BPS Per 25 kHz of Bandwidth

8 9/14/2011 Page 8 APCO NENA Annual Training Conference 2011 Q – If I dont 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.

9 9/14/2011 Page 9 APCO NENA Annual Training Conference 2011 Q – Im 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)

10 9/14/2011 Page 10 APCO NENA Annual Training Conference 2011 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

11 9/14/2011 Page 11 APCO NENA Annual Training Conference 2011 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

12 9/14/2011 Page 12 APCO NENA Annual Training Conference 2011 Q – Must I obtain digital equipment to meet the narrowbanding mandate ? No Analog equipment is acceptable

13 9/14/2011 Page 13 APCO NENA Annual Training Conference 2011 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

14 9/14/2011 Page 14 APCO NENA Annual Training Conference 2011 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

15 9/14/2011 Page 15 APCO NENA Annual Training Conference 2011 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 kHz channels is imminent

16 9/14/2011 Page 16 APCO NENA Annual Training Conference 2011 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 Receivers IF bandwidth Consult with your manufacturer and/or your consulting engineer

17 9/14/2011 Page 17 APCO NENA Annual Training Conference 2011 Q – I am interested in moving directly to 6.25 kHz equipment, but Id like to also go P25. Is such equipment available? P25 Phase kHz TDMA equipment Manufacturers are now designing radios

18 9/14/2011 Page 18 APCO NENA Annual Training Conference 2011 Q – My repeaters are not dual mode. There are third party kits that Ive 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 (a). Reducing deviation and frequency stability is insufficient Must be narrowband type certified

19 9/14/2011 Page 19 APCO NENA Annual Training Conference 2011 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

20 9/14/2011 Page 20 APCO NENA Annual Training Conference 2011 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

21 9/14/2011 Page 21 APCO NENA Annual Training Conference 2011 Practical Impact to Dispatch

25 9/14/2011 Page 25 APCO NENA Annual Training Conference 2011 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
