Important Alert

Days Passed the Deadline!

NARROWBAND
150-512 MHz DEADLINE 01/01/2013!

<

 


THE NARROWBANDING DEADLINE OF JANUARY 1, 2013 HAS PASSED AND ACTION NEEDS TO BE TAKEN NOW BY LICENSEES TO PLAN ON CHANGING OUT NON-COMPLIANT EQUIPMENT. MOST VHF and UHF EQUIPMENT OLDER THAN 8-10 YEARS MAY NO LONGER BE LEGAL TO USE AFTER THE DEADLINE.

From the FCC Notice of Proposed Rules, Released 3-11-2010 **Removes coordination requirement - analog narrowband modifications**

From the FCC Narrowbanding Notice, Released 12-23-04

Executive summary of the FCC order:

  • FCC establishes January 1, 2013 deadline for migration to 12.5 KHz technology.
  • The order affects systems on VHF and UHF channels between 150 and 512 MHz,
  • Applications for wideband operations (25 KHz channels) will NOT be accepted after January 1, 2011.
  • Application for modification of operations that expand the authorized contour of an existing station using 25 KHz channels will NOT be accepted after January 1, 2011.  (Also applies to "new" systems submitted for licensing.)
  • Part 90 “paging-only” frequencies are exempt from this ruling.
  • Low Band VHF systems BELOW 150 MHz are not affected by this ruling.

PROMOTION OF SPECTRUM EFFICIENT TECHNOLOGIES ON CERTAIN PART 90

FREQUENCIES.   (Dkt No.   99-87). Action by:  By the Commission:   Adopted:  12/20/2004 by MO&O. (FCC No. 04-292).

What This Means To LICENSEES

     

All existing Part 90 radio systems operating on frequencies between 150-512 MHz have to convert those systems either to 12.5 kHz bandwidth or to a technology that provides one voice path per 12.5 kHz of bandwidth or provides a data rate of 4800 bps/6.25 kHz.  This Deadline is not expected to be extended any further by the FCC, having done so once already.  Licensees

will be required to certify to the Commission that they have made the technical necessary changes and are using narrowband equipment.  Licensees that do not meet this deadline will be cancelled by the FCC and relicensing of cancelled systems will become very difficult. 

 

FIT will provide License modifications and assistance with any certification notice to the Commission as a service to our MEMBERSHIP.     

 

 

NEW NARROWBAND EFFICIENCY STANDARDS

    • One voice channel/12.5 kHz bandwidth or 4800 bps/6.25 kHz (9600 bps for 12.5 kHz; 19.2 bps for 25 kHz)

12.5 kHz Conversion Deadline for Existing VHF/UHF Systems   

  • Both Industrial and Public Safety licensees have the same deadline for conversion of their systems to narrowband operation:  January 1, 2013.

Interim Deadlines for VHF/UHF Systems & Equipment

  • New applications for 25 kHz bandwidth will be accepted until January 1, 2011
  • Modifications of existing 25 kHz systems will be accepted until January 1, 2011
  • 25 kHz equipment can be manufactured and imported until January 1, 2013 
  • The FCC exempts Part 90 “paging-only” frequencies from the new Rules
  • Low Band VHF systems (30-50 MHz) are not required to be narrowbanded.

THE BASICS

 

Narrowbanding does not require moving to another frequency band.  You reduce the bandwidth of the channel(s) you are now using.

 

Most radios purchased in the last 6-8 years are already narrowband capable.  They only need to be re-tuned or re-programmed by a technician to comply with the Rules.  Check with your dealer or service shop to identify which units may need to be replaced.

 

Your coverage will remain approximately the same.  Only a thorough analysis of your coverage requirements can tell for sure.

 

You do not have to convert to digital.   However, many licensees are using this opportunity to upgrade to digital technology.  Most digital radios are dual mode capable and can operate in wideband analog as well as narrowband analog and digital.  Digital is also more immune from adjacent channel interference and has new features that are unavailable in analog.

 

If your radios are not narrowband capable, you will have to spend money for new equipment and expect to spend money for retuning of existing dual-mode radios. The dates are extended to ensure most licensees have fully amortized the value of their current equipment by the time the mandates kick in.  You need to PLAN IMMEDIATELY for how you will transition to narrowband operation and begin any equipment upgrades. Plan, Budget and Act!  Do not wait!

 

You needed to certify to the FCC by 1/1/2013 that you had made the conversion. Its not too late to file, the FCC is still accepting applications.  Relicensing  cancelled systems will not be a easy process and the FCC has indicated that they will not easily grant waivers for continued wideband operation after the deadline.
