Reminder from the MABAS Telecommunications and Dispatch Committee Guide from the US Office of Emergency Communications on Narrowbanding
llinois
APCO in cooperation with other State of Illinois Organizations is
participating in a task force for the development of a coordinated
migration plan for public safety agencies under 512 MHz. The FCC has
mandated migration from 25kHz channels to 12.5kHz channels by January
1, 2013. This affects all frequencies below 512mHz (except for
VHF-Low Band). This Committee is dedicated to the coordination of
efforts in the Illinois public-safety community allowing for a
graceful migration to narrow-band for common interoperability
channels such as IREACH, ISPERN, MERCI, UHF-Med Channels, IFERN, WB
Fireground Channels, ESMARN, and Point-to-Point. Reminder from the MABAS Telecommunications and Dispatch Committee On January 1, 2013, all public safety and business industrial land mobile radio systems operating in the 150-512 MHz radio bands must cease operating using 25 kHz efficiency technology, and begin operating using at least 12.5 kHz efficiency technology. This deadline is the result of an FCC effort that began almost two decades ago to ensure more efficient use of the spectrum and greater spectrum access for public safety and non-public safety users. Migration to 12.5 kHz efficiency technology (once referred to as Refarming, but now referred to as Narrowbanding) will allow the creation of additional channel capacity within the same radio spectrum, and support more users. After January 1, 2013, licensees not operating at 12.5 KHz efficiency will be in violation of the Commission's rules and could be subject to FCC enforcement action, which may include admonishment, monetary fines, or loss of license. Each MABAS Division received a copy of the Il-APCO DVD Presentation regarding the FCC mandated narrow banding requirements at this years MABAS conference. Please refer to that presentation and begin planning now if you have not already done so. Additionally, for those departments that received a VHF interoperable radio from the ITTF remember to include that radio in your narrow banding plan. Further information can be obtained from the FCC website; www.fcc.gov
NPSTC
reached out to the federal government to seek information about
funding alternatives in support of narrowbanding and received the

For those
inquisitive folks who may be interested in learning more about the
history and background of the FCC's narrowbanding proceeding and the
resulting mandate (and, who happen to have a fair amount of time on
their hands!)......
Happy reading!

A Historical
Record of the FCC's Part 90 Narrowbanding Proceeding
Basically,
narrowbanding all started with and FCC Notice of Inquiry
(91-170) in
July of 1991. A record of the filers in that proceeding
is available here:
http://fjallfoss.fcc.gov/ecfs2/document/view?id=6005043895
I haven't
been able to locate an archived copy of the actual Notice
of Inquiry;
however, the NOI was followed up by a Notice of Proposed
Rulemaking
(PR Docket 92-235) released in November of 1992:
http://fjallfoss.fcc.gov/ecfs2/comment/view?id=107799
The first 75
or so pages contain most of the meat and potatoes
related to
this proceeding....i.e. remember Part 88? How about the
consolidation
of all radio services to just two? Centralized
trunking?
Spectrum efficiency standards?
which
eventually led to the current narrowbanding proceeding known
as WT Docket 99-87:
http://fjallfoss.fcc.gov/ecfs2/proceeding/view?name=99-87
As those who
follow the above links will discover, the new and
improved FCC
ECFS 2 (Electronic Comment Filing System) really is...
Much of the
information now available has never been easily found
or accessible
to the the general public prior to now.
