- Now
comes still another group, the "800 MHz Users Group," with
what it calls a "balanced approach" to reducing inteference
in the band. The group's filing with the FCC said, "This
proposal is believed to be much less expensive, less burdensome and
far more in alignment with the Commission's spectrum policies than
the Private Wireless Coalition plan now before the Commission."

- APCO's Automated Frequency Coordination group has
published their latest newsletter, with information on a fee
increase, 800 MHz rebanding, and a fee agreement reached by APCO and
the three other frequency coordinator groups. Download an Acrobat

9/19/02
- (From DispatchMonthly.com) The FCC is asking for
comments on whether it should modify the existing frequency
coordination procedures for the Public Safety Pool below 470 MHz, by
allowing competition among the current coordinators, an action
prompted by a Feb. 2002 APCO petition. The FCC now authorizes four
coordinators, each with an exclusive number of frequencies to handle:
APCO (455), the IAFC and IMSA (305), the American Association of
State Highway Transportation Officials (98), and the Forestry
Conservation Communications Association (131). APCO argues the change
would streamline the coordination process, introduce competition
among coordinators, and reduce costs for applicants. The other three
coordinators oppose the move, saying--among other things--that a
competitive coordination approach could result in errors and
coordination interference, which could jeopardize lives and property. |
|
What is
frequency coordination? |
|
It is required by the FCC before an
application is submitted to them for frequencies. Another
company, such as APCO, researches the frequency you've chosen, or
finds one for you, so that it will not interfere with nearby
agencies/businesses. They will also file the application
for you, taking care of the emission designators and all appropriate
information. Agencies can also request a
"Concurrance" for use of a frequency by another nearby agency. |

Interoperability Channels |
|
Use of the following frequencies
must be compliant with FCC limitations (80) (&ldots;this frequency is
available primarily for public safety interoperability only
communications&ldots;) and limitation (27) (narrow band emission
only). An eligible entity must have a license to operate
a base or control station on these channels. Public safety
licensees who are eligible to hold a Part 90 license, or who are
otherwise licensed under Part 90, can operate mobile units on these
channels without an individual license.
nteroperability channels as
designated by the FCC, are by definition intended to be used for
“two or more different entities to interact with one another and
to exchange information&ldots;” (FCC 90.7 -Definitions for
“Interoperability”). So frequency coordination is not
really necessary.
The Third MO&O states,
"Prior to January 1, 2005, interoperability use will be
permitted only on a secondary basis to existing users; that is,
interoperability transmissions can be made only when the channel is
clear and on a non-interference basis." Particularly
related to use as base or control stations licensed on these
channels, the FCC will license interoperability use on these
channels, the FCC anticipates a condition on any such license making interoperability
communications secondary to the
existing licensees until January 1, 2005. Incumbent operations
licensed and operating on these frequencies prior to December 7, 2000
in non-interoperability manners are consider to be co-primary until
January 1, 2005 at which time they will become secondary to any
interoperability operations.

ISR -
IntraSquad Radio |
|
Due to the recent proliferation of
FRS all over the place, many federal government spectrum users were
eyeballing FRS as a way to augment some communications where they
need something quick and dirty, and are not worried about
security. The problem with this is that FRS is an FCC-regulated
communications service, and federal spectrum users are not under FCC
regulation, rather the NTIA. A federal spectrum user
cannot use FCC spectrum "at will" - it is seen as
encroachment. However, there are special cases where MOU,
etc, can exist so that a federal spectrum user can come up on an FCC
frequency (such as Metro Fugitive Squad, etc).
But in case, DOD users wanted to
have an "FRS" service of their own. Hence, ISR was
born - intra-squad radio. This is 14 channels on a shared basis
in the federal areas - any DOD spectrum user can basically use it.
The 14 channels assigned are:
01) 396.875 MHz
02) 397.125 MHz
03) 397.175 MHz
04) 397.375 MHz

Federal
Government Spectrum Available for
Public Safety - Interoperability Communications |
|
The purpose of
this Public Notice is to remind
the public safety community that
the National Telecommunications and
Information Administration (NTIA) has
specified forty (40)
Federal Government frequencies that
can be used by non- Federal
government public safety entities (see 47
C. F. R.
§ 90. 20 for eligibility
criteria) for communications involving
coordination and cooperation with Federal
Government agencies. 1 These
frequencies may not be used to
meet the day- to-
day communications needs of non-
Federal government public safety
entities. Due to previous
frequency
authorizations to Federal Government
agencies, not all channels will be
available at all locations. The
specific frequencies available are
listed in the attached Appendix.
The rules governing the use of
these frequencies (power, bandwidth,
etc.) are set forth in Section
4.3.16 of
the NTIA
Manual (Manual of Regulations and
Procedures for Federal Radio
Frequency Management – see
NTIA’s web page at www. ntia.
doc. gov/ osmhome/ redbook/ redbook. html).
In order for
non- Federal public safety entities
to use these frequencies they must
obtain a license from the Federal
Communications Commission (FCC). License
applications must contain
written certification from a Federal
Government agency that use of the
requested frequency or frequencies is
necessary to improve interoperability
communications between the applicant and
the Federal Government agency during
emergencies. Frequency coordination with
a FCC- certified frequency coordinator
is not required for these
frequencies. The FCC will submit
all applications received for these
frequencies to NTIA’s Interdepartment
Radio Advisory Committee's
Frequency Assignment Subcommittee for
approval. Operation on the frequencies
is not permitted until a
FCC license is granted. Once a
license is granted, the licensee
must provide a copy of the
license to the Federal Government
agency or agencies with which it
will be communicating.
For further
information about FCC licensing, contact
the ULS Hotline at 1- 888-
225- 5322 and select Option 2
from the menu. For more
information about NTIA’s interoperability
frequencies, contact the NTIA Office
of Spectrum Management’s Frequency
Assignment Branch at 202- 482- 1132
or the Public Safety Program
Office at 202- 501- 5487.
1 These
frequencies are available for public
safety use under Sections 2.102(
c) and 90.173( c) of the Rules
(see 47 C. F. R. §§
2. 102( c) and 90.173( c)). 1

Emergency
Locator Trasmitters (ELT) on 406.025 |
|
10/14/02 -
From DispatchMonthly.com
- The FCC has ruled to allow personal use of emergency locator
transmitters (ELT) on 406.025 MHz, which was previously limited to
marine or aviation purposes. The devices' signal is received by
satellites and relayed by NOAA to either the Coast Guard (marine) or
Air Force (land) for rescue coordination. The commission requires
registration of purchased devices with NOAA, ruled that false alarms
won't be a problem, and decided that the USAF will handle alerts
initially, and farm them out to state-identified control points for
dispatch to local or county agencies to handle. The high cost, size
and regulation of the devices will limit their distribution, but keep
you eye peeled for this new type of emergency reporting device. |

4/03 - Radio manufacturer EFJ Inc.
introduced their Tactical Interoperability Kit, which mates radios on
