In the Fall of 2006, a couple of U.S. fire departments discovered that the voice audio from digital radios in the presence of background noises (common to the fire operations) may cause distortion to the degree of becoming unintelligible.
These Departments after not being able to get resolution to the problem or identify the cause other than it being in digital radios notified the IAFC, and the IAFF.
March 20, 2007, the IAFC issued a Member Alert.
The IAFC also approved the formation of a Working Group to determine the scope of the problem and work with manufacturers and other stakeholders to identify and/or develop short and long term solutions.
On May 8, 2007, the Working Group convened and established two sub groups (Testing and Best Practices).
The Testing Group is focused on more long term solutions while the Best Practices Group is focused on quicker solutions through behavior and/or operational modifications.
Includes things such as microphone placement and specific issues that should be addressed in training.
Developed a PowerPoint presentation for educational and outreach purposesBest Practices
9 noise conditions
With and without mask, noises like fire trucks, chain saws, low air alarms, PASS alarms
4 radio systems
25 KHz analog, 12.5 kHz analog, baseline P25, P25 with enhanced vocoder
54,000 sample files generatedTesting Group
Radio communications are essential for successful Public Safety operations
Interoperability is vital
Interference poses a significant threat to successful communications and to the safety of life of public safety responders
Borders should be transparent for public safety operations
Interference must be eliminated quickly
Note: Canada and Mexico present different challenges
150 – 174 MHz
450 – 470 MHz
470 – 512 MHz
800 MHz (including NPSPAC)
4.9 GHz wideband
NPSTC supports the HLCC and its Directory of Bilateral Issues for 2007-2009
Protocols for VHF/UHF spectrum use
Reconfiguration of 800 MHz band
700 MHz compatibility
Interference resolution procedures
NPSTC supports the cross-border microwave network solution for PS interoperability
Further issues for consideration
TV channel 15 vacated in Mexico and should be considered for Public Safety use
Adoption of common nomenclature for public safety communications across the border
700/800 MHz progressing
Above 30 MHz Agreement needs revision
Too many US applications being denied
No common interference standards
No protocol for interference resolution
No 4.9 GHz agreement
NPSTC working directly with sister PS organization in Canada on common issues (under guidance of DOS and FCC)
Resolution of border issues is essential for national security
Seamless interoperability across borders
Several additional bilateral agreements to share or coordinate use of spectrum are needed
In the new agreements spectrum should be distributed equitably and procedures for coordination streamlined
Interference resolution procedures similar to those used with Mexico are needed for Canada
Naming structure: Btype##M
B Band L,V,U,7,8
Type CALL, DATA, FIRE, GTAC, LAW, MED, MOB, TAC
## A unique number from 01-99 that also identifies the band
