If you own or operate a radio communications system then you must follow the Federal Communications Commission Rules and Regulations.
Failure to do so could result in fines, forfeitures, or imprisonment.
Public Safety and Public Service operate under FCC Rules and Regulations, Part 90 primarily.
Rule Number 1
![Page 4: Public Safety Communications](https://reader036.vdocuments.us/reader036/viewer/2022062519/56814f91550346895dbd4ad3/html5/thumbnails/4.jpg)
So what does that mean to me?
You must have a valid FCC license. Exception - Police surveillance, 2 watts or less, approved
by frequency coordinator Exception - You use a radio system owned and operated
by another public safety agency or commercial vendor.
![Page 5: Public Safety Communications](https://reader036.vdocuments.us/reader036/viewer/2022062519/56814f91550346895dbd4ad3/html5/thumbnails/5.jpg)
What does my agency need to do?
You should have obtained an FCC Registration Number (FRN) using your Federal Taxpayer ID #.
Registered all your FCC Callsign(s) with the FCC using your FCC Registration Number (FRN)
![Page 6: Public Safety Communications](https://reader036.vdocuments.us/reader036/viewer/2022062519/56814f91550346895dbd4ad3/html5/thumbnails/6.jpg)
Rule Number 2
Never, ever let your license expire
Renewal of your FCC license, without technical changes, costs nothing and can easily accomplished over the internet. Minor changes may be made over the internet such as phone #, contact person, etc.
Once your license expires, your frequency is up for grabs.
Once your license expires, then you have to pay the frequency coordination fees.
![Page 7: Public Safety Communications](https://reader036.vdocuments.us/reader036/viewer/2022062519/56814f91550346895dbd4ad3/html5/thumbnails/7.jpg)
Licenses are now good for ten years. Impact - More chance for licenses to get
lost when renewal time comes up. I recommend that you not use a persons’
name but the department section.

Rule Number 3
If you move your radio site, dispatch office, increase the antenna height, increase power, etc., you need to file a license modification. Keep your license current.
![Page 9: Public Safety Communications](https://reader036.vdocuments.us/reader036/viewer/2022062519/56814f91550346895dbd4ad3/html5/thumbnails/9.jpg)
Other rules to know
You need to use your FCC Callsign or have it automatically transmitted. (90.425)
The FCC requires periodic radio equipment checks (90.215)
Post your FCC license at the transmitter site (90.437)

Simplex SystemClass Station: FBBase and Mobile take turn to communicate.Base & Mobile utilize one frequency such as 155.1300 MHz.
![Page 13: Public Safety Communications](https://reader036.vdocuments.us/reader036/viewer/2022062519/56814f91550346895dbd4ad3/html5/thumbnails/13.jpg)

REPEATER SYSTEM
Class Station: FB2 Base & Mobile Communicate at the same
time. The base transmits on 153.1300 & receives
on 158.1300 MHz. The mobile transmits on 158.1300 &
receives on 153.1300 MHz.

Repeater System
Base can reach the mobile due to tower height, output power, and high ERP.
Mobile is too far away from the base to communicate back (referred to as Talk-Back or Talk-IN).
Solution: USE OF A SATELLITE RECEIVER

Mutual Aid and Interoperability Frequencies
Wikipedia, the free on-line encyclopedia defines “Mutual Aid” as
In emergency services, mutual aid is a formal agreement among emergency responders to lend assistance across jurisdictional boundaries when required; either by an emergency that exceeds local resources or a disaster. Alabama has agreements to share certain frequencies.
“Interoperability” is defined as the ability of two or more systems or components to exchange information and to use the information that has been exchanged. The FCC designated five VHF frequencies and four UHF frequency pairs for Interoperability across the nation.

NPSPAC 800 MHz Region 1
In 1988, the FCC allocated additional 800 MHz spectrum to Public Safety if they would form Regional Planning Committees and set
policies and standards on how the spectrum would be utilized.
The Alabama Region 1 Plan was developed and approved by the FCC.
All counties in Alabama has been allocated at least four frequency pairs.
Five dedicated National Interoperability frequency pairs

Firm TV clearing date of 02/17/09.
Up to $1B for interoperable communications equipment for public safety

Interference
All radio systems will have interference from time to time due to weather, band openings, or another system 50 or more miles away
“Harmful Interference” is what the FCC will investigate
Nuisance Interference is not necessarily “Harmful”.
To register an interference complaint:
Contact the FCC or APCO

Refarming (Narrowbanding)
All existing Part 90 radio systems operating on frequencies between 150-512 MHz have until January 1, 2013 to convert those systems to 12.5kHz bandwidth.
Impact - To try to make more frequencies available by splitting the frequencies in half.

FCC Radio License Audit
FCC has sent an audit letter to all FCC License holders under 512 MHz to see what spectrum
can be reused.
Began September 1, 2001
You had 60 days to respond
