  1. Public Safety Communications Radio 101

  2. Presented By Eric Linsley Director of Public Safety Communications Mobile County Commission APCO Local Frequency Advisor Region 1 700 MHz Chairman Region 1 800 MHz NPSPAC Vice-Chair Credit given to John Johnson TN Emergency Management Agency

  3. Rule Number 1 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.

  4. 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.

  5. 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)

  6. 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.

  7. 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.

  8. 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.

  9. 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)

  10. Tower Owners • Tower Registration • RF Exposure Regulations • Lighting and Marking

  11. Base/Mobile System Configurations

  12. Simplex SystemClass Station: FBBase and Mobile take turn to communicate.Base & Mobile utilize one frequency such as 155.1300 MHz.

  13. SIMPLEX SYSTEM Tx=Rx=155.1300 MHz for Mobile & Base

  14. 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.

  15. Repeater System Tx = 153.1300 MHz Rx = 158.1300 MHz

  16. Repeater System 153.1300 158.1300 158.1300

  17. 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

  18. Satellite Receiver Configuration 158.1300 153.1300 Satellite Receiver Landline or Microwave

  19. 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.

  20. Alabama Statewide Mutual Aid Frequencies All are simplex operation with no PL tones. All are wideband operation: Display Name Frequency (MHz) Purpose_______________________________________ MA LE 155.010 Alabama State Law Enforcement Mutual Aid. Also known as Inner City. MA FIRE 155.040 Alabama State Fire Mutual Aid MA AMBL 155.265 Alabama State Ambulance Mutual Aid N E L E 155.475 National Law Enforcement N FIRE 154.280 National Fire N EMS 155.340 National EMS. Alabama Hospitals have this for their use.

  32. 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

  33. 800 MHz Interoperability Frequencies 821/866.0125 ICALL 821/866.5125 ITAC 1 822/867.0125 ITAC 2 822/867.5125 ITAC 3 823/868.0125 ITAC 4 Simplex or Repeater operation

  34. 700 MHz Regional Planning • FCC Report and Order 96-86 • FCC has reallocated 60 MHz of spectrum from TV channels 60 – 69. • 36 MHz allocated for Commercial wireless usage. • 24 MHz allocated for Public Safety usage. • President Bush signed the date certain DTV transition legislation on Feb 8,2006. Part of S.1932, Deficit Reduction Act of 2005. Law provides for: • Firm TV clearing date of 02/17/09. • Up to $1B for interoperable communicationsequipment for public safety

  35. 700 MHz Public Safety Band 24 MHz allocated to Public Safety - Channels 63 - 64 & 68 - 69 12.6 MHz will be for Public Safety general use 2.6 MHz for Interoperability / Mutual Aid 2.4 MHz for State agencies 8.8 MHz will be held in reserve for future technology growth. Region 1 Alabama submitted our plan on September 11, 2006. Still pending F.C.C. review.

  36. 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

  37. 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.

  38. 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 http://wireless.fcc.gov/plmrs/audit.html
