Frequency Coordination

Carolina Microwave Associates, Inc. performs a wide range of frequency coordination and licensing services for industrial radio users. In addition, to frequency coordination, Carolina Microwave Associates, Inc. services include:

  • Contour analysis (including impact of new applications on existing radio systems Form 601 preparation and Schedule K (required notification) filing
  • Co- and adjacent-channel analysis for 72, 150, 450, 800 and 900 MHz systems
  • Preparation of FCC Registration (CORES) filings
  • Assistance with short-spacing consent letters

Before we begin the journey, we will need the following basic information from you:

  • Frequency / Frequency Band
    • What frequency band or specific frequency you want to operate on.
  • Mobile Radio Count
    • The number of mobile radios that will operate on the system.
  • Output Power / ERP Tx
    • The output power of the system amplifier, as well as the effective radiated power (ERP), which is the system's power at the antenna.
  •     Emmision Designators
    • Includes several pieces of vital information: modulation, signal, type of information and size of the channel. This determines the channel width your system will occupy.
  •     Antenna Information
    • You must also provide the following information about your antenna. The most common codes are:
      •     B - Building with side mounted antenna
      •     BANT - Building with antenna on top
      •     MAST - Self-supported structure    
      • PIPE - Pipe antenna
      •     POLE - Any type of pole antenna
      •     TOWER - Free standing guyed structure used for communications purposes
  •     Height
    • Antenna height from ground to tip, in meters
  •     Support Structure Height
    • If antenna is mounted on top of a building, it is the distance from ground to the top of the building. Check with your building management company for this information.
  •     Coordinates
    •         All coordinates (latitude/longitude) must be referenced to the North American Datum of 1983 (NAD83). Latitude and longitude must be listed in degrees, minutes and seconds.
  •     Site Elevation
    • The antenna site ground elevation above sea level. This information should always be in meters.
  •     FAA Antenna Structure Registration
    •   Refer to ASR TOWAIR Determination to determine if your antenna needs to be registered with the FCC.
