The FCC's Table of Frequency Allocations consists of the International Table of Frequency Allocations ("International Table") and the United States Table of Frequency Allocations ("United States Table"). The FCC's Table of Frequency Allocations is codified at Section 2.106 of the Commission's Rules.
For the allocation of frequencies the ITU has divided the world into three Regions. Click here to view a PDF map of the three Regions.
The general rules for reading the Table are:
- Primary services are printed in "capitals;" e.g., FIXED.
Secondary services are printed in "sentence case or normal characters;" e.g., Mobile. Stations of a secondary service:
- Shall not cause harmful interference to stations of primary services to which frequencies are already assigned or to which frequencies may be assigned at a later date;
- Cannot claim protection from harmful interference from stations of a primary service to which frequencies are already assigned or may be assigned at a later date; and
- Can claim protection, however, from harmful interference from stations of the same or other secondary service(s) to which frequencies may be assigned at a later date.
Additional information about the FCC's table of frequency allocation is available in the Commission's rules. Section 2.104 provides information about the International Table while Section 2.105 contains information regarding the US Table of Frequency Allocations. The table itself is located in Section 2.106 (this link is for informational purposes only). The Commission regularly updates its Online Table of Frequency Allocations shortly after a final rule has been released. Download the FCC Online Table [Word | PDF] .
