2.2.1 FCC Emission Designators: How to Find Them
An FCC emission designator is a seven-character string that represents the bandwidth, modulation, and
other characteristics of a transmitted radio signal. This information is required when applying for an FCC
license. The designator assigned to your equipment depends on the particular sub-model of the product
line you are licensing. In some cases, multiple designators are used to cover product variants such as base
