47 CFR FCC Part 2 Certification Testing of Radio Frequency Devices
The FCC standard describes the testing and marketing of radiofrequency devices. As a leader in RF regulatory compliance testing, Keystone Compliance recognizes the requirements needed for wireless radio manufacturers. Meeting the ETSI, FCC, and other wireless testing specifications can be challenging. Not only do we understand the challenges, but we help guide companies through the process.
Keystone Compliance’s accurate test reports are delivered quickly using our “four-eyes” approach. Meaning that multiple technicians review each report, ensuring that all the information required is present. Our radio testing engineers streamline the process and assist companies to achieve the compliance they require.

Summary of FCC Frequency Allocations and Radio Testing
Part 2 of the wireless FCC standard describes the radio spectrum and frequency bands concerning the marketing of devices. A radio frequency (RF) device in which operations are capable of emitting radio frequency energy by radiation, conduction, or other means. RF devices include:
- Various types of radio communication transmitting devices
- Incidental, unintentional, and intentional radiators
- Industrial, scientific, and medical equipment
- Any part or component thereof which in use emits radiofrequency energy by radiation, conduction, or other means
Equipment authorization procedures are conducted to promote safe and efficient use of the radio spectrum. In addition to the technical standards provided, equipment may require authorization from the Supplier’s Declaration of Conformity. The equipment may also need to receive a grant of certification from a Telecommunication Certification Body.
It is generally unacceptable to market a radiofrequency device. Before marketing, the equipment must be authorized by various conformance regulations, a compliance facility, and the FCC. Furthermore, an RF device may not be operated before equipment authorization unless specified conditions are met.
The radio spectrum is subdivided into nine frequency bands. As the unit of frequency is the hertz, frequencies are expressed in kilohertz, megahertz, and gigahertz. These frequencies are included from the range of 3 hertz up to 3,000 hertz.
Scope of FCC Part 2 Radio Frequency Device Testing
The FCC may allow federal stations to use non-federal frequencies in the bands above 25 MHz. Operations being performed must be following specified Commission rules. These operations can not cause harmful interference to non-federal stations.
Emissions are designated according to their classification and necessary bandwidth. Furthermore, the basic characteristics of emissions can be classified according to the following:
- Type of modulation of the main carrier
- Nature of signal(s) modulating the main carrier
- Type of information to be transmitted
Non-Federal stations are authorized to use Federal frequencies in the bands above 25 MHz. Non-Federal stations must also understand that the 25 – 50 MHz frequency is shared with various services of other countries. Harmful interferences are caused by skywave signals received from different stations on frequencies of this band. If harmful interferences arise, the operation is immediately terminated.
Aircraft stations may communicate with stations of the maritime mobile service. These stations must conform to international radio regulations.
A grant of certification is only valid when the device is labeled by the information stated above. The grant remains until the device is revoked, withdrawn, or a termination date is established by the FCC. This grant recognizes that the equipment is compliant with the applicable technical standards set by the FCC.
