47 CFR FCC Part 15 Subpart F Ultra-Wideband Operations Testing
FCC subpart F of the 47 CFR testing standard describes unlicensed ultra-wideband transmission systems. 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 is continually developing partnerships in GMA and RF exposure testing. These strategic partnerships allow us to meet customer needs beyond our scope of accreditation. Our RF testing engineers provide the peace of mind that all of your wireless testing needs will be met.

Summary of Subpart F Wideband Operation Testing
The FCC standard test method specifically sets out regulations for unlicensed ultra-wideband (UWB) transmission systems. UWB bandwidth is described as the frequency band bounded by the points that are 10 dB below the highest radiated emission. Furthermore, this is only based on the complete transmission system including the antenna.
The requirements of this wireless FCC subpart only apply to the radio transmitter. I.e. the intentional radiator, contained in the UWB device. Other aspects of the wireless intentional device are subjected to conditions within other parts of the FCC test.
Scope of 47 CFR FCC Ultra-Wideband Wireless Lab Testing
In some cases, the operation of a UWB device is strictly for specified parties. These include law enforcement, and fire and rescue organizations. Marketing of a device used in any other manner can lead to revocation of the grant certified to the issued equipment.
Operating under the specified provisions in subpart F is limited to ground-penetrating radars and wall imaging systems. These systems are operated for the purpose associated with law enforcement, fire fighting, emergency rescue, scientific research, commercial mining, or construction.
The UWB bandwidth of an imaging system must be below 960 MHz or the center frequency. The frequency at which the highest radiated emission occurs must be contained between 1990 MHz and 10600 MHz.
Subpart F also clarifies the technical requirements of other wireless systems. As an accredited ISO 17025 lab, Keystone can assist in the compliance of any systems mentioned below.
- Ground-penetrating radars and wall imaging systems
- D-wall imaging systems
- Surveillance systems
- Medical imaging systems
- Vehicular radar systems
- Indoor UWB systems
- Handheld UWB systems
