47 CFR FCC Part 15 Subpart C Intentional Radiators Testing

Intentional radiators are devices that generate radio frequency energy intentionally during the equipment operation. Radiofrequency energy can be emitted by either radiation or induction. 

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. 

From concept through compliance, Keystone meets all of our customers’ needs under one roof. Our proven process helps avoid product launch delays by inviting our clients to review draft reports before final certification. Additionally, we are in constant communication throughout the entire test process.

Summary of CFR Part 15C Intentional Radiator Wireless Testing

All intentional radiators, unless otherwise exempt, must be certified by the FCC. Some devices are required to be measured at the installation site. Furthermore, each application must show proof of compliance. The device must also be accompanied by a statement indicating that the system has been tested and complies with three installations.

The holder of the grant certification will test each installation before normal operation. This verifies compliance with the technical FCC standard. For perimeter systems operating outside the television frequency bands, further testing is needed upon receipt of a grant certification.

Scope of 47 CFR Subpart C Wireless Test

Devices that operate in a master/client network are generally certified if they can operate beyond the part 15C scope under the control of the master device. A master device operates in a mode in which it can transmit without receiving an enabling signal.

The intentional radiator is designed to ensure that no antenna other than its own will be used with the device. A permanently attached or unique coupling antenna is sufficient for the compliance of this wireless standard. However, the 47 CFR FCC 15C antenna requirement does not apply to intentional radiators that need to be professionally installed.

Conditions of FCC Intentional Radiator Wireless Devices

Conducted limits are intended to be connected to the public utility power lines. If this is true, they can not exceed specified limits within the standard. The quasi-peak limits range from 66 to 56 while the average limits are from 56 to 46.

Compliance is based on the radio frequency voltage between each power line and ground at the power terminal. Measurements to demonstrate compliance with the conducted limits is generally not required. However, this is only for devices that use battery power for operation. The devices must also not operate from AC power lines
