What is the maximum acceptable field strength for leakage limits set by the FCC?

The maximum acceptable field strength for leakage limits set by the FCC for devices operating in certain frequency ranges is indeed 15 µV/m at 30 meters for frequencies above 216 MHz. This regulation is in place to ensure that any emissions from the devices do not interfere with licensed services and to protect the integrity of communications systems.

The choice of 15 µV/m at 30 meters specifically targets higher frequency operations, which are more sensitive to interference. The specified measurement distance of 30 meters is standard for assessing leakage from various RF devices, allowing for a consistent method of regulation enforcement. This limit is critical in maintaining the quality and reliability of communication networks, especially in environments where many devices operate simultaneously.

In contrast, the other measurements provided either apply to different conditions or are not in alignment with the FCC's regulations on leakage limits for the specified frequency range. By adhering to the established maximum levels, technicians can help ensure compliance and minimize potential disruptions to other services.
