Regulatory Frameworks & Compliance Flashcards

Which FCC rule part specifically governs unlicensed intentional radiators operating in the ISM bands?

Answer: Part 15

FCC Part 15 covers unlicensed intentional radiators, including Wi-Fi devices operating in ISM bands.

What is the maximum EIRP allowed for point-to-point 5 GHz UNII-1 outdoor links when using a directional antenna?

Answer: 1 W (30 dBm)

UNII-1 (5.15–5.25 GHz) is restricted to indoor use with a maximum of 50 mW EIRP unless a waiver is granted; point-to-point outdoor use requires UNII-3.

In the EU, which regulatory body sets the framework that member states must implement for radio equipment?

Answer: ETSI

ETSI produces the harmonized standards that give legal presumption of conformity under the EU Radio Equipment Directive (RED).

A CWNA candidate is deploying a 2.4 GHz system in Canada. Which body's standards must the equipment comply with?

Answer: Innovation, Science and Economic Development Canada (ISED)

ISED Canada (formerly Industry Canada) is the national authority that certifies radio equipment and sets spectrum rules in Canada.

What does the term 'spurious emissions' refer to in FCC regulations?

Answer: Emissions at frequencies outside the necessary bandwidth that are not harmonics

Spurious emissions are unintended transmissions at frequencies other than the carrier and its harmonics, regulated to prevent interference.

Which UNII band was opened by the FCC in 2020 to provide an additional 1,200 MHz of unlicensed spectrum?

Answer: UNII-5 through UNII-8 (6 GHz)

The FCC's 2020 Report and Order opened the entire 6 GHz band (5.925–7.125 GHz), divided into UNII-5 through UNII-8, for unlicensed use.

What is the primary purpose of DFS (Dynamic Frequency Selection) as required by FCC rules?

Answer: Avoid interference with radar systems by detecting and vacating radar frequencies

DFS is mandatory in UNII-2 and UNII-2C to detect active radar and move to a clear channel within 10 seconds.
