CWS Regulatory Compliance & Legal Framework 3 — Questions and Answers
Question 1: Under the FCC's rules for the 6 GHz band (U-NII-5 through U-NII-8), which category of devices is permitted to operate at the highest power levels indoors?
- Standard Power Access Points with AFC coordination (Correct answer)
- Low Power Indoor (LPI) devices
- Very Low Power (VLP) devices
- Fixed outdoor point-to-point links only
Correct answer: Standard Power Access Points with AFC coordination
Standard Power devices in the 6 GHz band may operate at higher EIRP levels (up to 36 dBm) but must use Automated Frequency Coordination (AFC) to protect incumbent licensed users.
Question 2: The CE mark on a wireless product sold in Europe indicates what from a regulatory standpoint?
- The product conforms to applicable EU directives including the Radio Equipment Directive (RED) (Correct answer)
- The product has passed FCC Part 15 testing
- The product is certified by a specific European testing laboratory only
- The product meets only the EU's minimum safety voltage requirements
Correct answer: The product conforms to applicable EU directives including the Radio Equipment Directive (RED)
The CE mark signifies that a product meets all applicable EU directives, with wireless products specifically needing to comply with the Radio Equipment Directive (RED 2014/53/EU).
Question 3: In the context of wireless networking, what is a 'frequency coordination' study used to determine?
- Whether a proposed wireless system will cause or receive harmful interference with existing licensed systems (Correct answer)
- The optimal Wi-Fi channel plan for an enterprise building
- The number of access points needed for full coverage
- Whether a device complies with FCC Part 15 emission limits
Correct answer: Whether a proposed wireless system will cause or receive harmful interference with existing licensed systems
Frequency coordination studies analyze proposed wireless deployments against databases of existing licensed systems to identify and mitigate potential interference conflicts.
Question 4: Which regulation requires that wireless devices sold in the US include the statement that the device may not cause harmful interference and must accept any interference received?
- FCC Part 15 compliance statement (Correct answer)
- HIPAA wireless security clause
- NEBS Level 3 certification requirement
- FCC Part 68 registration statement
Correct answer: FCC Part 15 compliance statement
FCC Part 15 requires that unlicensed devices include a compliance statement acknowledging both non-interference and interference-acceptance obligations.
Question 5: A hospital in the US wants to deploy a wireless nurse call system. Which additional regulatory consideration beyond FCC Part 15 is most relevant?
- FDA regulations if the system qualifies as a medical device or is used for patient monitoring (Correct answer)
- EPA emissions standards for electronic equipment
- FCC Part 22 public mobile service licensing
- OSHA RF exposure limits for hospital staff only
Correct answer: FDA regulations if the system qualifies as a medical device or is used for patient monitoring
Wireless medical devices or systems used in patient care may fall under FDA jurisdiction as medical devices, requiring additional regulatory compliance beyond FCC radio authorization.
Question 6: What is the primary purpose of the Spectrum Act provisions in the Middle Class Tax Relief and Job Creation Act of 2012 in the US?
- To authorize voluntary spectrum incentive auctions allowing broadcasters to relinquish spectrum for reallocation to mobile broadband (Correct answer)
- To create the FCC's Part 15 unlicensed device rules
- To mandate Wi-Fi in all federal buildings
- To establish the CBRS band for commercial use
Correct answer: To authorize voluntary spectrum incentive auctions allowing broadcasters to relinquish spectrum for reallocation to mobile broadband
The Spectrum Act authorized spectrum incentive auctions where TV broadcasters could voluntarily give up spectrum, which was then repurposed for mobile broadband (the 600 MHz band).
Question 7: An enterprise network engineer discovers that a vendor's access point is transmitting on a 5 GHz DFS channel without first performing a Channel Availability Check (CAC). What is the regulatory implication?
- The device is violating FCC rules, as a minimum 60-second CAC is required before transmitting on DFS channels (Correct answer)
- DFS channels only require CAC in outdoor deployments, so this is acceptable indoors
- CAC is optional if the AP uses MIMO technology
- The FCC only requires CAC for devices with more than 100 mW transmit power
Correct answer: The device is violating FCC rules, as a minimum 60-second CAC is required before transmitting on DFS channels
FCC rules mandate a minimum 60-second Channel Availability Check on DFS channels to detect radar before initiating transmissions, regardless of deployment environment.
