  1. What is the minimum channel availability check (CAC) time required before a Wi-Fi device can transmit on a DFS channel?

    Answer: 60 seconds

    FCC rules require a 60-second Channel Availability Check before an 802.11 device begins transmitting on a DFS channel.

  2. An enterprise is importing Wi-Fi access points from a foreign manufacturer. Which mark must US-bound units carry before sale?

    Answer: FCC ID label

    Radio devices sold in the US must display an FCC ID, issued after the device has been authorized through the equipment authorization process.

  3. Under FCC Part 15.407, low-power indoor (LPI) devices in the 6 GHz band are restricted to what maximum EIRP?

    Answer: 30 dBm (1 W)

    FCC Part 15.407 permits LPI 6 GHz devices up to 30 dBm EIRP when operating indoors without automated frequency coordination.

  4. What is the purpose of Automated Frequency Coordination (AFC) for standard power devices in the 6 GHz band?

    Answer: Ensure standard power devices do not interfere with fixed microwave and satellite incumbents

    AFC systems query a geospatial database to determine which 6 GHz channels and power levels are safe for standard power outdoor devices near licensed incumbents.

  5. Which regulatory document defines how Wi-Fi equipment must be tested to verify compliance with FCC limits?

    Answer: KDB (Knowledge Database) publication procedures

    The FCC's Knowledge Database (KDB) provides detailed test procedures and Q&A guidance that equipment must follow to receive FCC authorization.

  6. A wireless network causes interference to a neighbor's licensed microwave link. Under FCC rules, who bears the primary responsibility to resolve the interference?

    Answer: The unlicensed Part 15 operator must cease operation or fix the interference

    FCC Part 15 explicitly states that unlicensed devices must accept harmful interference and must not cause harmful interference to licensed services.

  7. Which Wi-Fi Alliance certification program validates interoperability and security compliance for 802.11ax devices?

    Answer: Wi-Fi CERTIFIED 6

    Wi-Fi CERTIFIED 6 (and 6E/6 GHz variants) is the Wi-Fi Alliance's interoperability certification for 802.11ax devices.
