✍️ Sample CWDP Questions & Answers
1. Which IEEE amendment defines fast BSS transition (FT), reducing roaming latency for real-time applications?
IEEE 802.11r defines Fast BSS Transition, enabling pre-authentication with target APs to reduce handoff time below 50 ms.
2. A CWDP designer is planning for 20 simultaneous VoIP calls per AP. What minimum data rate should be supported per call (G.711 codec)?
G.711 at 64 kbps payload plus RTP/UDP/IP/802.11 headers totals approximately 87.2 kbps per call.
3. Which US regulatory body governs maximum transmit power levels and permitted channels for WLAN deployments?
The FCC sets the legal limits for transmit power, antenna gain, and permitted channels for unlicensed spectrum used by WLAN in the United States.
4. What information should be gathered during a pre-survey site visit?
A thorough pre-survey visit documents construction materials (wall composition, glass types), ceiling types and heights, existing cabling and mounting points, potential RF interference sources, aesthetic requirements, and client needs.
5. What factor most significantly increases free-space path loss between two outdoor wireless nodes?
Free-space path loss increases by 6 dB when distance or frequency doubles, as defined by the Friis transmission equation.
6. What is the key benefit of using 802.11ax (Wi-Fi 6) APs in an outdoor high-density deployment such as a sports venue parking area?
OFDMA in Wi-Fi 6 subdivides channels into resource units, enabling parallel transmissions to multiple clients and improving dense-environment efficiency.
