Read the first 6 CWDP Antenna Design and Placement flashcards as text

  1. Which antenna type radiates energy equally in all horizontal directions, making it ideal for open-office deployments?

    Answer: Omnidirectional

    Omnidirectional antennas radiate in a 360-degree horizontal pattern, providing even coverage in open areas.

  2. What does 'antenna gain' measure in the context of WLAN design?

    Answer: Concentration of radiated energy in a specific direction

    Antenna gain measures how much energy is focused in a particular direction compared to a reference antenna.

  3. A CWDP designer needs to cover a long narrow hallway. Which antenna type is most appropriate?

    Answer: Yagi directional

    A Yagi antenna's narrow, high-gain beam pattern is well-suited for long, narrow spaces like hallways.

  4. What is the primary effect of antenna downtilt in a multi-floor building deployment?

    Answer: Reduces co-channel interference on adjacent floors

    Downtilting an antenna directs the main lobe toward the intended coverage area, limiting signal bleed to other floors.

  5. Which polarization mismatch scenario results in the greatest signal loss?

    Answer: One vertical and one horizontal polarization

    A 90-degree polarization mismatch between transmitter and receiver can cause up to 20 dB of signal loss.

  6. What does EIRP stand for and what does it represent in WLAN design?

    Answer: Effective Isotropic Radiated Power — total power radiated by the antenna system

    EIRP is the effective isotropic radiated power, combining transmit power and antenna gain minus cable losses.
