CWS Site Survey & Network Planning Flashcards

What does a cell overlap of approximately 15–20% between adjacent APs achieve in a WLAN design?

Answer: Ensures seamless roaming with consistent coverage

A 15–20% cell overlap ensures clients can roam between APs without dropping the connection or experiencing coverage gaps.

When conducting an outdoor wireless site survey, which environmental factor is most likely to cause signal multipath?

Answer: Reflections off buildings, vehicles, and the ground

Reflections from hard surfaces cause multipath propagation, where multiple signal copies arrive at the receiver at slightly different times.

What is the purpose of defining a Minimum Viable Signal (MVS) threshold during network planning?

Answer: To establish the lowest acceptable signal level at which devices should operate

The MVS threshold sets the baseline signal level below which device performance is unacceptable, guiding AP placement decisions.

What is the advantage of conducting a predictive site survey using software tools before a physical survey?

Answer: It provides an estimated RF model to guide AP placement, saving time and cost

Predictive surveys use RF modeling software to simulate coverage, helping planners identify AP counts and positions before on-site work.

A specialist is planning a high-density wireless deployment for a stadium. Which design approach is most appropriate?

Answer: Use low-power, directional APs deployed in an under-seat or overhead pattern to reduce cell size

High-density deployments require small cells with low transmit power and directional antennas to serve many clients per unit area.

Which document type created during site survey planning defines the maximum number of clients per AP?

Answer: Capacity planning worksheet

A capacity planning worksheet calculates client density, application requirements, and expected throughput to determine AP count and placement.
