What is the primary purpose of a pre-deployment site survey in a CWS context?
Answer: To determine AP placement and coverage requirements before installation
A pre-deployment site survey identifies coverage needs, obstructions, and optimal AP placement before any hardware is installed.
Which tool is most commonly used during a passive site survey?
Answer: A laptop with Wi-Fi adapter and site survey software
Passive surveys use a laptop with a Wi-Fi adapter and survey software to listen to existing RF signals without transmitting.
What does RSSI stand for in wireless site surveys?
Answer: Received Signal Strength Indicator
RSSI (Received Signal Strength Indicator) measures the power level of a received wireless signal, expressed in dBm.
What is the recommended minimum RSSI value (in dBm) for reliable VoIP over Wi-Fi?
Answer: -67 dBm
A minimum RSSI of -67 dBm is commonly recommended for VoIP applications to ensure low latency and packet loss.
During a site survey, a wireless specialist notices high co-channel interference on all 2.4 GHz channels. What is the best corrective action?
Answer: Migrate affected devices to the 5 GHz band
Migrating devices to the 5 GHz band reduces co-channel interference because 5 GHz has more non-overlapping channels.
What is a heat map in the context of a wireless site survey?
Answer: A visual representation of signal strength across a floor plan
A heat map overlays signal strength data onto a floor plan to visually show coverage areas and dead zones.
