Which frequency band provides the longest range but lowest throughput in typical WLAN deployments?
Answer: 2.4 GHz
The 2.4 GHz band propagates farther due to its lower frequency but offers lower throughput and more interference than 5 GHz.
What is the purpose of an active site survey compared to a passive one?
Answer: It transmits test traffic to measure throughput, latency, and packet loss
An active site survey transmits actual data packets to test real-world throughput, latency, and packet loss under load.
What is the significance of the Fresnel zone in wireless network planning?
Answer: It is the elliptical area around the line of sight that should be kept clear for optimal signal propagation
Obstructions within the Fresnel zone cause signal diffraction and attenuation, so keeping at least 60% clear is critical for optimal links.
When planning AP placement to achieve -67 dBm or better throughout an office, a specialist should consider which factor first?
Answer: Physical obstructions and building materials
Building materials like concrete, metal, and glass cause significant RF attenuation that directly affects coverage planning.
What is the typical channel width used for 802.11ac (Wi-Fi 5) deployments to maximize throughput?
Answer: 80 MHz
80 MHz channels are the standard for 802.11ac deployments, balancing high throughput with reasonable interference management.
Which site survey deliverable is most important for client approval and project documentation?
Answer: A formal report with floor plan AP placement, channel plan, and coverage heat maps
A formal report with AP placement diagrams, channel plans, and coverage heat maps serves as the official design record and client deliverable.
