Which one of the following options would you consider a well-designed WLAN infrastructure when measuring RSSI, Noise Floor, and SNR in a required area?
RSSI (Received Signal Strength Indicator):Higher RSSI indicates stronger signal reception.
Noise Floor:Lower noise floor improves clarity of communication.
SNR (Signal-to-Noise Ratio):A high SNR is required for good throughput and reliability.
A well-designed WLAN will have:
High RSSI (strong signal)
Low Noise Floor (less interference)
High SNR (clear distinction between signal and noise)
From CWDP-305:
“A strong, clean signal (high RSSI, low noise) results in higher SNR, which directly correlates with better performance and fewer retransmissions.”
