Match each wireless network symptom described on the left with its primary physical or radio frequency (RF) root cause on the right.
- High frame retransmission rates and latency near metal warehouse racks despite strong RSSI measurements.RF reflection leading to multipath signal distortion and delay spread.
- Intermittent 2.4 GHz Wi-Fi connection drops in an office area adjacent to a breakroom during lunch hours.Non-802.11 electromagnetic interference within the 2.4 GHz ISM frequency band.
- A sudden, drastic drop in signal strength (dBm) immediately after entering a room surrounded by reinforced concrete.High RF attenuation caused by dense building materials absorbing the signal.
- Severe throughput degradation on two nearby access points assigned to 2.4 GHz channels 2 and 3.Adjacent-channel interference caused by non-overlapping channel misconfiguration.
Cevap
High frame retransmissions near metal racks match RF reflection and multipath distortion. Intermittent drops near breakrooms match non-802.11 2.4 GHz interference. Signal drops behind reinforced concrete match RF attenuation. Performance drops on channels 2 and 3 match adjacent-channel interference.
Each symptom directly corresponds to a fundamental RF behavior: metal causes reflection and multipath delay spread; active microwave ovens create non-802.11 2.4 GHz interference; reinforced concrete causes high RF attenuation; and selecting channels 2 and 3 violates non-overlapping 2.4 GHz channel design (1, 6, 11), producing adjacent-channel interference.
