A network technician is performing RF site troubleshooting in a manufacturing facility to resolve persistent wireless connectivity issues. Match each observed wireless symptom or environmental phenomenon on the left with its correct physical root cause or signal behavior on the right.
- Multipath distortion causing high frame retransmissionsRadio waves bounce off metal walls and machinery, reaching the receiver out of phase at slightly different times.
- RF attenuation causing rapid reduction in RSSIDense building materials such as concrete and masonry absorb radio energy as signals travel through obstacles.
- Non-802.11 ambient interference causing localized signal degradationUnshielded industrial microwave equipment emits uncoordinated RF energy across the 2.4 GHz frequency spectrum.
- Antenna polarization mismatch causing severe signal lossTransmitting and receiving antennas are aligned at orthogonal physical orientations, such as vertical to horizontal.
Answer
Multipath distortion matches signal reflection out of phase off metal surfaces; RF attenuation matches absorption by dense building materials; Non-802.11 interference matches RF noise from unshielded industrial microwave equipment; Antenna polarization mismatch matches orthogonal spatial antenna orientations.
Each wireless troubleshooting phenomenon is accurately matched to its underlying RF physical characteristic: reflection out of phase causes multipath, physical absorption by building materials causes attenuation, non-Wi-Fi electromagnetic emitters cause non-802.11 interference, and mismatched spatial alignment of antennas causes polarization loss.
