Match each wireless signal issue with its primary cause or physical manifestation.
- Signal AttenuationRF energy weakening as it passes through dense concrete walls, lowering the RSSI.
- Co-Channel InterferenceMultiple neighboring access points broadcasting on the same 2.4 GHz channel, causing contention.
- Multipath InterferenceRF signals bouncing off metal obstacles, causing delayed signal arrivals at the receiver.
- RefractionRF signals bending when passing through mediums of different densities, altering propagation direction.
Cevap
Signal Attenuation pairs with RF energy weakening through dense walls; Co-Channel Interference pairs with access points broadcasting on the same channel; Multipath Interference pairs with RF signals bouncing off metal obstacles; Refraction pairs with RF signals bending when passing through different mediums.
Each wireless propagation phenomenon is paired directly with its underlying physical behavior or cause: attenuation reduces signal strength over distance/materials; co-channel interference stems from frequency overlap; multipath occurs via signal reflection; refraction is signal deflection through differing media density.
