A spectrum waterfall at a municipal warehouse shows narrow frequency-hopping bursts marching across 2.4 GHz. How should the expert classify that signature relative to Wi-Fi?
Select an answer to reveal the explanation.
Short Explanation
Those skinny hops skipping across the band look like a flea circus, not a Wi-Fi billboard parked on one channel. Hopping cordless/FHSS/IoT energy isn't OFDM Wi-Fi. Don't call every 2.4 GHz blip a beacon or an OFDMA trigger.
Full Explanation
Frequency-hopping spread spectrum and similar hoppers produce narrow bursts that change frequency over time on a waterfall, unlike stationary wide OFDM Wi-Fi channel occupations. Classifying the signature correctly guides remediation toward the non-Wi-Fi source rather than BSS channel retuning alone. OFDMA trigger frames are Wi-Fi MAC/PHY exchanges, not narrowband hop sweeps across the ISM band.
