Refer to the exhibit. An engineer is troubleshooting non-802 11 interference and observes this output. Which type of interference signatures can the engineer identify?

Microwave ovens typically exhibit a very broad, often periodic, burst of energy across a significant portion of the 2.4 GHz spectrum.

DECT (Digital Enhanced Cordless Telecommunications) phones operate in the 1.9 GHz frequency band, and their pulsed, wideband emissions can cause significant interference to 2.4 GHz Wi-Fi networks. Spectrum analysis tools often show specific, recurring patterns that are easily identifiable as DECT phone activity, distinct from other interference sources.

Bluetooth devices use frequency hopping spread spectrum and usually appear as rapid, narrow-band bursts that quickly change frequencies.

Jammers produce a sustained, high-power noise floor across a wide frequency range, effectively blocking all communications within that spectrum.
