Alarm An Alarm is triggered by any event with severity Error or higher (see

Section 8.2, “Events”).

Adaptive mode of receiver opera-

tion

Cognitive function of receiving mode selection is implemented in

RipEX2. When exposed in a radio environment where strong inter-

fering signals (stronger than -45 dBm) are present, RipEX2 senses

them and adaptively increases its resistance to interference (and

lowers its sensitivity by 3 dB). When interference holds, RipEX2

stays in high resistance mode of receiver operation and signals this

state by turning the yellow RX LED on. Once the interfering signals

fade away, RipEX2 automatically returns to its high sensitivity mode

of receiver operation.
