Abstract: Technologies directed to a wireless device with a Radio Frequency (RF) Decibel-Scaled Wireless Interference Detector that provides accurate energy readings of a channel through decibel-scaled output voltage are described. One method of the wireless device includes receiving a first RF signal via an antenna and converting the first RF signal to a multiple samples using a sampling rate, each sample including a digital value of a decibel-scaled output voltage. The method converts each of the samples to an energy value using a voltage-to-energy lookup table and determines a congestion level of a channel using the energy values.
