Most of the time, they waste a significant amount of energy when operated under favourable channel conditions. Energy efficient and accurate channel state classification is imperative for selecting the optimum trade-off between transceiver performance and amount of saved energy, without impacting transmission quality. This work presents a novel, low complexity channel state indicator and a simple mono-feature classifier for channel state recognition. The classifier is trained using a set of experimental data acquisitions and has a 96% accuracy when tested with a new collected data set. Specially designed for LPWA applications, the classifier is capable of distinguishing undisturbed channels from those suffering from both mobility-induced fading and interference, while operating at low to medium SNR. %G English %2 https://cea.hal.science/cea-01972976/document %2 https://cea.hal.science/cea-01972976/file/COMSNETS.pdf %L cea-01972976 %U https://cea.hal.science/cea-01972976 %~ CEA %~ UGA %~ CNRS %~ INPG %~ GIPSA %~ GIPSA-DIS %~ GIPSA-DA %~ GIPSA-SAIGA %~ PERSYVAL-LAB %~ DSV %~ DRT %~ CEA-DRF %~ LETI %~ CEA-GRE %~ POLYTECH-GRENOBLE %~ UGA-COMUE %~ ANR
