This chapter developed a machine learning approach for indoor environment classification based on real-time measurements of the RF signal. Several machine learning classification methods were contemplated, including DTs, SVM, and k-NN, using different RF features. Results obtained show that a machine learning approach using k-NN method, utilizing CTF and FCF, outperforms the other methods in identifying the type of the indoor environment with a classification accuracy of 99.3%. The predication time was obtained to be less than 10 u,s, which verifies that the embraced algorithm is successful for real-time deployment scenarios. The results of this chapter facilitate an efficient deployment of IoT applications in dynamic channels
