With respect to the dramatic increasing use of electronically communicators and wireless modems, concerns have been raised about the possible effects of emitted electromagnetic radiation on human brain. In this paper, the effects of high-frequency wireless modem waves on the brain signal are investigated. To this end, the Electroencephalograph (EEG) recording of 15 volunteers is examined in four different bands. The experiments are designed to cover in four steps. Average power statistical analysis in different frequency bands and magnitude-squared coherence function shows significant changes in some bands.
