Certain patents detail specialized equipment designed to operate at ultra-low frequencies (1-2 Hz and higher) or ultra-high frequencies (such as 1000 Hz and higher), with wireless towers being particularly suitable for the latter.
It is important to recognize that these documents are patents, not necessarily validated technologies. Nevertheless, some of these initiatives have been fully realized, and their titles openly reflect the ultimate aim of these research efforts—the subtle impact on human consciousness and subconsciousness.
