With all the technology available in the form of electronics, mechanics, and software, if it were possible to efficiently and effectively implement systems of ultrasonic communications, such devices would be as common as the current plethora of wireless systems. Some early research efforts at ultrasonic communications were published in a 1945 edition of Radio News. Regardless of the era, the electromagnetic frequency bands are always deemed to be too crowded so researchers … http://www.rfcafe.com/references/radio-news/ultrasonic-communications-october-1945-radio-news.htm
