摘要：Short range wireless communications have been used more and more frequently in our life. But theelectromagnetic fields waves also have some disadvantages. One of these disadvantages is health problems.Many studies shows the electromagnetic field waves using for communication may damage our health. Andin most hospitals, they also have bans on the use of mobile phones and wide area networks because ofElectromagnetic Interference. So this paper studied the use of ultrasound for wireless communication inair, instead of using electromagnetic field wave. In order to find an advisable modulation method forultrasound wireless communication, Amplitude modulation method and Phased modulation method hasbeen test
