Abstract
A system for wireless communication using ultrasonic signals that includes a transmission module, which receives input signals from a wireless device, modifies the received input signals in a manner that converts each received input signal into a corresponding ultrasonic signal and wirelessly transmits each said ultrasonic signal over an ultrasonic link, and a receiving module, which receives the transmitted ultrasonic signals, recovers the corresponding input signals therefrom and enables outputting each respective input signal through one or more output devices. Modification of the input signals may include compressing, encoding and modulating the input signals. The input signals may be voice audio signals for enabling to use the system for supporting phone calls by enabling ultrasonic communication between for instance, a wireless headset and a mobile phone. Transmission and receiving modules may be associated with a wireless headset and mobile phone for allowing ultrasonic and optionally RF communication therebetween.
