Resumo


Current consumer devices, such as TVs, smartphones, smartwatches,etc., often come with built-in support for radio-frequency (RF) wireless communication. This support requires RF hardware and de-ends on technologies such as Bluetooth, IEEE 802 WiFi, or 4Gmobile networks. There are situations, however, where the RF data network is not available, or where it is more advantageous to use some other form of wireless communication. One alternative communication through inaudible sound. The same consumer devices that come with RF support usually come equipped with speakers and microphones which enables them to produce and detect inaudible sound. By inaudible sound, we mean sound waves in frequencies that cannot be heard by humans—usually those above 19–22 kHz. Many works in the literature that show that communication through inaudible sound is feasible on consumer-grade PCs, laptops, and smartphones. Here we are mainly concerned with the applicability of this technique to enable inaudible sound applications in the Ginga-NCL engines. This way, we propose a new type of media object called SigGen.
