论文摘要
在本文中，我们提出了BATNET，这是一种使用超声信号的数据传输机制，对智能手机的内置扬声器和麦克风。使用8点星座和20-24kHz之间的频率使用相移键，它可以以超过600位/s的速度传输数据，最高为6m。目标应用程序是耐心的网络网络。我们还对此进行了评估，以进行共同接触跟踪，但得出的结论是，在此应用程序中，超声波通信似乎没有比蓝牙低能提供足够的优势，值得进一步发展。
In this paper, we present BatNet, a data transmission mechanism using ultrasound signals over the built-in speakers and microphones of smartphones. Using phase shift keying with an 8-point constellation and frequencies between 20--24kHz, it can transmit data at over 600bit/s up to 6m. The target application is a censorship-resistant mesh network. We also evaluated it for Covid contact tracing but concluded that in this application ultrasonic communications do not appear to offer enough advantage over Bluetooth Low Energy to be worth further development.
