Abstract

Near Field Communication (NFC) is a technology for wireless short-range communication. The main attribute of NFC is proximity and that data transmission will take place only within a very small area. However, NFC-based applications are still not prevalent due to slow progress of NFC hardware penetration. In this paper, we present A-NFC, an NFC-like communication system, which operates on existing mobile phones. It is an inaudible acoustics-based system utilizing the microphones and speakers on mobile phones. In addition, A-NFC is purely software based and can run on different operating systems. A-NFC implements full-duplex two-way communication by designing two independent channels in the inaudible frequency band. To the best of our knowledge, A-NFC is the first acoustics communication system capable of inaudible and two-way communications on various popular platforms (Android and iOS included). Extensive experiments demonstrate that A-NFC can reliably provide NFC capability with a data rate up to 2.2 Kbps on various devices.

A-NFC:通过听不见的声学进行双向近场通信(NFC)

近场通信(NFC)是一种无线近距离通信技术。NFC的主要特性是接近性，数据传输只会在很小的区域内进行。然而，由于NFC硬件渗透的进展缓慢，基于NFC的应用仍然不普遍。在本文中，我们提出了A-NFC，一种类似nfc的通信系统，它可以在现有的移动电话上运行。这是一种利用移动电话上的麦克风和扬声器的不可听声学系统。此外，A-NFC完全基于软件，可以在不同的操作系统上运行。A-NFC通过在不可听频段内设计两个独立的信道来实现全双工双向通信。据我们所知，A-NFC是第一个能够在各种流行平台(包括Android和iOS)上进行听不见和双向通信的声学通信系统。大量的实验表明，a -NFC可以在各种设备上可靠地提供高达2.2 Kbps的数据速率的NFC功能。
