Near Field Magnetic Induction (NFMI) based communication is an emerging technology that promises several advantages over the traditional radio frequency (RF) communication including low energy use, ability to work reliably in a variety of difficult propagation media (e.g., water, non-ferromagnetic metals, underground, tissue media of fresh produce & meats, etc.), and low leakage possibility because of fast decay. Furthermore, since the MI technology is useful for efficient power transfer as well, it provides the possibility of passive tagging as well. In this paper, we provide a technical overview of NFMI technology and its potential for several applications in RF challenged environments. We also lay out a number of challenges with NFMI technology and its use in various applications.

基于近场磁感应（NFMI）的通信是一项新兴技术，与传统的射频（RF）通信相比，具有许多优势，包括低能耗，在各种困难的传播介质（例如水，非铁磁）中可靠工作的能力金属，地下，新鲜农产品和肉类的组织介质等），并且由于快速腐烂而泄漏的可能性很小。此外，由于MI技术也可用于有效的功率传输，因此它也提供了无源标记的可能性。在本文中，我们对NFMI技术及其在RF挑战环境中的多种应用的潜力进行了技术概述。我们还对NFMI技术及其在各种应用中的使用提出了许多挑战。
