射频（RF）通信虽然最流行，但不适合于涉及水性和动物/植物组织介质的环境、密集环境（例如，具有许多无线电的小区域）、需要极低功耗的应用等。对于这样的环境，磁感应（MI）通信是一种看起来非常有吸引力的新兴技术。虽然MI通信已经研究了一些RF挑战的环境，如水下，地下和体域网，到目前为止，大多数的研究是基于最少的实验仿真。在本文中，我们提出的MI通信的可行性，通过开发一个小型的测试平台，使用Freelinc板。我们还比较和对比现有的理论主张MI通信与一些详细的实验结果，并显示它们有多大的不同。
Radio frequency (RF) communications, although most popular, are unsuitable for environments involving aqueous and animal/plant tissue media, dense environments (e.g., small regions with many radios), applications requiring extremely low power consumption, etc. For such environments, magnetic induction (MI) communications are an emerging technology that appears to be very attractive. Although MI communication has been studied for some RF-challenged environments such as underwater, underground and body area networks, most of the studies so far are simulation based with minimal experimentation. In this paper, we show the feasibility of the proposed MI communications, by developing a small testbed using Freelinc boards. We also compare and contrast the existing theoretical claims regarding MI communications with some detailed experimental outcomes, and show how much they differ.
