The magnetoquasistatic (MQS) field coupling theory is presented for long ranges between a transmitting device located outdoor to a receiving device located indoor. The theory is validated based on measurements in a large indoor house environment ($>$8000 ft$^2$) with the transmitting device located far outside the house ($>$11 m from outer wall). We discuss the system and demonstrate position sensing for a compact mobile MQS receiver device in the house.

长距离穿墙磁准静态耦合及其在室内位置传感中的应用

针对位于室外的发射设备和位于室内的接收设备之间的长距离，提出了准磁 (MQS) 场耦合理论。该理论基于在大型室内房屋环境中的测量得到验证（$>$8000 英尺$^2$) 发射设备位于房子外面很远的地方 ($>$距外墙 11 m）。我们讨论了该系统并演示了房屋中紧凑型移动 MQS 接收器设备的位置感测。
