NFMI能够让电子设备之间进行非接触式点对点数据传输，从免接触式射频识别（RFID）演变而来的，由恩智浦半导体、诺基亚和索尼共同研制开发。 NFMI属于短距高频的无线电技术，通过磁场感应方式实现无线通信，工作在10MHz到14 MHz的载波频率范围内，运行有效距离很短，只有20cm。 无线发射功率只有1.62mW（工作电压1.2V，工作电流1.35mA），对人体的辐射伤害很小，可用于助听器等双耳互传通信领域。 它的传输速度有三种，分别是106 Kbit/s、212 Kbit/s或 …

与使用 2.4ghz 的蓝牙通信相比，近场磁感应 (nfmi) 技术可在邻近人体的区域提供更可靠、更安全、更低功耗的无线电链路。 本文首先将概述 nfmi 技术，并将它与 nfc 和蓝牙进行比较。其次介绍 nxp 的 nfmi 产品，它们是无线人体区域网络 (wban) 通信的解决方案。

SD10，1T版，标称 读5000MB/s 写3900MB/s。 使用 群联5021E主控，铠侠原厂 3D TLC颗粒。 这是无缓盘，经典的三段式写入，初始速度2.5G/s，降低到600MB/s左右，再到300MB/s左右。 1T版实际容量950G左右。 入门级原厂PCIe4.0，个人认为，不算差。 现在固态硬盘涨价，PCIe3.0的RC20，也要399，相对来说，这个会更好一些。 说个冷知识：西数和铠侠合作建厂，西数、海力士等企业，都有铠侠股份。

Abstract: Magnetic-induction-based nearfield communication is an emerging technology that is used for short-range, Internet-of-Things applications requiring high security, human safety, and low power; it operates in harsh environments, withstanding the presence of …

A near-field magnetic induction (NFMI) communication system is a short range wireless physical layer that communicates by coupling a tight, low-power, non-propagating magnetic field between devices. The concept is for a transmitter coil in one device to modulate a magnetic field which is measured by means of a receiver coil in another device.
