Compared to the 4G network, 5G features enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), and massive machine-type communications (mMTC). These three attributes define what 5G is, and imply the basic requirements for storage devices running on a 5G network. Due to the fact that higher frequency signals are easily blocked by obstacles, microinfrastructure plays a critical role in expanding network coverage, guaranteeing high-speed performance, and ensuring high reliability. Therefore, reliable storage devices are fundamental for efficient operations.
