These units provide low-level management service interfaces through which low-level management functions can be invoked.
为了提供正确的MAC操作，每个STA(包括Non-AP STA和AP STA)中都有一个高层管理单元，如SME(station management entity，设备管理单元)，SME表示在MAC层之上的高层管理单元，是一个独立于层的单元，它位于单独的管理平面中。In order to provide correct MAC operation, each STA (including Non-AP STA and AP STA) has a high-level management unit, such as SME (station management entity, equipment management unit), SME means high-level management above the MAC layer A unit, which is a layer-independent unit, resides in a separate management plane.
SME的作用：通常，该单元负责诸如从各种层管理单元(MLME和PLME)收集与层相关的状态之类的功能，类似地，其还会设置特定于层的参数值。SME通常代表一般的系统管理实体执行此类功能。图1描述了管理单元之间的关系。Role of the SME: Typically, this unit is responsible for functions such as collecting layer-related status from the various layer management units (MLME and PLME), and similarly setting layer-specific parameter values.

As the use of wireless local area networks (WLANs) continues to grow, it is increasingly important to provide wireless data services in many environments such as homes, businesses and hotspots. In particular, video traffic will continue to be the dominant traffic type in many WLAN deployments. Throughput requirements for these applications are evolving due to the advent of 4k and 8k video (20Gbps uncompressed). New high-throughput, low-latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., real-time gaming with sub-5ms latency).
鉴于这些应用程序的高吞吐量和严格的实时延迟要求，用户期望通过WLAN支持其应用程序时，吞吐量更高，可靠性更高，延迟和抖动更少，电源效率更高。用户期望改进与时敏网络(TSN)的集成，以支持异构以太网和无线LAN上的应用程序。802.11be网络旨在通过进一步提高总吞吐量和降低延迟来确保WLAN的竞争力，同时确保与旧版技术标准向后兼容和共存。在2.4GHz，5GHz和6GHz频段运行的802.11兼容设备。Given the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency and jitter, and better power efficiency when supporting their applications over WLAN. Users expect improved integration with time-sensitive networking (TSN) to support applications over heterogeneous Ethernet and wireless LANs. 802.11be networks are designed to ensure WLAN competitiveness by further increasing overall throughput and reducing latency, while ensuring backward compatibility and coexistence with older technology standards. 802.11 compliant devices operating on the 2.4GHz, 5GHz and 6GHz bands.
