MIMO (Multiple-Input Multiple-Output) is a core pillar of modern WLAN planning. It utilizes two main techniques:

Spatial Multiplexing (SM): Increases system capacity by transmitting different data streams over different antennas simultaneously.

Spatial Diversity (SD): Improves coverage scope and SNR (Signal-to-Noise Ratio) by transmitting the same data stream over multiple paths to ensure reliability through redundancy (e.g., using MRC or STBC).

The statement is True because these benefits are achieved using the same frequency channel (no extra bandwidth) by exploiting the spatial dimension of the radio environment.

A functional Huawei SD-WAN network requires three fundamental pillars:

CPE (A): The physical or virtual edge device at the branch/HQ.

RR (B): The control plane component that reflects routes between CPEs.

Controller (C): The management plane (iMaster NCE-Campus) for orchestration and policy deployment.

The Analyzer (D) (CampusInsight) is an optional component used for advanced AI-driven O&M and troubleshooting, but it is not strictly required to establish the SD-WAN network itself.

In a modern campus network, unified identity management is critical. iMaster NCE-Campus acts as a RADIUS and Portal server that integrates with existing enterprise directories. It supports synchronization and authentication against Microsoft Active Directory (AD), LDAP, and third-party databases via standard protocols. This enables features like SSO (Single Sign-On) and ensures that user permissions are consistent with their existing corporate credentials.

Effective VLAN planning is a cornerstone of campus design. Huawei supports all four methods:

Service Type (B): Segregating Voice, Data, and Management traffic.

Geographic Area (C): Assigning VLANs per floor or building.

Logical Area (A): Grouping by functional zones (e.g., Server zone, DMZ).

Workforce Structure (D): Mapping VLANs to departments (e.g., HR, R&D, Finance).

Modern designs often use a combination, which can be further simplified using Free Mobility (Security Groups).

Huawei's wireless health model in CampusInsight is specifically 'Experience-Centric.' It evaluates the network based on five dimensions of user experience: Access (A), Throughput (C), Roaming (D), Capacity, and Interference. While the physical status of a device (on/off) is monitored, 'Network Status' is not one of the metrics used to calculate the specific Experience Health Score in this evaluation model.
