CloudEngine S12700E does not support PoE. PoE is a technology that allows network devices to receive power from data cables instead of power cables. PoE is usually used for access switches that connect to devices such as IP phones and wireless APs, but not for core switches such as CloudEngine S12700E. A single CloudEngine S12700E can manage up to 10K APs by integrating native WLAN AC capabilities4. A single CloudEngine S12700E can manage up to 50K terminals by using free mobility feature that ensuresconsistent user experience across wired and wireless networks4. CloudEngine S12700E integrates hardware-based OAM/BFD to provide fast fault detection and location for various services such as Ethernet, IP, MPLS, and VxLAN

AirEngine is Huawei’s newest brand name of Wi-Fi products. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei launched its new brand name AirEngine for its Wi-Fi products in April 2019, aiming to provide ubiquitous connectivity, mobility, and intelligence for enterprises.

The model that is not included in the CloudEngine S7700 family is S7709. The CloudEngine S7700 family consists of three models: S7703, S7706, and S7712. These are smart routing switches designed for next-generation enterprise networks, with features such as wired and wireless convergence, unified user management, quality awareness, and SVF 2.04

CE6820 does not support 100GE uplink ports. According to the CloudEngine S6800 Series Switches Datasheet, CE6820 supports 48 x 10GE ports and 4 x 40GE ports, but not 100GE ports.

WPA3 is a new security protocol for wireless networks that provides enhanced security and privacy features compared to WPA2 . One of the advantages of WPA3 is that it eliminates the potential for dictionary attacks, which are a type of brute-force attack that tries to guess passwords by using a list of common words or phrases . WPA3 uses a more robust authentication mechanism called Simultaneous Authentication of Equals (SAE), which prevents offline password cracking attempts . The other statements are correct advantages of WPA3. WPA3 can encrypt data on open SSIDs using Opportunistic Wireless Encryption (OWE), which creates a unique encryption key for each user without requiring any credentials . WPA3 also meets the NSA/SuiteB security requirements of governments and banks, which specify the use of strong encryption algorithms such as AES-256 and Elliptic Curve Cryptography (ECC) . WPA3 also ensures that even if an attacker obtains the intermediate key during the handshake process, they cannot decrypt the data or derive the session key, thanks to a feature called forward secrecy .

Each AP does not need to be designed to cover as large an area as possible in order to provide better coverage in a high-density scenario. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, in a high-density scenario, each AP should be designed to cover a small area with high signal strength and low interference, which can improve user experience and network capacity.

The iMaster NCE-Fabric cannot be deployed in a single-node system. According to the iMaster NCE-Fabric Product Overview, iMaster NCE-Fabric is a distributed system that consists of three nodes: the management node, the control node, and the analysis node. The management node provides basic management functions, such as configuration, monitoring, and alarm management. The control node provides control functions, such as VXLAN tunnel establishment and policy association. The analysis node provides analysis functions, such as network health analysis, fault diagnosis, and performance optimization.

Dielectric constant does not affect radio throughput. According to Shannon’s theorem4, radio throughput is determined by the bandwidth and the signal-to-noise ratio of the channel. Dielectric constant is aproperty of the medium that affects the propagation speed and wavelength of electromagnetic waves, but not the information-carrying capacity.

The NE8000M1C supports dual AC/DC power modules. According to the NetEngine 8000 M1C Service Router Datasheet, NE8000M1C supports two power modules that can work in 1+1 redundancy mode. The power modules can be AC or DC power modules.

NetEngineAR611W is a desktop router that is designed for small enterprises and SOHO enterprises. It integrates security and Wi-Fi functions, and its design is risk-free. NetEngineAR611W supports multiple WAN interfaces, such as ADSL2+, VDSL2, GE, and LTE. It also supports firewall, VPN, IPSec, NAT, and other security features. NetEngineAR611W can provide Wi-Fi coverage for up to 32 users.

CloudEngine S5732-H series multi-GE switches do not deliver a switching performance of 1760 Gbit/s. According to the CloudEngine S5732-H Series Multi-GE Switches Datasheet, CloudEngine S5732-H series multi-GE switches deliver a switching performance of up to 336 Gbit/s.

SDR (Software Defined Radio) is a technology that can be used to switch the number of RFs (Radio Frequencies) dynamically. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, SDR enables an AP to dynamically switch between 2.4 GHz and 5 GHz bands based on the number of users and service requirements, improving spectrum utilization and user experience.

M-LAG (Multi-Chassis Link Aggregation Group) is the recommended networking mode for leaf switches. According to the Huawei CloudFabric Data Center Network Solution White Paper, M-LAG enables multiple leaf switches to form a logical device that provides high availability, load balancing, and simplified management.
