Feature Descriptions........................................................................................................................ //
MU-MIMO
The AP supports MU-MIMO. MU-MIMO technology allows an AP to send data to multiple STAs at the same time (currently, most
802.11n/11ac Wave 1 APs can only send data to one STA simultaneously). The technology marks the start of the 802.11ac Wave 2 era.

GE access
The APs support the 80-MHz bandwidth mode. Frequency bandwidth increase brings extended channels and more sub-carriers for data
transmission, and a 2.16-fold rate increase. Support for High Quadrature Amplitude Modulation (HQAM) at 256-QAM increases the 5 GHz
radio rate to 867 Mbit/s and the AP rate to 1.267 Gbit/s.
Cloud-based management
Huawei Cloud Managed Network (CMN) Solution consists of the cloud management platform and a full range of cloud managed network
devices. The cloud management platform provides various functions including management of APs, tenants, applications, and licenses,
network planning and optimization, device monitoring, network service configuration, and value-added services.
High Density Boost technology
Huawei uses the following technologies to address challenges in high-density scenarios, including access problems, data congestion, and
poor roaming experience:
•
Interference suppression
ˉ In high-density scenarios, APs are usually densely placed. Huawei uses small-angle antennas that are purpose-built for highdensity scenarios to mitigate interference. These antennas have good radiation angle control and can regulate AP coverage radius
to within the appropriate range. Additionally, Huawei's Clear Channel Assessment (CCA) optimization technology reduces the
possibility of air interface resources shared by multiple devices, allows higher user access, and improves the throughput.
•
Air interface performance optimization
ˉ In high-density scenarios where many users access the network, increased number of low-rate STAs consumes more resources on
the air interface reduces the AP capacity, and lowers user experience. Therefore, Huawei APs will check the signal strength of STAs
during access and rejects access from weak-signal STAs. At the same time, the APs monitor the rate of online STAs in real time and
forcibly disconnect low-rate STAs so that the STAs can reassociate with APs that have stronger signals. The terminal access control
technology can increase air interface use efficiency and allow access from more users.
•
5G-prior access (Band steering)
ˉ The APs support both 2.4G and 5G frequency bands. The 5G-prior access function enables an AP to steer STAs to the 5 GHz
frequency band first, which reduces load and interference on the 2.4 GHz frequency band, improving the user experience.
•
Load balancing between APs
ˉ After the load balancing function is enabled, the AC distributes users evenly to APs based on user quantity and traffic volume.
Traffic load is therefore balanced among APs to ensure stable AP performance.
•
Smart roaming
ˉ Smart roaming technology is based on the 802.11k , 802.11v and 802.11r technologies and allows STAs to connect to APs with
stronger signals, improving user experience and the overall performance of the wireless network.
•
Agile Beam
ˉ Agile antenna polarization beam automatic adaption.

Wired and wireless dual security guarantee
To ensure data security, Huawei APs integrate wired and wireless security measures and provide comprehensive security protection.
•
Authentication and encryption for wireless access
ˉ The APs support WEP, WPA/WPA2–PSK, WPA/WPA2–802.1x, and WAPI authentication/encryption modes to ensure security of the
wireless network. The authentication mechanism is used to authenticate user identities so that only authorized users can access
network resources. The encryption mechanism is used to encrypt data transmitted over wireless links to ensure that the data can
only be received and parsed by expected users.
•
Analysis on non-Wi-Fi interference sources
ˉ Huawei APs can analyze the spectrum of non-Wi-Fi interference sources and identify them, including baby monitors, Bluetooth
devices, digital cordless phones (at 2.4 GHz frequency band only), wireless audio transmitters (at both the 2.4 GHz and 5 GHz
frequency bands), wireless game controllers, and microwave ovens. Coupled with Huawei eSight, the precise locations of the
interference sources can be detected, and the spectrum of them displayed, enabling the administrator to remove the interference
in a timely manner.
•
Rogue device monitoring
ˉ Huawei APs support WIDS/WIPS, and can monitor, identify, defend, counter, and perform refined management on the rogue
devices, to provide security guarantees for air interface environment and wireless data transmission.
•
AP access authentication and encryption
ˉ The AP access control ensures validity of APs. The CAPWAP link protection and DTLS encryption provide security assurance,
improving data transmission security between the AP and the AC.
Automatic radio calibration
Automatic radio calibration allows an AP to collect signal strength and channel parameters of surrounding APs and generate AP topology
according to the collected data. Based on interference from authorized APs, rogue APs, and non-Wi-Fi interference sources, each AP
automatically adjusts its transmit power and working channel to make the network operate at the optimal performance. In this way,
network reliability and user experience are improved.
Automatic application identification
Huawei APs support smart application control technology and can implement visualized control on Layer 4 to Layer 7 applications.
•
Traffic identification
ˉ Coupled with Huawei ACs, the APs can identify over 1600 common applications in various office scenarios. Based on the
identification results, policy control can be implemented on user services, including priority adjustment, scheduling, blocking, and
rate limiting to ensure efficient bandwidth resource use and improve quality of key services.
•
Traffic statistics collection
ˉ Traffic statistics of each application can be collected globally, by SSID, or by user, enabling the network administrator to know
application use status on the network. The network administrator or operator can implement visualized control on service
applications on smart terminals to enhance security and ensure effective bandwidth control.
